Show HN: Turn any topic into a 3Blue1Brown-style video

https://github.com/mateolafalce/topic2manim
4•lafalce•19h ago
Hey HN! I built Topic2Manim to automate the creation of educational videos like those from 3Blue1Brown.

The workflow is simple:

1. Give it any topic (e.g., "how ChatGPT works")

2. An LLM generates an educational script divided into scenes

3. LLM generates Manim code for each scene

4. FFmpeg concatenates everything into a final video

Currently working on TTS integration for narration!

Would love feedback on the approach and ideas for the TTS integration
