I've yet to find anything else that only takes 10 to 20 minutes a day that has a higher ROI. The amount of "compounding interest" it gives over time is incredible.
Learning to write good cards is skill that takes time and practice. The article from Andy Matuschak [0] is a great guide to learn how to write good cards.
He also emphasizes the importance of interleaving, which involves mixing up different types of problems or questions to enhance retention and facilitate transfer of knowledge. Additionally, he suggests that prompts should be personalized and contextualized to increase engagement and motivation.

Although already a power Emacs user, it was a significant step up when I started memorizing keystone for various modes via spaced repetition.
Can you imagine that there have been points in your job that would have gone smoother if you'd known more?
Understanding is efficiently arranging and coordinating those nodes in an efficient path for most situations
Wisdom is knowing in which contexts to actually apply that path of nodes
Tacit knowledge is similar to wisdom just it generally lacks memorisation
There's not a perfect mapping in English between Memorisation, Understanding and Wisdom and their most pragmatic corresponding analogues in nature, but I have found this distinction between terms useful in the whole memorisation v understanding debate
Adding nodes to your existing network of knowledge is learning facts. Memorization is making the nodes persistent. Both are important, but they're not equivalent. You need to do both.
You can learn without memorization (you can learn a lot and forget everything you've learned by the next day). You can memorize without learning the subject matter (for example, you can memorize a counting song in Mandarin Chinese without knowing that what you've memorized are numbers).
Flashcards can be used for learning, but they are optimized for memorization. We shouldn't expect them to be the best tool for learning, because that's not what they're designed for. One might get better results learning from another resource, and then using flashcards to memorize the concepts they've learned.
Learning facts, understanding how they correlate and memorizing both the facts and the correlations are all different steps. Memorization is useful and necessary, but it's not equivalent to learning and to understanding. Each step helps with the other steps. They can happen at the same time, but not necessarily.
In fact, I would argue that most of the forms of knowledge that are truly valuable are exactly the kinds that aren't amenable to memorization. Think about any skill that's in high demand and takes decades to master. You're not going to get there by studying Anki cards.
On the other hand, what a professional mathematician does is create new tools for proving theorems. This can't be memorized because, by definition, the knowledge didn't exist. It's true that they draw on previous experience having solved similar problems. But it's not clear to me that this knowledge is most efficiently gotten by drilling the same problems over and over.
I think this idea of using Anki for learning everything is misguided because it attempts to reduce complex topics and pragmatic know-how to a set of trivia questions. An example from the article: the author wanted to understand the AlphaGo paper, and some example flashcards were "who plays first in Go" and "where did AlphaGo get its training data". They probably could have acquired a much deeper understanding by playing a few games of Go and implementing a reinforcement learning algorithm for tic-tac-toe. Incidentally, that also sounds a lot more fun and motivating to me than studying flashcards.
You might if you were an editor. I guess your job probably doesn't have much to do with that so you see it as pointless but there is a different sphere of knowledge where having various things committed to memory would save you time. For instance, if we're interested in learning a new programming language, I guess most of us can understand a sentence like "a string is an immutable sequence of characters," quickly read it, and move on. If you weren't familiar with the concepts in that sentence you'd burn a lot more time before making heads or tails of it.
Can we? In the context of learning a new unfamiliar programming language… is it saying there is a string type or is it telling you that there isn’t a string type but only a sequence of characters? Like APL a string is an array of characters not its own type but in C# [string] is a thing and if you iterate it you get [char] type. In Prolog a string is traditionally a linked list of ASCII code numbers, there isn’t a string type or a char type … but there is still a string to chars conversion function. So is the sentence telling you that there is a char type? In Python a string is iterable but you get strings of length one for the characters rather than chars. But wait what about Unicode and surrogate pairs and glyphs, where does “sequence of characters” fit on those things in this language?
What does ‘sequence’ mean in this unfamiliar language - is it saying strings are an array or a list, or that sequence is a trait or behaviour which generalises over many types? What is immutable specifically, sequences or strings or characters or all data? What are the consequences of that? In APL you can assign into an array even though they are immutable (it will be copied behind the scenes) so it seems like it is an implementation detail you can ignore but wait that means dropping one character from the front copies the rest of the string in memory (slow) whereas in other languages trying to change a string at all is an error - compile time or runtime? You might think Prolog can do it if strings are linked lists but surprise, Prolog lists are immutable.
So if you read that sentence and move on, what have you really learned about the new language? In the context of this thread how would you Anki-fy the concepts immutable or sequence or string?
And I'm also saying that rote learning and background knowledge can hinder progress and require time unlearning, like the beginner needs to spend time learning. e.g. a mathematical sequence like "even numbers" can be infinitely long and the sentence probably doesn't mean that strings can have infinite characters in them. I guess, if you don't know the meaning of the words the sentence doesn't help you, if you know the words from a different context but don't know the programming language then the words don't help you, and if you already know the language then the words add nothing for you. Learning is impossible, Q.E.D ;-)
There's some grains of truth to aspects of the culture resisting individualism (which isn't inherently negative I don't think, as distasteful as that may sound to Americans), but not only is this a mischaracterization, it's also missing the upsides of having a population that all has stashed in their heads a whole shitload of math and science that enables them in all sorts of interesting ways.
