What it is
AntiRot is a shipped browser extension backed by a FastAPI service. The extension watches YouTube navigation, sends the current video URL to the server, and shows a blocking overlay when the video is classified as low-value.
How it works
The backend pulls the transcript through Supadata, routes it through OpenRouter, and forces a binary answer: allow useful educational or skill-building content, block the rest. Custom instructions in the extension can override the default rules for a session.
What shipped
- Chrome Manifest V3 extension with popup controls and DOM blocking.
- FastAPI classification endpoint with health checks and Docker deployment support.
- Fail-open behavior so API failures never trap the user away from a video.
- Custom per-session rules like allowing specific categories or blocking others.
