PolyCast turns a JSON script into a low-poly 3D podcast video. Two characters banter in a studio, voices come from Cartesia or your computer's free built-in voice, lip-sync runs off the real audio, and camera cuts and captions are cued to the exact word. It renders frame by frame with Three.js in headless Chrome, and it also works as a Claude Code skill: describe a video, get the MP4. Free and MIT licensed.

Could you build this?
Yes The pipeline is standard: a script feeds TTS APIs (Cartesia or the browser's built-in voices), audio drives lip-sync and caption timing, and Three.js renders the scene frame by frame. Each piece is well documented, so a solo builder can assemble it with an AI assistant.