For example, on a construction team, any single member is capable of more geometric reasoning than the same team in the usa (in my limited experience working with construction in both countries), making for faster, more accurate, and cheaper builds. Or, when bringing a software engineer up to speed with a new framework or whatever, I find they retain mundane details remarkably quickly, probably by having a well honed memorization method. That's really nice for when you're trying to think of how to implement something and basically the entire library documentation is just at hand in the noggin.
On the other hand, memorising things you do understand is a time saving measure at the point of memory access as well as something that allows you to play with concepts/ideas/facts in your head while doing anything else, which I've found to be quite useful. You do have to be selective about it, and software like Anki shouldn't be used to build memories for everything (for one, it can be so boring that you'll be turned off of SRS entirely if you overuse it).
They are not the same which is why they are two different words. For example, memorising first 1000 prime numbers is not same as knowing prime numbers. The former person will not be able to figure out 1001st prime number because it's not in their memory bank but the later can calculate it. Sure it takes time to calculate but it's not impossible.
Now, I'm not belittling memorisation. A baseline memory is needed otherwise one'll be wasting time and energy figuring out everything from first principles all the time. This is akin to rainbow tables saving time. But as with all things in life finding right balance is key. As you pointed out, it's useful to memorise things at work to save time and energy.
Try learning Spanish from scratch with a "bad memory" and let me know how it goes.
I am fluent in three languages. Learning words is the easy part, fluency unlocks when you are able to think, or feel, in that language. When you have thoughts that you cannot losslessly translate back to your native language.
Knowing Spanish words is not knowing Spanish. Memorization is the first and easiest 5% of the whole process.
I think this could be less likely if you're very specialized, but if you're a consultant or freelancer and have to work with lots of different technologies, locking down the differences and unique aspects for each could save a lot of time.
The use case you mention is more suited to a personal knowledgebase with good search capabilities and/or networking, like Obsidian, Tana, Roam, org-mode, whatever. That way you have the knowledge somewhere, you can search it (of course, this can be lossy - like writing good cards this requires writing good notes), and you can build up all the context you need.
I think the article misses the mark on the dichotomy here - it's not search vs. flash cards, it's owning your knowledge vs. relying on external, potentially ephemeral sources. Flash cards and spaced repetition are great for certain use cases (Anki is incredibly popular among language learners for a reason), but not for all of them.
I wouldn't describe my use of Anki as "rote memorization". Though certainly some people use it that way. There is a big difference between blindly putting raw and unfamiliar facts into an SRS, and using an SRS to remember things you have learned and understand. It's the second case that pays large dividends over time.
Also you dont need to write them out, you can still calculate it in your head "manually".
I think second student may have easier time to apply knowledge on things like 4 * 2,75.
If the test is designed to test understanding, then the kid with deep understanding will win.
By your definition, multiplying kid is faster at multiplying, but don't really know what he is doing outside of memorized situation. And at other is better at everything else.
But the question is, if school tests are at all related to reality. I don't think so.
Maybe your textbooks just don't distribute problems well enough, the curriculum changes drastically such that what you've just learned isn't touched on again before you forget it, or maybe you just don't have the time or material to consistently practice foreign languages for 1-2 hours a day. In these cases, the 10-20 minutes spent reviewing cards serves as a useful crutch in preventing that information being forgotten entirely, which undoes all the time spent trying to learn it in the first place.
That is exactly setup where anki makes less sense.
Anki makes great sense when you have a lot of time for that foreign language activity and are spending portion of it in anki vocabulary.You do it in addition to other activities.

I ask it a question much more naturally vs google - meaning less cognitive load and the answer it spits back is usually a result of multiple sources distilled down to the smallest amount of information - basically all the "fluff" removed. This means less time spent reading, filtering, finding the answer.
It's been wrong a number of times which costs me 5-30 minutes at a time, but I've severely benefited in time overall by orders of magnitude.
And I’m drawn a blank on the kind of professional stuff I’d put in here.
Generalized, cases where you can choose from one of a few options/technique and this choice is an expression of your professional opinion are good. What you memorize are the attributes of the options that you tend to make the choices on. It's hard to get across (and impossible if people don't want to believe it) the difference in speed/quality/accuracy that comes from having 3 attributes of 10 options at instant recall versus a few that come to mind right away and then more if you remember to try.
- Where are the log files for $service stored?
- What do the values of $one_letter_code in this message format/log line mean?
- What do I grep for to diagnose $problem?
More generally, when I find that I have memorised how to look something up (search slack for $foo to find the instructions, type $bar in the browser address bar to bring up the wiki page with the host name I need), I try to just memorise the fact directly, to reduce friction.
Anki was insanely popular in med school. It was certainly helpful for passing exams, but it's all stuff that can be easily looked up. It's all simple, basic facts.
It's far better to learn the theory, then fill in the details with easy reference.
Besides that, the original task Anki was designed for was language learning, and you can't have much of a conversation if every sentence requires multiple dictionary lookups.
I am curious to know how it can make my life better, and I'm not being sarcastic, but yours is a tall claim and I am very used to learn everything I do by myself.
What can Anki do for me in 10-20 minutes a day? Finding or preparing good flash cards is a lot of effort for someone used to ADHD-fueled information skimming to learn something breadth-first.
