Claude Cowork Adds Built-in Browser for Autonomous Web Navigation

Anthropic has introduced a built-in browser within the Claude Cowork desktop app, enabling Claude to autonomously navigate websites, read pages, click elements, and fill forms. This allows users to delegate web-based tasks, such as pulling data from dashboards or completing forms, directly within the side panel. While this removes the need for an extension for new web tasks, Claude in Chrome remains the preferred tool for tasks involving already-open tabs or existing sessions, such as editing documents or updating CRMs.

The new browser operates independently of the user's personal browser, ensuring that tabs, bookmarks, and passwords remain private unless logins are explicitly imported from Chrome, Edge, or Firefox. Banking, email, and single sign-on sites are excluded by default.

The feature is rolling out to Pro, Max, and Team plans on the Claude desktop app for macOS, Windows, and Linux (in beta). Enterprise admins can enable it for their organizations. While the built-in browser carries standard prompt injection risks, it employs the same safety checks as Claude in Chrome. It is enabled by default once available, but users can switch between the built-in browser and Claude in Chrome in Settings.
