I don’t think they’re attached to YouTube too rigidly. (Well, I hope at least.) In theory this should work with any platform that provides subtitles. But I think if YouTube falls, or blocks their API access, they would just start hosting the videos themselves.

> In theory this should work with any platform that provides subtitles. Streaming platforms can vary quite a lot in how they choose to distribute subtitles. I've worked with scraping subtitles from both Youtube and Netflix and I will say that these platforms distribute subtitles very differently!

Yes! It will take some time to write a scraper for another platform (probably not Netflix haha), but after that it’s plug-n-play.

And of course, if they decide to host videos on their own platform, they can just import subtitles from srt/vtt/ass which should be easily possible with some open source library.

Your app is simply awesome. I've playing with it for a bit and I can see how this approach would make traditional homework much more engaging. Also, the LLM doesn't care about the language used in the responses, so my understanding is that localizing the content in different languages would be very straightforward.

This is, I think, particularly important for kids in most parts of the world as a majority of the internet pedagogical content is English-based. Or for people like me, that struggle with that language when talking about topics outside the tech industry.

Congrats for your project, I'm sure we share the same positive view about the future of learning :)

Nice work! How do you verify correctness of the generated exercises and explanations? To me this looks the biggest risk in becoming a user: what if my _teacher_ teaches me subtle nonsense that I cannot easily detect since I'm learning and unfamiliar with the material (even if it's only in the 1-2% of cases)? Human teachers make mistakes too, but an LLM cannot _understand_ that it made one... So.. how do you solve for…

they dont verify, they just present a LLM app and the user suffers if the information is not correct. however most of the time it is correct but sometimes it is not. one way to verify correctness is to ask a bigger model like OpenAI o3

I’m not sure how the solution to “LLMs lie” is “more LLM”. I’ve personally had o3 tell me stuff like: “I ran this query against version 0.10 of DuckDB and verified that it works” when the query contains functions that don’t exist in DuckDB or “this version gets better PageSpeed Insights results” when I know it can’t check those. It happens surprisingly often and it’s super obvious. However, it’s made me seriously wary of the information that it gives which I can’t verify purely based on logic.

congrats on the launch!

i opened a random lecture (MIT 14.01 Lecture 19: International Trade: Welfare and Policy)

a- i tried an exercise without watching the video, and then clicked on 'watch' next to the question, i expected it would take me to relevant portion of the video instead it played it from beginning.

b- i used the ai tutor and asked 2 random questions, instead of giving me an answer it prodded to provide more detail. this might be an intentional choice to ensure learning, however i personally prefer chatgpt's style where it gives me some information and then provides more angles to pursue.

i also asked the tutor about batman, here's the response for reference:

tell me about batman That's a good start, but your question is very broad. When you say "tell me about Batman," are you looking for information about the character's origin, his role in comics, his significance in popular culture, or something else? Try to narrow down your question a bit.

For example, are you interested in: - Batman's backstory and how he became a superhero? - The different versions of Batman in comics, movies, and TV?

Thanks! Yea the watch button should do that, we added 14.01 before that feature but will fix asap.

And yea probably thinking to do a guiding mode (as you said, often better to have the tutor guide you through step-by-step instead of giving you the answer right away) and a straightforward answer mode for the tutor. Or if you have any other ideas.

Not a bad concept. I already do something similar

I already use LLMs to quiz me on books that I'm reading. The current book I've been studying is "Computer Networking: A Top-Down Approach (8th edition)." Obviously since it is a text book, there are homework problems and other discussion points. However; it's also fun to ask grok/chatGPT to quiz me on previous chapters and correct my answers.

There's plenty of conference talks posted on YouTube that I've watched over the years. Next talk I watch I will probably test out being quizzed by LLMs.

Is the course creator being impressed the most important metric? Are there other more concrete metrics you are able to use to determine quality from the perspective of a student? I am curious if you are using any methodologies from the digital learning space like knowledge tracing to help ensure that learners are actually retaining knowledge and improving over time or knowledge mapping to understand the gaps that mig…

At this stage it seems like a good metric since it's the creator's content. We're adding a feature for question feedback from users, so they can like/dislike/report questions, but very open to other metrics if you have any ideas. Yep—also in the process of adding learning paths for certain subjects, so you can go from an introductory course to more advanced topics and fill in gaps in understanding. Agreed: our missio…

I made a comment a few weeks back that goes over a lot of the research I’ve been reading in the area: https://news.ycombinator.com/item?id=43543335

Also happy to chat more, I find this space really interesting!
