SRS systems are a good start, however they typically only utilize flashcards and treat all information the same. Where we are starting is looking at the type of knowledge that's trying to be retained and building a solution for each one.
Without giving to much away, a SRS flashcard is quite good at helping you remember a vocabulary word, or a single fact. These systems break down quickly if you have a multistep process (like closing a sale) or a tree of conditional steps. We have solutions for each of these and we're learning a lot of interesting things from our early customers.
The entire system is built around creating information that is highly memorable, so from first view to latest review we're optimizing the learning path.
Are there studies you use to inform your secret sauce? Are they recent?
I ask as someone who's been building a personal knowledge base of sorts of which one key component is Anki / SRS.
As a daily Anki user, this seems interesting though.
Happy to talk more about this and talk go over what we're thinking. brian@hickorytraining.com
The OP made it sound like Hickory is automatically generating cards based on what a user reads. It also sounds like Hickory is doing more analytics. Of course, Anki is open-source, so it could be augmented to do these.
