AI that generates 3blue1brown-style explainer videos
I've been building prototypes of new AI learning tools for months, but I recently learned that 3blue1brown open sourced his incredible math animation library, Manim, and that LLMs could generate code for it without any fine-tuning. So I made a tool that automatically generates animated math/science explanations in the style of 3blue1brown using Manim from any text prompt. Try it yourself at https://TMA.live (no signup required) or see the demo video here: https://x.com/i/status/1874948287759081608 The UX is pretty simple right now, you just write a…
AI that generates 3blue1brown-style explainer videos launched on January 3, 2025 with 93 votes, #395 of 6,142 launches that month and more than 95% of that year's launches.
In plain words
This tool automatically generates animated math and science explainer videos from text prompts using the Manim animation library. It produces videos styled after 3blue1brown's educational content, allowing users to input a topic and watch the animation render in real-time before downloading. The tool requires no signup and is designed for students, educators, and anyone seeking visual explanations of complex concepts through animated diagrams and visualizations.

I ported Manim to TypeScript (run 3b1B math animations in the browser)Feb 2026 · github.com · ▲140Hi 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-PilotApr 2026 · x-pilot.ai · ▲328Hi 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 guides2024 · stepify.tech · ▲271Hey 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…
Manim (3Blue1Brown's animation engine) in the browser via WebGPUJul 2026 · studio.academa.ai · ▲49Grant 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:…

- TITetris in a PDF▲1,289
I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…

21st.dev▲1,211I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!
