Claude Cowork gets its own built-in browser

Claude Cowork on the desktop app gained a built-in browser. Claude opens its own browser in the side panel to navigate sites, read pages, and fill forms. It is rolling out to Pro, Max, and Team plans, separate from the user’s own browser.

Why it mattered Cowork no longer needs the user’s browser to do web work. A dedicated agent browser cuts setup and permission risk.

Claude Cowork gains a built-in browser that opens in the desktop app’s side panel. The browser is separate and never sees the user’s tabs, bookmarks, or passwords. It rolls out to Pro, Max, and Team, with Enterprise admins able to enable it now. It uses the same prompt-injection safeguards as Claude in Chrome.
