It seems a lot more effective than spaced repetition, but also a much higher level of commitment and a higher learning curve. It's sort of like using a power tool. I haven't tried it, but this is a good reminder that I should.
This is a tool meant to help with incremental reading, with support for generating Anki flashcards.
I'd love to have something for it on mobile, because that's where I spend all my reading time, and that was one of the main advantages of Anki.
For example, if you have a list of 50 PDFs and you want to incrementally read them, Polarized doesn't have a way of scheduling when you're going to read all 50 PDFs. Supermemo, you don't have worry about that. IMO, that's the key feature of Incremental Reading.
I can chuck dozens of articles at a time into Supermemo, and do not have to worry about forgetting to read them. They'll show up in my reviews over time.
