Kai WebBridge

Let a local AI agent drive your real Chrome through the Kai WebBridge daemon. Open source, no telemetry.

Kai WebBridge connects a local agent to the browser you already use. It is not a headless browser and not a cloud service: a small daemon runs on `127.0.0.1`, and this extension executes commands in your real tabs, with your real logins. What it can do: - Open pages and collect each task's tabs into a visible tab group. - Attach to pages the user already has open, without moving or closing them. - Read the page as an accessibility tree with stable `@e` element references. - Click, type, scroll, upload files, and handle JavaScript dialogs. - Take screenshots and save pages as PDFs to local files. - Run JavaScript and raw Chrome DevTools Protocol commands when the local agent asks. - Capture network requests for a tab while capture is enabled. - Numbered interactive map and full-page screenshot whenever a page is opened, attached, or resumed. - Batch actions such as `!2:t:"text",1:c!` fill and click several elements in one call. - Resume a task after a daemon restart; a status side panel shows the connected browser and daemon state. Privacy: - No accounts, analytics, telemetry, ads, or cloud component. - Page data is processed locally by the daemon on your machine. - The daemon listens on `127.0.0.1` only. - The source is MIT-licensed and auditable. Requirements: - A Chromium-based browser (Chrome, Edge, Brave, Opera, or Vivaldi) 120+. - Node.js 20+ and the Kai WebBridge daemon: `npx -y kai-webbridge setup`. The command installs the daemon, copies this extension to a stable folder, and starts the local service. Load the printed folder with "Load unpacked". The extension is a companion for the open-source daemon. It does nothing without the daemon running.
