What is explainroo?
explainroo is a free, open source tool that turns your AI agent into an explainer video creator. You tell the agent what topic the video should cover. The agent writes the script and draws the visuals, and explainroo assembles them into a video with a voiceover, all on your own computer.
To use it, you copy a short prompt into your coding agent, such as Claude Code, Codex, or Pi. The prompt tells the agent to clone the explainroo repository, read its instructions, and follow the steps. You just replace the placeholder with your topic. The tool works best with Claude Code and Opus 5.5, according to the website.
This suits anyone who already works with coding agents and wants quick, narrated explainer videos without cloud services or API keys. The site notes it is free, open source, and runs locally. You can see example videos and read guides and docs on the website.

What to check before you rely on explainroo
- Confirm your coding agent can clone a GitHub repository and run local scripts, since explainroo requires that workflow and the website does not list other installation methods.
- Check that your computer has enough storage and processing power for video generation, as explainroo runs entirely locally and the site does not state minimum hardware requirements.
- Verify the output video format and resolution before relying on it for distribution, because the website does not specify what file types or quality settings explainroo produces.