Several excellent physics and math students I worked with have never used spaced repetition software, but were excellent at their studies because they consistently solved textbook problems. For them, they got the "repetitions" (aka exposure to facts and problems) via solving more new problems from the book nearly every day. Later problems in the textbooks would provide review of previous problems. This method can be far more effective than spending too much studying with spaced repetition software (which I have done in the past), as the time spent creating new cards and reviewing cards that are due comes at the expense of time spent solving new problems.
Ideally, you can perhaps find time for both activities. But in my personal experience, I learned mathematics more effectively by focusing primarily on textbook problems (reviewing older material through new problems) and spending a very limited amount of time with spaced repetition, versus even a fifty-fifty split between a textbook and spaced repetition that I've experimented with in the past.
In the past, I also spent too much time in the past remembering phrases and vocabulary when learning new languages, and not enough time practicing listening, writing, and especially conversation. Certain skills can only be efficiently developed by directly practicing them. While spaced repetition software remains an essential part to my language studies, it is very far from sufficient (even just a couple hours of conversation practice per week over three months, got me much further than primarily focusing on Anki/spaced repetition for six months).
Spaced repetition systems like Anki (though I moved to SuperMemo about a year back) are vital to my daily studies, but I've learned far more effectively by treating these systems as a supplement to more traditional and tested study methods that rely on active problem-solving. For technical fields, these are textbook problems from books by well-regarded authors, and for languages, these are conversation practice and writing articles that I request feedback on (in particular, teachers in small group classes have given me great, useful feedback on my writing).
Things I use frequently I already pick up through repeated use, things that I never use eventually falls out.
But things that are somewhat relevant about that I find myself googling more than twice is a good candidate to Anki.
As a caveat, sometimes it can be hard to do this. If I randomly pick textbook problems, I have no guarantee that the new material will review the old.
Knowledge that is primarily conceptual (like almost all of math) generally does not benefit from spaced repetition. The learning involved is understanding -- a new concept may be hard to understand in the first place, but once you get it, you don't really forget it. Or you just need a super-quick refresher if you haven't touched it for a few months.
While knowledge that is primarily arbitrary-factual is the perfect candidate for spaced repetition -- mainly things like vocabulary, medical terms, and so forth. Just associating a largely arbitrary name for something. And indeed they are mostly useful for learning for exams. E.g. I used it to learn Chinese characters and could never have passed Chinese class otherwise. But on the other hand when I actually lived in another country that speaks a different language, spaced repetition isn't much of a help -- you learn vocab just by absorbing it day-to-day, like a kid does.
Otoh, certain stuff that are not particularly important need frequent repetition, eg learning a foreign language that you are not actively using.
I am considering using it for leetcode problems and questions.
In that use case, you are much better off reading content in that language and watching content in that language. Vocabulary memorization as isolated activity makes sense only as additional activity if you have additional time on top of that.
Really though a lack of spaced repetition on practising conceptual problems is just as noticeable as the lack of spaced repetition on factual learning. Very few fields are so perfectly structured that you get practices on their earliest levels by doing later levels and then working in the field, i.e. plenty of mathematicians admit they no longer do arithmetic well.
I've tried many times with other material, but I always get far more out of creating condensed notes and reviewing actual notes than quizzing random factioids in Anki.
I get that probably the idea is that creating prompts could guide me about which notes to review, but it seems easier to just review the notes. I think the people doing Anki are just putting the effort into making cards rather than into making notes. It would probably be nice if it were easy to convert notes into Anki but everything I've tried sucks and it just make taking each hour of taking notes into two hours of making notes and cards. I could have just reviewed notes for that hour. Closures are sort of okay but converting notes into closures is a bigger pain in the ass than it should be.
Maybe someone can make a LLM that takes some corpus of text and generates Anki cards of key points for review. Then I could just feed my notes in. But otherwise it really seems like a huge waste of time.
He says that spaced repetition is effective, but basic repetition of re-reading, re-watching, re-listening is not effective.
Spaced repetition with "active recall" comes out significantly more effective - instead of exposing yourself to the same material over and over, challenge yourself to recall the material at the time when you're on the edge of forgetting it; the active mental effort of doing that appears to fix information in memory much more effectively than reading or hearing it again.
A consequence of that is his suggestion that notes and review material should not be facts you want to remember, but questions that will prompt you to think and recall what you want to remember. "Writing questions for yourself makes you engage in cognitive effort, and the more brainpower it takes to recall a fact, the better strengthened that connection seems to get, according to the evidence at least".
The point being that if you are studying medicine the notes for review already exist and you just touch them up. You spend very little (if any) time actually creating them. I would certainly agree it's a waste of time to create your own notes in medicine.
I had lost all hope till I started using spaced repetition to relearn what I'd forgotten. Is it as good as doing textbook problems? No. But it's better than not doing anything. With spaced repetition I can have gaps of months at a time and can still get back to the material without having to start all over.
What pushed you to make the switch? Was it Incremental Reading, or some other feature/reason?
The software switch had its ups and downs. First, the downsides: a significant one-time cost included the time spent learning all the items from scratch, as the import of cards from Anki to SuperMemo didn't preserve the repetition history. Another one-time cost, though minor, was some friction setting up the software (it took an abnormal number of days to receive the activation code, which I eventually received after a follow-up; maybe the company had a problem with their system at the time).
