This is a few days worth of materials to read. If anyone finds it overwhelming, I recommend you read this comic that teaches you the basics of idea behind spaced repetition <a href="https://ncase.me/remember/" rel="nofollow">https://ncase.me/remember/</a>
I've tried spaced repetition systems several times. The problem that I always discover is that I don't really have stuff that's worth memorizing. Things that are actually important I remember without trying and for the rest of the things, doing daily card reviews starts to feel like a pointless chore after a while.
Dropping a product recommendation -- my favorite spaced repetition + notetaking + learning app: <a href="https://www.remnote.com/" rel="nofollow">https://www.remnote.com/</a><p>I'm not affiliated, just a big booster. For those familiar with Anki it follows the same conventions. It has an excellent system for managing cards. Adding cards is as easy as writing a bullet point: [front of card] == [back of card]. They got the ergonomics right and clearly know the space very well; it has the right keyboard accessibility and shortcuts and navigation. It supports the basics you'd expect like cloze deletions (fill-in-the-blank), image occlusion (cover up parts of an image). It manages assets like PDFs and images. It uses FSRS (the best SRS scheduling algorithm atm).<p>It has the best (optional) AI integration into a product I've seen except for the usual code-generation suspects. I'm learning spanish and can type into a bullet point something like "el vaquero ==< [tab]" and have the translation automatically generated for me into a forward and reverse card. I'm learning math and can cloze-delete parts of latex equations; the AI can very frequently generate excellent and accurate latex equations, which I can make small edits to as I'd like. These kinds of bonuses make taking live flashcard-based notes during my spanish tutoring sessions and math-based parts of classes feasible.<p>It's less low-level configurable than Anki and more "works out of the box" with a smaller extension system. I've had enough of trying to fiddle with Anki. Overall just excellent -- I'm not affiliated in any way. Development is very fast. Release note videos are incredible, minor updates occur ~weekly. I've run into a few bugs, especially when I was traveling overseas where internet isn't strong, but overall very pleased with it.

I started a new Study Set from scratch, and add new words to memorize every lesson.
Liking it so far!
His article <a href="https://andymatuschak.org/books/" rel="nofollow">https://andymatuschak.org/books/</a>
inspired me to build <a href="https://readboost.io/" rel="nofollow">https://readboost.io/</a> to embed Q&A and SRS into ePubs. Might be buggy still, but I personally found it quite useful!
I very highly recommend a blog post by this same author: [How to write good prompts](<a href="https://andymatuschak.org/prompts/" rel="nofollow">https://andymatuschak.org/prompts/</a>). This post made spaced repetition click for me.
One of the barriers to adoption (to my adoption, anyway) not mentioned in the site author's list:<p>I am one of the least qualified people in the world to write cards for a topic I am learning. I would quite likely create cards that would help me memorize inaccurate information effectively and efficiently. I'd rather not take that risk.
I use a variation of an SRS for storing notes about what I've read (as well as using a regular SRS for regular SRS stuff). I chunk notes I've made from books I've read (things like Psycho-Cybernetics, 7 Habits, Iron John, etc), and review 3-4 a day, and having read them I'll clip anything that's particularly salient into "daily review" and then push back the notes for however many days, weeks, months, I think. This has worked well for me over the last 15 years or so I've been doing it.
