Generative UI for education

Thank you very much! That’s strange, we’ll look into it. Really appreciate you reporting it.

The lecture description language isn’t public at the moment. It’s a core part of the technology we’re building the company around.

Also, if you’d like, you can share the video as a public link by clicking the share button!

We think videos are special. There is a reason why Khan Academy, Coursera, etc. are essentially video libraries. A lecture video is a recording of a teaching performance, a form of presentation where someone explains while controlling what you see and when you see it.

Also, you’re not chatting with the transcript; you’re chatting with the video. The AI has much more than the transcript in its context. See this, for example: https://academa.ai/lectures/diffusion-models-learning-to-den...

And in the coming months, we’ll make the answers themselves real-time videos, which is kind of trivial for us at this point. We’ll ask the LLM to answer by writing code, and our software will render that code and show you the response directly as a video.

Thank you!

Actually, the economics are quite good.

We’re not using video generation models. We ask an LLM to write the lecture as code, then render it deterministically with computer graphics and TTS.

So the main costs are the LLM call, TTS, and some cloud GPU time for rendering. That ends up being much cheaper than generating long form video directly with video models.

You can attempt to do it, but you'll see that it won't work. We've built the underlying "lectures as code" technology to make this work.

You just said in another comment that you use Claude Opus 5 to generate the video in a single shot. What about it won't work?

We ask Claude Opus 5 to write a specific kind of source code that only our proprietary software understands and can render into a lecture video with computer graphics and TTS.

Without our system, there isn’t really an equivalent target language you can ask the LLM to write. Manim exists, but you won’t get videos like these by simply asking an LLM to generate Manim code.

Claude Opus 5, with high thinking, generates the video in a single shot.

The one that asks questions at the beginning is Gemini Flash 3.7.

Coding, graphics, all seem to have very defined background data for an LLM to base their decisions on, test, and even when I correct it we're all on the same page. Seems like there's lots of room for AI productivity there.

What I find funny is that approximate to computer graphics are video games. When I ask AI about a decision available to me in a video game AI completely fails, OFTEN. I assume all the forums and changes made to a game over time might be quite confusing for AI. But I've also seen it completely make up characters and decisions and weapons and so on about some very clearly defined games and paths. It's an interesting dynamic.

Sorry about that paywall. We've made the AI chat free up to a certain usage limit, so if you're interested, you can give it a try now!

Thank you for letting us know.

Thank you :)