Long-term downsides include the lack of easy image occlusion (aka, covering up parts of a labelled image and revealing just one label in separate flashcards). If I studied maps/diagrams with spaced repetition or anatomy like in my high school biology class, this would be a dealbreaker (though I suppose you could use keep using Anki along SuperMemo). In my experience, it's far easier to occlude images in Anki than in SuperMemo. Also, the Windows desktop version I use doesn't have a mobile version, which is a very significant downside. I'm now used to reviewing SuperMemo in the evening or when I think it's a good time, via software called Parallels to run a Windows virtual machine on a MacBook, but there's a lot more friction to starting a review session. To add to the friction, backups are a bit harder (though I've made it easier by setting up a custom keyboard shortcut to press the sequence of keys create a backup in a folder in cloud storage).
The main upside is that I do think (noting that I may have confirmation bias) that the flashcard scheduling really is effective and also more efficient. I no longer face significant numbers of very old reviews, and I do subjectively feel that I retain my cards better.
To add objectivity on effectiveness for accuracy, according to SuperMemo's data, I have a 97% retention rate on my French cards which contain a lot of very old cards, though I aggressively remake cards that become "leeches"; an 89% retention rate on my Spanish cards, which have much more newer cards; and a 93% retention rate on my mathematics/sciences/miscellaneous readings cards. Unfortunately, I didn't keep a records for Anki cards in comparison, and there may be other factors behind increased retention (if any) such as following better practices when making new cards [1]. I wish I had numbers for time efficiency, but I can confidently say that I don't dread spending time reviewing old cards (though once again, there may be some other factor).
On SuperMemo's other features: I also did try the "incremental reading" feature of SuperMemo, but ultimately, I borrowed some of the principles and stuck to a personal method of taking notes from different books, while switching between books (instead of only focusing on one subject a day) to help stay alert while studying the materials. There are also other features of SuperMemo for sleep tracking and task scheduling, but I didn't personally enjoy using them (I personally found that sleep tracking didn't account well for daylight savings, and I prefer other simple apps accessible by mobile devices for scheduling and task tracking).
To make a very long story short: I switched to try and reduce time spent during reviews, but ended up spending a lot more time setting up and getting used to the software. I didn't really mind the fiddling that much, as spaced repetition software was a sort-of hobby for me in the past, but for other people who'd just like to learn, Anki provides a far more direct way to try spaced repetition.
SuperMemo is effective for me now, as I don't spend much time at all fiddling with the software. But I'm not sure if I would enthusiastically recommend the switch to other people unless they're interested in spaced repetition software (and thus don't mind fiddling with it), and they also have some dissatisfaction with Anki in some way. In any case, with either software, I've found my studies to be more effective by treating spaced repetition as just a supplement to other forms of study that require active problem solving.
[1] Better practices included more strictly following Wozniak's twenty rules here (also relevant for Anki users): https://www.supermemo.com/en/blog/twenty-rules-of-formulatin...
Isn't it the case that only minority of students uses this software or flashcards in general anyway? I mean, of course it is possible to succeed without it, because overwhelming majority of students/learners are not using it.
If you define success as doing very well in the course (and remembering what you learn in the long-term), the idea gets more interesting because more people interested in these outcomes use flashcard systems. Anki is especially popular among medical students, so it's a tempting idea to consider that applying spaced repetition to subjects like mathematics or physics can also be useful.
To some people studying math or physics, the software can potentially be a nice aide, but in my individual experience, I understood and remembered concepts better by spending more time practicing problems and doing sample tests, versus spending more time using spaced repetition software.
Knowing him led to my impression that a decent number of math and physics students might have studied with spaced repetition without talking much about it, as he only mentioned it after he saw me studying with the software once. But in hindsight, I agree that it's more likely that math & physics students stick to the learning habits they developed earlier on—often through lots of practice tests and exercises.
Anki seems to be more of a natural progression for people in other fields like biology, where students might develop habits of using flashcards with software like Quizlet, where using software with better study schedules like Anki can be a natural progression.
Just under a month ago, I read about 'math academy' here on HN. One thing it does is sort of what it sounds like you envisage: surfacing exercises relating to concepts you might be about to forget.
Some ways in which it's different:
- Dependencies are core to the system. For example, if I am learning a music piece, I want to start by learning small sections and only move on to larger sections when I am good enough at the small stuff, eventually ending with a final exercise that tests my performance of the whole piece. A lot of knowledge/skills follow that pattern, but I couldn't find a way to make Anki or SuperMemo understand this.
- It's meant for both memorizing stuff and practicing exercises. I have tested it with your exact example (math problems from textbooks). It works fairly well, but it's at a very early stage (you can look around at https://github.com/trane-project/trane-math, but it still needs a readme). So it's doing the same thing as the students you mentioned. The difference is that the scheduling is done automatically. Review of existing problems and addition of new ones happen without requiring planning or tracking from the student.
- There's an emphasis on generating the flashcards as text files, so they can be shared. I don't understand why people insist of remaking their own flascards every time. If someone wishes to learn guitar, for example, it's my hope they just download some courses and start learning without spending any time redoing flashcards. This design choice probably makes it harder to write the flascards, but it balances out once the flashcards are done and can be passed around.
