Who chooses the videos? It seems ... opinionated. For example, under 'Physics', we have "The big lie about carbon capture', 'Why (toilet) flushing isn't for everyone', 'The scientific basis for miracles', etc.

Yeah it’s not ideal yet the suggestions under each category I just YouTube’s own category labels so often it didn’t give the best results, but it’s something I’m working on!

When I saw Anki/Duolingo in the bio I assumed it was for language learning, but this is a great idea! I too often watch these kinds of videos without really retaining a lot. This is a perfect complement to turn infotainment into time well spent, or at least, less wasted.

Same! Maybe someone could do some language learning on top of all the videos we consume on YouTube?

What algorithm do you use for spaced repetition?

I have a fairly simple implementation of the SM-2 algorithm, and just making the assumption that if you answered the question correctly then you have “perfect recall”. This isn’t exactly correct but I have been using it myself and seems to still be pretty nice.

But for the next version I want to use something called knowledge tracing to determine an estimated level of recall to then change the spacing

Yes!! I definitely spend a little too much time on YouTube myself, would you mind sharing what kind of content (categories) you watch in a pm? I’d love to get some better ideas of what kind of material to tune the question generations on

I want to make flash card form everything I look up this way.

Any particular type of content you’re thinking of? I’m currently working on adding podcasts since they’re pretty similar to YouTube videos, but I’m sure with some tuning I could see if it works for other things

Podcast is definitely one. But I’m not sure how one could get the real salient points out of some of the philosophy podcast I listen to without listening carefully the first time and writing them down.. Another would be for example when I ask Chatgpt how to do something in nvim.
