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 l

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

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 lang

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

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.

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.

On consumer devices, AI communicates with us through speakers and screens. Screens are the richer medium, so most consumer AI innovation will happen there. Computer graphics will have enormous applications because they are directly controll

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!

We are fully compatible with Manim CE. Our goal is 1:1 API compatibility, so people can continue using the API they already know. We never intended to use 3Blue1Brown's name in a negative or misleading way. We simply wanted to communic

You can use the editor however you like without signing up. The examples are simply sample prompts for the AI, but you can paste in any Manim code to editor from ChatGPT or anywhere else, and the preview will render it instantly. Downloadin

Thank you! We simply mount the entire app inside the landing page, but rotate and scale it down. When the page opens, it smoothly animates into full screen using CSS transitions.

Let me elaborate. Our content is text, not MP4 files. So we review it with humans and AI, just like how software companies review their software. We may make mistakes, but that's okay because we maintain the content. We continuously im

Everything I do is driven by a single goal: to make my startup successful so I can innovate in edtech. Nothing else. You may not believe me, and you may think I have ulterior motives, but I don't. My only goal is to build technology th

First, I need to make my startup successful so I can continue innovating over the next 15 years. Open-sourcing our work could be a distraction at this stage. Maintaining an open-source project requires significant time and effort. It would

These are 14 hours of video, so it's easy to find mistakes. We've probably made plenty of them. But this isn't AI slop. We created the technology so that the content can be updated and improved over time. If we make mistakes,

All we want to do is innovate. We simply can't open source this because we're rewriting and rebuilding it every day.

There are some incorrect premises here. "The videos are LLM slop." - No, they're not. Watch them. "It's dogshit that no one can understand." - That's not true. Try it.

I couldn't agree more. But if you look at it from this perspective, you may understand why we use static videos for this demo. Definition: the AI tutor is some AI that can generate these videos. If that generation happens in real time,

No, not yet. It's something we may do in the future.
