Hi Product Hunt — I’m the builder behind Matemium. I started this project because writing a substantial technical animation often meant spending more time coordinating positions, camera moves, object lifetimes, and transitions than thinking about the explanation itself. Matemium treats that as a compiler problem. A project describes structured content through Python `scenes.py` using `CanvasBuilder` and `CanvasScene`. The engine handles layout, persistent visual identities, validated actions, and compilation to Manim. Its main canvas is an infinite vertical reasoning tape, but projects can also move into a free 3D world and return to isolated camera-facing tapes for equations, plots, or diagrams. Everything renders locally. The desktop app uses a TypeScript interface, a Tauri/Rust shell, and a Python sidecar that runs Matemium and Manim on the user’s computer. AI can help work on the same inspectable project files, using the user’s own provider access; Matemium does not sell AI credits or send rendering to a cloud farm. I’m launching before the product has reached imaginary “perfect” status. That is intentional. Installation still needs more clean-machine testing, FFmpeg and LaTeX remain host prerequisites, some builds may show signing or notarization warnings, and the most ambitious autonomous production workflow still needs harder verification and evaluation. The example library also contains projects at different review stages rather than a wall of finished showcase pieces. The foundation is working, and keeping it private would now hide more problems than it solves. I want early users to try subjects and workflows I did not anticipate, tell me where the API is awkward, share failed renders, and question the product architecture. Those reports can shape Matemium while its abstractions are still changeable. Matemium is free and source-available—not open-source. You can inspect the code, use it for the purposes described in the license, make permitted private modifications, and contribute improvements to the official project. Please read the license for the exact boundaries. If you make visual explanations, teach, work with Manim, or build local creative tools, I would be grateful for a candid first run. What should become simpler first?
