I use Anki to learn French, Chess openings/tactics/techniques, to unscramble letters for scrabble, for Pub Trivia... The options are kind of limitless. As a mid-30s guy who has well passed the neuroplasticity of his teen years, it's a godsend for me. To echo the author's thoughts though, I can't prove empirically that I learn more effectively using Anki (or spaced repetition) than other methods... Only anecdotally. I…

I'm glad the article acknowledges that flashcards are just one small part of learning. When I first got into spaced repetition, first with the Mnemosyne Project and later switching to Anki, I discovered that the efficiency I imagined was partially illusory.

* Memorizing things often takes much more time than learning things naturally as you use them because it takes extra time out of your day. * I often lacked the associations that would normally help reinforce a concept or fact because I used brute force a-single-super-simple-concept-at-a-time memorization instead of more natural methods where context helped me gain a better understanding. * Breaking things down into very narrow, simple, one concept cards is more difficult than I imagined. * Creating mnemonics is really helpful but can be time consuming, and you don't know which cards where you will need them until you repeatedly forget those cards. Someone on HackerNews about a year or two ago recommended using AI and that did help a little, but it didn't take long before I realized that the AI created mnemonics feel so similar and less connected than time tested mnemonics that I find them less effective. * Since brute force memory is slower I often learn slower, which is less efficient than learning a groups of related things together at a pace where the concepts together give you a better understanding than learning one at a time. (Sometimes you need to slow down because your not getting the concept, but going too slow is less efficient also.)

I still use spaced repetition but I realized it's not the amazing revolution that I first imagined that it would be.

> Some people also use LLMs to generate flashcards. And of course, the result will be those impersonal, mediocre cards.

> I won’t say LLMs are useless for this. But from my trials, I get about 1 card that’s useful to me out of 10, and even that 1 card still needs rewriting.

I don't know the specifics of how the author tried to do so, but from what I've seen the majority of attempts are, let me drop a chapter of a textbook and say "make flashcards." If that is what we are talking about, then yes, LLMs are useless.

In my mind, though, this is sort of like looking at the very first GitHub Copilot LLM autocomplete from a couple of years ago and concluding, yeah it's nice for one-liners, but it cannot write an app.

If you create a framework around your card-creation AI so that it can use tools, and verify its work to ensure common card-creation pitfalls don't happen, you can get pretty high-quality cards. In my experience, you go from a 10~20% hit rate to a ~90% hit rate, which in my mind is good enough. I got to ~75% quality just from a two extra LLM calls that would assess a potential card against a standard set of rules (adapted from [0]). There are huge Pareto gains to be had here.

I've generated thousdands of cards over the last few months this way. I let the AI add it directly to Anki via AnkiConnect. Then, if when I go to review I find a card that my AI created and I don't like it, I just delete it.

Removing the limitation of card creation is really quite compelling, and I think the area is still highly under-invested in. Would be cool to see a generic framework evolve that one could use. For now, I've been using a personal fork of clanki [1].

I once took a psychology course with my girlfriend at the time. She and her pals would be up all night studying with flashcards. I'd just walk into class, learn about it, never study, and get A's on the tests. When they asked me how I was doing it I explained that I'm there to learn understand the topic and I don't give a damn about the test. So I just let my curiosity lead the way, it causes me to ask questions in a…

You just described a terrible strategy for wrote memorization.

You did better than they did because the test didn’t test wrote memorization.

I used anki for learning japanese, and what I noticed while is that, at least for me the act of reviewing flashcards became a burden itself. It was not fun nor pleasant. I’d go back to using Anki if i’d know how to solve this.

Practicing your retrieval is actually one of the best ways to retain knowledge of something. Flashcard programs like Anki are really great because it identifies where you need more work and drills you on your weak points -- it feels awkward working constantly on your weak points, but you get quantifiably better results with the flashcard method it uses. Some people criticize flashcards as optimizing for rote memoriza…

My problem with Anki is that it's very, very inefficient. It will take much more time and effort to memorize the vocabulary words you learn, and losing those words is very quick. It's much better to use SRS with actual and varied sentences.

You know you can just…create Anki cards with sentences, right?

Anki doesn’t force you to make cards with vocab words in isolation.

I don’t know…I think even if someone was really interested in something like organic chemistry or biochem, unless they had a very very abnormal memory they’d get wrecked on an exam without studying.

I used SRS when studying for OChem and got the highest grade across all sections my prof was teaching.

> Most of my cards are handwritten by me and accommodate my brain.

I'm guessing from all the talk about Anki that people are missing this part. I think these frictionless, digital replacements for note cards are solving the wrong problem. You're never going to spend more time on a given flashcard, and better absorb the information on it, than the first time, when you're sitting there making the thing. Making this step as brief as possible is a bad idea.

I think deliberate practice is what's really core to improving any skill, including memory. Spaced repetition is an effective way to review things but its biggest benefit is a process that's easy to be consistent with. Somebody else can have equal or better performance with other technique but just like dieting, it doesnt matter as much what method you use as long as you stick with it.

I feel like the actual core mechanic at improving is the actual act of "recall", it doesnt matter what you do if its a form of recall it is effective and very awkward in practice because you just sit there waiting for your brain to do a mysterious thing

"Active recall" specifically (aka the testing effect [0]), as opposed to passive recall like rereading.

It doesn't but it also will not create a different sentence to you to practice a word. I tried this (use sentences instead of words), it sucks: you spend more time per card, but you learn less efficient, as you learn not just a word but all the hints coming from the same sentence.

I wrote my own program 2 years ago, that generates new sentence on each review using AI (at that time I used Anki as scheduler). That was fun and quite effective as far as I can tell. I would recommend others learning language past A1, maybe A2 level to do the same. This day you don't need Anki for this, just use one of FSRS libraries for scheduling.

When I was a kid I used flashcards to memorize the multiplication tables up to 12 and it allowed me to do very rapid mental math from that point on, and I still can to this day. It was useful for math quizzes and tests in school but it's also useful for life in general. Going up to 16 might be even better.

I use the Livio English Dictionary to look up words when I read on my tablet and I noticed one day that it keeps a search history, and I got an idea to make an Anki flashcard collection consisting of all the words I've needed to look up while reading. Despite being an obsessive reader my entire life I still regularly encounter words I'm not 100% certain about. Reading itself has spaced repetition built right in, assuming you quiz yourself and then follow up with a dictionary.