A quick question that I could not answer from reading the Github page: How married is the learning process to those "courses" you describe? If I have a topic X and start with 0 knowledge about it, could I use trane to learn it if there is no premade course yet? I assume to create a course about it, I would have to have quite some knowledge about the topic already, to be able to think of exercises and rate them in terms of difficulty/hierarchy.
They can be changed without affecting the exercises so it's not set on stone. So you could try to make a lesson for the initial topics and try to adjust the dependencies as you go along.
But the best way is to get help from someone who knows them.
A lot of software make empty promises around productivity improvements. Especially in education. Anki is one of those rare tools that genuinely 10x's you over your peers. I used it when studying Japanese and it was a massive help.
However, having used it for over 12 years to memorise many different things I have noticed one caveat.
If you're not also using what you're memorising outside of Anki, I feel like your ability to recall gets trapped within the context of using Anki.
For example, if you're learning Japanese vocab through Anki, and also trying out your new words via conversation and reading/writing, you'll rapidly learn new vocab AND be able to recall it anywhere.
However if you're learning Japanese on your own and not really conversing/writing, no matter how good your recall with Anki is, you'll struggle to recall those same words anywhere else.
The cool thing about Anki is you can also use pictures/audio. So if you're learning music theory you could memorise chord shapes/intervals. Or human anatomy.
If you use nothing but Duolingo you'll plateau very quickly. It's probably "okay" as a casual side spaced-repetition learning tool—when you're learning languages you generally want to pull from several different resources, and learn with different tools anyway. But don't make the mistake of thinking that Duolingo alone will get you anywhere.
I think this universally applies to repetition-learning, at least when it comes to languages. You need to "cross-train".
Yep. I agree with measured criticisms of Anki even while feeling the app is really useful if you use it well. Whereas Duolingo isn't worth bothering with at all. It's purely optimized to maximize engagement/revenue.
I have been following many of the recommendations on https://learnjapanese.moe/resources/. Most of them are language-specific, but perhaps you can still draw some inspiration from the methods and look for equivalent tools in your target language.
https://www.lennysnewsletter.com/p/how-duolingo-reignited-us...
Shows when incentives are aligned to shareholders vs users, that is the outcome you get
This also applies to practicing every single day: I find it easy to do a few Duolingo "lessons" as warm-up before delving into more in-depth practice.
Nowadays I would not use it for real "practice" at all. I use it to check my understanding for 5-15 minutes a day. If I make mistakes in Duolingo (eg. forming the plural, remembering the dative for a given grammatical gender) then I look these things up and study them.
I might drop Duolingo completely at some point, but for now I'm getting a non-zero amount of value out of it—I am increasingly looking into better options, though. I'm already looking Anki, and I'm sure there are some other language learning apps out there.
With nothing but duolingo and occasion "let's try to read or watch movie", my ability to read or understand went high in a way that would not happened without it at all.
If you only use Anki and don't do anything else, it's like building scaffolding on an empty lot, and then building more and more scaffolding without using it to build anything else.
I was wondering how much adding audio cards or "reversed" E->J cards to my routine might help. Are those variations worth the trouble?
The one caveat with Anki specifically for reversed cards is when you add a bunch of new cards or a new deck and it presents you the reversed card right after the basic card.
e.g. seeing the 幸せ -> shiawase (happy) card then immediately after the happy -> 幸せ card, sure you're going to be telling Anki this was an "easy" card, but that's much more about the immediacy than the level of recall you have.
For my purposes I actually have three sets of cards in my Japanese deck, one each for kana, kanji and english front card and the other two on the reverse cards (unless my textbook omits the kanji because of it being rarely used in the real world, as for some words).
> unless my textbook omits the kanji because of it being rarely used in the real world, as for some words
I have found this usually proves to be a mistake, textbooks and dictionaries pretend that you need far less kanji than you actually do. Lately I started to mine Anki words from conversations on Japanese twitter and I discovered that everyone casually throw around all kinds of kanji that are not on the Jouyou list and in words every textbook insisted were primarily kana.
I think it might be because modern IMEs have made it much easier to casually use rare-ish kanji. Technology has expanded the range of everyone's recall and writing speed, while the textbooks are still reflecting the world of 20 years ago.
I think you should strive to keep your decks under 15 minutes total. That means you can complete them in three 5-minute blocks a day. Any longer and I found I would A) miss a deck, meaning I had to catch up the next day; or B) try to rush through them.
I highly recommend trying to engage in conversation as much as possible. In my city (in Australia) I went to "conversation classes". Basically Japanese people wanting to improve their English would meet with Australians wanting to improve their Japanese. It went for an hour, half of which was spent talking in English, and half in Japanese. And if you can only speak a little bit of Japanese, it's totally fine, you can just speak in broken Japanese mixed with English. It was really fun! You'll find opportunities to use your new vocab, and it'll stick much better.
I do however maintain that for many skills it’s better to memorize processes over facts, and develop a more nuanced embedding with natural repetition intervals, rather than overfitting via excessive Anki-fication.
"summarize X as Anki cards". I found a reply above particularly helpful to even summarize anything at all.
perhaps someone could design software that automatically translates the article to the Anki cards as well. I'd love to collaborate with someone on such a project (as a data scientist)
When categorizing notes to be remembered, I think it's good to think in terms of memory retreival, not memory storage. In other words, not to become an "archiever", because you probably want to evolve your ideas by linking them together in your own unique way -- unique as dicated by your problem at hand plus your own idiosyncratic experiences.
