explainroo
AI agents create explainer videos with voice and drawings on your computer
Visit explainroo.com ↗What is explainroo?
explainroo is a free, open source tool that lets AI coding agents generate explainer videos. You provide a topic to your agent, which writes a script and draws scenes using JavaScript. explainroo handles voice generation with Kokoro (28 voices, no API key needed), timing via Whisper, frame rendering through Chrome, and background music—all running locally. The tool outputs MP4 files and works best with Claude Code and Opus 5.5, though it supports other coding agents like Codex and Pi. Designed for developers and anyone wanting to automate video creation through AI agents.
