Cowork in the Claude desktop app now has an integrated browser, which automatically opens a browser in the sidebar when tasks involve websites. Claude can browse, read content, click buttons, and type text within it. This means users can hand over web operations to it and continue their work without installing extensions or additional settings.

Independent browser separated from "your browser"

The integrated browser is completely isolated from the user's daily browser, and Claude cannot see tabs, bookmarks, or saved passwords. If you want it to maintain login states for certain websites, you can import them one by one — macOS supports importing from Chrome, Edge, and Firefox, while Windows and Linux only support Firefox; banking, email, and single sign-on sites are not imported by default unless the user actively adds them.

This feature is being rolled out to desktop Pro, Max, and Team users this week, and Enterprise administrators can now enable it organization-wide. Anthropic reminds that AI operating browsers also faces the risk of prompt injection, and hidden instructions on web pages may mislead Claude from its original task. Therefore, the same security checks as in Claude in Chrome are used, but the risk cannot be completely eliminated. It is recommended to prioritize visiting trusted sites.

Both browsers have their own use cases: the integrated browser is suitable for handing over entire tasks to Claude (such as collecting report materials, organizing supplier invoices); Claude in Chrome is suitable for operating already opened and logged-in pages (such as updating CRM, handling inbox). Users can switch at any time in the settings, and those who have not used the extension will default to the integrated browser.
