Been lurking here a while. Finally shipping something.
Built Madio you describe a math concept in plain english, it generates a 3Blue1Brown-style animation in ~20 seconds.
Two things I'm most proud of:
1. Self-correcting render loop — if the AI writes bad Manim code, it feeds the error back and auto-fixes before you ever see a failure. 3 retry attempts.
2. AI audio narration — after the animation renders, a second AI pass writes a voiceover script timed to the video length, synthesizes it with a natural voice (7 options), and merges it into the final MP4. Your animation ships with a built-in teacher explaining the concept.
Stack: React + FastAPI + Gemini 2.5 Pro + Manim + Celery + edge-tts + ffmpeg
Free tier available. Brutal feedback welcome — especially from anyone who's actually tried Manim before.
