Description
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 scenes3. LLM generates Manim code for each scene4. FFmpeg concatenates everything into a final videoCurrently working on TTS integration for narration!Would love feedback on the approach and ideas for the TTS integration

Same idea, different domain
Nobody's really built a content generation tool for Government yet.
