# AIRI Plugin - Web Extension > Read what you are reading! This is a plugin for the AIRI to understand what you are reading, looking at, or listening to on the web. ## What it does now - Captures page + video context from YouTube and Bilibili. - Extracts subtitles from text tracks or DOM overlays. - Sends context updates and optional `spark:notify` events to the character. - Exposes a popup to configure WebSocket, toggles, and quick status. ## Quick start 1. `pnpm -F @proj-airi/airi-plugin-web-extension dev` 2. Load the unpacked extension from `.wxt/dev` in your browser. 3. Open the popup to set the WebSocket URL (default: `ws://localhost:6121/ws`). 4. Watch a YouTube/Bilibili video and confirm the popup shows the detected title/subtitle.
