Explainroo is an open-source framework that lets AI coding agents generate explainer videos by writing a script and scene code, then rendering with local TTS, word timing, and animated drawings. It combines Kokoro, Whisper, Rough.js, and ffmpeg into a fully local pipeline, supporting multiple languages, looks, and sizes. The project is notable for agent-friendly verification tools and product demo automation.
