What is it?

Pi Tab brings the Pi Agent into the web page you are viewing. Clicking a bookmark or a Chrome toolbar icon opens an agent panel that can read page content, click and fill elements, inspect the DOM and styles, and run JavaScript, without setting up a separate automation environment.

Sessions are saved locally in the browser and can be resumed later. In bookmark mode, unfinished tasks are restored after a refresh; in extension mode, background tasks keep running across page reloads. Users can configure multiple model providers and switch models from the input area, and the extension supports OAuth sign-in for some providers.

The Chrome extension also includes an in-browser Linux environment per session with bash, read, grep and edit tools, and a built-in curl that sends HTTP(S) requests from the extension background. Model requests go to the service you configure, and page content sent with a task goes to that service.

Key features

  • 01One-click launch from a bookmark, with no plugin or server to deploy.
  • 02Reads and edits the current page through its content and DOM.
  • 03Local session history that can be resumed, with unfinished tasks restored after refresh.
  • 04Multiple model providers, with per-model thinking level settings.
  • 05Chrome extension mode supports cross-tab agent collaboration.

Use cases

  • Summarizing a long web page or extracting tables into CSV or JSON.
  • Inspecting why a page layout breaks, such as an unexpected horizontal scrollbar.
  • Automating form filling or clicks on a page you are already viewing.
  • Debugging page JavaScript and styles directly in the browser.

Quick start

  1. 1

    Open the install page and try it (bookmarklet, no extension needed)

  2. 2

    Drag the Pi Tab button to your browser bookmarks bar

  3. 3

    Open a target web page, click the bookmark, and enter a task

Things to know

  • Model inference requires an external model service with your own configured API key or account login.
  • Page content and attachments are sent to the configured model provider, and bookmarks may contain API keys.
  • Does not run on browser-internal pages or pages that block script injection; only regular HTTP/HTTPS pages.
  • Sessions are stored locally with no cloud sync.
