- What they did
- Claude’s Cowork mode opens a built-in browser in a side panel when a task involves a website, so the agent can fetch information from a specified site, navigate pages, click, and fill forms while the user watches. The post says this works without installing the Chrome extension, uses a browser separate from the user’s own tabs and logins, and allows optional import of saved Chrome logins.
- How it went
- The example shown is a pricing comparison workflow that starts pulling prices from a chosen site. The post gives rollout details for paid desktop users, but no performance numbers or failure cases.
- Worth knowing
- It is separate from your normal browser by default, and importing saved Chrome logins is opt-in.