"How to take smart notes" by Sönke Ahrens is a great book on this topic, admittedly more oriented towards a Zettelkasten/Obsidian workflow.
Disclaimer: going through my Anki decks is one of the 50 things on my 10-item to-do list. I don't get to it often enough. But it does work, and I now know how to memorize things I want to remember.
All too often people tend to their financial needs first, and find there's nothing left for themselves. No surprise most people die broke. Isn't it strange how their lifetime income just happened to almost exactly equal their lifetime expenses? Hmmm....
You might see where I'm going. Why are you giving the best of your time (rather than money) to everyone else, leaving nothing for yourself at the end of the day? Maybe start with just five minutes at the start of the day to pay yourself intellectually. If that works out, make it a habit!
I was able to get the second highest grades in the school, with lower than expected grades in only two subjects (and dropping one, further maths), because of Anki. Because Anki does not require understanding, only sufficient repetition, and I had a lot of time on my hands, I was able to continuously do flashcards for hours on end while maths work would have me struggling to stay awake within 5 minutes. I could remember facts without understanding them.
The exams were ~3 months after it happened, which gave me time to improve, plus during the actual exam a combination of painkillers, extra time, rest breaks, exam technique, and adrenaline allowed me to put together a plausible answer with the disconnected facts I had learnt in the months preceeding that I just about got the mark. As a sidenote - it's quite incredible how adrenaline can temporarily improve brain injuries, with the downside that the moment it went I was completely exhausted.
Every subject bar maths I got the grades I wanted or just below, because Anki allowed me to memorise without learning.
(These subjects were: Maths, Physics, Chemistry, Biology, English Lit, English Lang, History, Computer Science, Digital something, Creative Media Production (didn't do exam), Further Maths (dropped).)
Now, I would prefer not to revise using solely Anki, and I think the fact a braindead student with memorised facts (and good exam technique) was able to get good grades says a lot about the British education system. It also says a lot about Anki, and just how effective it is.
Side note, because I'm tired of hearing drivel on HN:
My life being (permanently?) ruined was entirely preventable, all it would have taken is a little less empathy, a little less second chances, for violent barbarians who damage everyone around them. When people preach empathy they forget about the human cost of allowing inherently violent, destructive people to continue their actions.
If you're one of those people who thinks grammar schools are bad, restorative "justice" is the future, and we should prioritise those who hurt and destroy over those who want to learn and build: Your actions and your ideology have ugly consequences beyond your selfish delusion of making the world better through being nice and kind and the power of love - that belongs in novels, not policy.
The best schools were ones that back up and support their teachers in disciplinary action (usually detention, buddy-class systems and behavior contracts which are all pretty effective if applied consistently and supported by management).
After learning one language in school and a few others ad hoc on my own I gave this method a try.
I quickly gave up, though, once I discovered Dr Krashen's work on comprehensible input, and how boring and time consuming creating and studying Anki is.
Dr Krashen's work says that we learn language when we understand it. I.e. when we receive input at our level. There are quite a number of Youtube channels that claim to teach through this method, but many of them still resort to drills, themed vocabulary, grammar etc that are all pointless in the CI method.
The best one I've seen so far is Dreaming Spanish.
What's so cool about the CI method is that the spaced repetition is built in, implicit - if you're getting input at your level you will be getting repetition.
Children's shows are a great way to get input. Many countries have TV apps on iPad and can be viewed free with a VPN.
As an experiment I had my daughter only consume German media (living in Sweden) för a few years and she can now speak better German than I can, and I have never corrected her. She has broader and more modern vocabulary, naturally.
As a beginner, appropriate input was enough to care of "spaced repetition" on its own, since children's media constantly rotates over the same small set of vocabulary. But after I improved past the ~2000 most common words or so, it happened more and more that a word I recently learned didn't appear again in my input until it had already been flushed. The probability that I would actually learn a new word for good progressively decreased as I picked the lower-hanging fruit, which is the cause of the dreaded "intermediate plateau".
I gather Anki pushes out the plateau much further: I have heard that it starts to feel Sisyphean to learn new words with it around the 15000-20000 word mark instead.
Especially at the very beginning, I find learning the first 500 words as described in "Fluent Forever" very helpful. Going through that before starting with the course makes the experience much easier.
I totally agree with Krashen's theories, but using Anki is a secret weapon here that puts the process on overdrive (e.g. reading on Kindle and then later going through words that I checked in the Kindle dictionary and adding them into Anki).
Also, it's essential to retain the knowledge, e.g. if it's a language that you don't use daily.
5 years and 30'000+ cards later, I find Anki indispensable in learning anything which requires memorisation. Thinks I have to learn for work, for hobbies, certificates, improving my vocabulary in languages I care about. Basically, every fact I care about strongly enough, goes into Anki. If not enough, goes into Obsidian.
You have to learn the high frequency words/phrases in context (forget 500 most common vocabulary lists -- those don't work). As a child, you do this naturally.
However, there are certain situations where Anki helps. I find it's with words that are useful but don't occur frequently enough to pattern match. For instance, the word "ad hoc" in English -- it occurs in professional speech, but not quite often enough for you to remember what it means in context. This is where Ankifying can really help.
