   I ported Manim to TypeScript (run 3b1B math animations in the browser)▲140

   Hi HN, I'm Narek. I built Manim-Web, a TypeScript/JavaScript port of 3Blue1Brown’s popular Manim math animation engine. The Problem: Like many here, I love Manim's visual style. But setting it up locally is notoriously painful - it requires Python, FFmpeg, Cairo, and a full LaTeX distribution. It creates a massive barrier to entry, especially for students or people who just want to quickly visualize a concept. The Solution: I wanted to make it zero-setup, so I ported the engine to TypeScript. Manim-Web runs entirely client-side in the browser. No Python, no servers, no install. It runs…

   X-Pilot▲328

   Hi HN, I'm Heshan, founder of X-Pilot. We're building an AI Video Generator for online courses and educational content. Unlike most text-to-video generator that render videos directly from models (which often produce random stock footage unrelated to the actual content), we take a code-first approach: generate editable code layers, let users verify/refine them, then render to video. The Problem We're Solving Most AI video generators treat "education" and "marketing" the same—they optimize for "looks good" rather than "logically accurate." When you feed a technical tutorial or course…

   I made a website that converts YT videos into step-by-step guides▲271

   Hey HN, I've been working on this side project for the past month. It generates a step-by-step tutorial guide for YouTube videos that you can follow along without watching long videos. Best suited for tutorial videos but can work for other videos aswell. No BS. Just straight to the point. The guides are generated from pure transcript so you don't have to worry about it being AI. It's my first project as a total beginner. Something I had to do inorder to get out of tutorial hell. Please let me know if you have any suggestions or if you face any problems or bugs. I would try to fix them to the…

   I'm a teacher and built an AI presentation tool▲260

   Hi, I'm a high school teacher from Australia and I've built what I'd like to think is a pretty nifty ChatGPT powered presentation tool for teachers. I'd love it if you could have a look at it and give me some of your feedback. I don't think there's much overlap with the HN crowd and school teachers, but I've been coming here for many years and thought I'd post here and see what you all think. Check it out if you have a minute and I'd be super happy to hear your feedback too. https://www.slidehero.ai/ You can jump in and have a play with the tool all you like ;) Cheers, Eli

    Manim (3Blue1Brown's animation engine) in the browser via WebGPU▲49

    Grant Sanderson (3Blue1Brown) created Manim, the Python library he uses to make the math animations in his videos. We reimplemented Manim with the same Python API, but the implementation underneath is Rust, connected to Python through PyO3. The Rust code uses wgpu, so rendering happens on the GPU. To run it in the browser, we compiled the Rust parts to WebAssembly so the PyO3 extension loads in Pyodide. In the browser, wgpu targets the WebGPU API, so animations render in real time on your GPU through the browser. The editor is Monaco (the editor that powers VS Code) with a live preview:…

    A YouTube videos course generator▲56

    An exciting aspect of what I'm working on is that users can create their own playlists. For example, you can provide an outline of what you're learning, such as notes from your professor or any other structure, and the pipeline will create a course tailored to that. Since the content is highly customized, it will be relevant and high-quality, matching current lessons or lectures in school or university. Initially, the pipeline also generated some teaching content using AI, but due to the risk of AI hallucinations, I'm planning to pivot away from that. The new focus will be on curating…

    Torial▲17

    I'm a huge fan of 3B1B and how he creates appealing and easy-to-understand videos. But he doesn't have a video for every single topic. Whenever I needed help in math or physics, I would try to watch his videos but the issue is that are just not specific enough to my content or curriculum. This issue applies to every single video explanation out there, they just aren't personalized. Most educational videos explain general topics, but they don’t align perfectly with the specific question I have or the way I need it explained. That’s the gap I wanted to fill. So I built a tool that generates…

    Beautiful interactive explainers generated with Claude Code▲43

    Hello HN, Recently an amazingly beautiful explainer was shared on HN: https://explainers.blog/posts/why-is-the-sky-blue/ I loved it so much that I wished more topics were explained that way. So, I decided to stress-test today's frontier models (Opus 4.6 in Claude Code) to generate similar explainer on any given topic WITH (almost) one shot and minimal nudging. I'm launching with four topics: Fourier transformation, scaling laws in bio, cellular automata and LLMs. I would let you be the judge, but I'm quite liking them. Some things I learned: - Prompting CC to test…
