It treats your already logged-in Chrome session as a programmable workspace, so an agent can work on the page you are viewing instead of requiring a separate hosted browser. Select page content, describe the result, and receive session artifacts including sheets, documents, or site HTML. It is an unpacked extension, not a Chrome Web Store product.

The agent runs in an offscreen Session Workspace rather than the side panel or service worker. This keeps durable session state and model work alive outside Chrome's killable service worker, while browser privileges are routed through the service worker.