Ankifying commonly confused words/phrases can also help. For instance, in English the word "put" can be used in so many contexts, and many of those contexts don't occur frequently, but can be the source of funny mistakes.
"Put up (with)" and "put out" and "put in" all mean different things in different contexts. Embedding context in your Anki cards will help you recall these contexts.
Be careful with this, perceived self understanding doesn't reflect real understanding.
For other subjects (and CS, too): demonstrate mastery with teaching others, producing something with the concepts learned and get feedback.
This way one can test true learning. And, even when tested this way, Spaced Repeatition really helps. I am speaking from experience.
When you are in a place where you can immerse yourself in a proper environment, like a college or work- where you hear terms and their usage regularly, learning becomes easier.
But when your environment is cut-off from the buzzing world, or everyone is doing ML and you want to do Cybersecurity, you can fake immersion using Anki. A good part of physical immersion can be replaced with using Anki.
At one point I realized that my capacity for learning new items for a particular topic is limited to a few items per day. Any more than 2 or 3 and I struggle to retain the information. So, for example, trying to learn 20 words in Chinese per day is impossible without spending multiple hours on it.
The trick, however, is that I get around this by having many items from multiple topics, instead of many items from a single topic. Instead of 20 words in Chinese, I learn 1 word each in 20 different languages. Surprisingly, I have a much easier time with this and don’t need to spend much time on it in order to retain the information. I don’t know why this psychologically works, but it does. And while learning 2 or 3 words a day won’t make you fluent anytime soon, it does add up over time, especially for topics that you aren’t in a hurry to learn but would like to know on a slow timeline, in a year or two. For example, learning the Japanese hiragana/katakana or the numbers of all the US presidents.
However, this proved to be somewhat unwieldy logistically as I had to open 20 different PDFs, download audio for each word, then stitch it all together daily. So I created a little web app (stitched together from some WordPress plugins, actually) that allows me to import learning materials and then display 2-3 of them per topic on a single page, each time the page is loaded. I just visit the page once a day and add the items to Anki.
This was all a bit complex to set up, but if you enjoy learning new things and want an efficient system for adding stuff into your brain, I recommend making something similar.
I think most people make “language learning” a heavy task that seems insurmountable. In reality, once you understand the basic sounds of a language, it can be as simple as learning a new phrase everyday. Just think of it as learning the names of capital cities or elements on the periodic table: a lot of information that is organized into patterns.
No, you won’t be fluent quickly, but it is absolutely beneficial to know “hello”, “thank you”, “where is?” and 100 other phrases in a language. Or in the case of Russian or Hebrew or Greek, it’s awesome to just be able to read the alphabet, even if you don’t know many of the words.
Last time I checked on this it was like a lot of effort to put on and got discouraged to build my own decks to improve my italian. I was expecting anki decks to be constructed easily, in its most basic form from plain text files (html, markdown, etc) with references to maybe resources (audio, images, etc) just from a filesystem directory but is not that simple.
I can't recall the name of a Python tool that allowed you to create decks programmatically but I found it way too much effort to use it and I couldn't find other good alternatives (maybe this has changed recently, don't know).
Does anyone recommend a good, simple and straightforward tool to create decks/cards? (I'm using FreeBSD).
If I'm not mistaken it's also possible to import CSV data directly into anki without the intermediate Python script
> "...You need to pass a model_id so that Anki can keep track of your model."
At that time I wondered myself: "Why on earth do I need to keep track of a model id for an anki card?" then quickly move forward on the docs without paying too much attention and finally put it aside...
That said, making decks is extremely tedious. It’s better than a premade deck for learning language vocabulary, but it’s time consuming.
You shouldn’t make vocabulary cards programmatically. If you’re going to invest time into learning a card, you need to be absolutely sure that it’s correct. Otherwise you’ve wasted your own time.
When I was using Anki daily, I’d reserve about 20 mins or so in the evening to input new words.
Honestly CSV import is the way to go. That leaves you with how to get cards in. That depends largely on how you are working with stuff.
Some bespoke options include:
- The Kindle dictionary lookup history is an SQLite file on the kindle. Scrape that and pull it out
- Write a CLI command to lookup words in some dictionary website and stick that somewhere
- Just have a text file open somewhere where you paste words, and then you do the lookup later.
I think there's a lot of ways to make things easier, especially if you're working with another language with an open source dictionary. You need to do some one-time elbow grease to get it in, cuz what people want is different.
Another thing you can do if you like just going wild: just download somebody else's card deck. You can set things up to show you (for example) 10 or 5 or even 2 new cards a day. You will end up being shown a bunch of new words. You can just absorb those over time and see how that helps.
I'm building https://github.com/AlexErrant/Pentive/ which is basically Anki + Github + Reddit; people can optionally upload their cards for others to download/fork, and the most popular cards rise to the top. It's FLOSS, offline-first, supports plugins and p2p syncing, and is very much a WIP. My proof of concept is almost done though, which demos the critical technologies in a secure way.
There's a number of Anki alternatives such as https://mnemosyne-proj.org/, but Anki has an active collaborative community, as opposed to most of alternatives, as far as I know.
It's like slowly uploading information to my brain for permanent storage.
What I have used it for:
Memorising how to identify plants and their latin names
Memorising the technical terms for different morphological features of plants so that I could efficiently use a vegetative identification key without constantly flicking to the glossary
Memorising foreign language vocabularyI used Anki for this when I was in a management position that involved meeting with many people, often just once or twice each, across my very large company. It was nice to be able to greet someone by name in the cafeteria six months after our meeting, and ask how such-and-such project was going. I'm sure some people already remember names, faces, and context effortlessly. I'm not one of those people. But I always appreciate when someone remembers me, so I was willing to work to do the same for them.
I stopped doing it once my work universe got a little more stable, and life's daily encounters were themselves the spaced repetition I needed to remember everyone.
We could do this all day. The fact that there's something better one can do doesn't negate the benefits of the former.
I used it so much it has become sort of a "Corgnitive Primitive" where I put everything there: Questions, Facts, Interesting Things, Calendar Events, Prompts, Writing Tips, Mutate-this-idea, Mood Controls, Historical Events and Dates, Todos(Spaced Repetition Productivity?) etc.
One example would be: I've grown from a (...) to a (...). I complete the (...) with something from my current mood. This is good because I'm accumulating "Writings" from myself to publish a novel, manga or story later on. When I need to write something then I just consult my notes for everything I have written at that moment.
I'm currently working on a tool[1] that has built-in Spaced Repetition(I made my own algorithm and don't use SM-2[Anki's Algorithm])
While this type of article is almost cliche at this point regarding someone coming across the memory limitations and the power of anki for the first time, I really think the case for anki is exaggerated with "important ideas".
Anki is great for preparing to go on jeopardy or being in say med school. It is not really needed for lifelong learning.
https://en.wikipedia.org/wiki/Zettelkasten might be a better approach but even then it is debatable how often you'll ever actually use it once the novelty wears off.
Anki is a tool to be used, not something that needs to be applied to everything.
Here's what I'd like: while I'm reading a (PDF) book, I want to highlight some text (and maybe manually tweak it a little) and have it converted into some "Anki card" format so when I want to review the contents of the book later, I can use Anki for it.
Any ideas?
Then turn it into an Anki card, preferably with clozes.
Half the benefit of Anki is making the Anki cards in the first place.
You also don't normally use an srs flashcard program like anki just when you want to review a book, you use it every day.
A prominent example is when I was working through a deck of japanese hiragana and katakana, I was doing my cards at a moderate pace every day, and I just kept mixing them up, even when I was repeating them in short succession. After a few very frustrating weeks of this i ditched anki and started trying to write out the whole table from memory and checking for mistakes after, this strategy proved so successful I only needed three sessions for perfect recall.
I used anki a few other times with similar results. I know the idea of learning styles is disputed, but this app just doesn't appear to work for me.
I like reading tech books which are not directly related to my job as SWE. E.g. I'm not working with Bitcoin or ML, but found those books very interesting. However after a year pass - I barely can remember little bits which I've found very interesting when read the books.
I think adding some facts to Anki cards would help me to remember those certain things. I guess difficult part would be to detect the fact which is worth to be added as a card. Since while reading the book - these things seems obvious. Going to try anyways.
The time to memorize something is supposed to outweight the time you'd need to look it up. Say the target is five minutes - in that case, it's important to follow the Pareto rule as well, and to discard any cards that take you more than that to memorize in total, including the time you recall them. In practice, it means discarding over 20% of cards if possible, to learn 80% that are easy to remember.
(Cards added above the new card limit go into a queue for future days automatically.)

I was on a boat and learned someone's name, and said to her "I'll try to remember it, but-" she cut me off and said "stop telling yourself you're bad at remembering names, everyone does that, then they can't remember names!" I'm aware of the self helpy concept of self actualization and all that and couldn't help but internally roll my eyes a bit, but it did make me think: damn, I really am bad at remembering names, seriously bad, worse than anyone I've ever met in fact. Someone will approach me at s grocery store, call me by name, and start reminiscing with me about things we did together that clearly were fond memories for them, and throughout the whole conversation I'll have no memory of the person's name or any of the things they're talking about. This has happened greater than 20 times in my life, so I was worried I maybe had early onset Alzheimer's or something, but two psychologists have told me It's probably just a symptom of my severe ADHD.
So I put my foot down, fuck it, I'm not forgetting people anymore. I made an anki deck on my phone with three fields: picture of their face, name, and basic info about them, maybe times we've hung out etc. The "question" side is their face, answer is name and description.
I started throwing in people immediately after I met them and backfilling people from Facebook events and Line chat groups. I'd lift their profile pics or whatever else.
It's pretty fuckin creepy to be honest and if I ever get caught reviewing the deck I'll be really embarrassed, but it's working extraordinarily well, and I haven't had the far more embarrassing moment of forgetting that the person I'm talking to went to a baseball game with me once or whatever. Some might say "well clearly that person and event just didn't matter to you if you don't naturally remember them," to which I say I will genuinely forget entirely what I did yesterday sometimes. Something's messed up with my memory and anki is able to fix it, just like daily outline journaling every night has fixed the thing where I'll just forget an entire day.
One possible way to get there on mobile: 1. Start reviewing a deck. 2. Click the gear button. 3. Choose “Custom study” and select one of the options. 4. If studying tagged cards, go tag some cards via the Browse view.

Someone should make a match three or other addictive game that periodically shows you flash cards instead of ads.
