Anthropic has integrated a built-in browser into its Claude desktop application, a move that removes the reliance on external extensions for many web-based tasks. The update, announced on Wednesday, brings a built-in Chromium-based browser to Claude on the desktop across macOS, Windows, and Linux platforms.
The transition to a native tool aligns the desktop software with current industry trends, mirroring similar features found in competing generative AI products. This functionality is available to Pro, Max, and Team plan subscribers.
By housing the browser within the application, the system can now execute web requests without requiring a separate installation.

Previously, users relied on the Claude in Chrome extension to provide the model with internet access. While that method functioned, it often felt like a workaround. Anthropic indicated that the extension remains relevant for specific tasks, such as analyzing a webpage currently active in a user’s primary browser or managing documents and email accounts where existing login sessions are required.
The new browser is designed as a standalone environment, meaning it does not automatically share the user’s personal browsing history or saved credentials. To facilitate functionality, the software allows for the importation of login data from Chrome, Edge, and Firefox, though this process varies by operating system. Access to banking portals, email services, and single sign-on providers is restricted to maintain security boundaries.
These limitations stem from the way different operating systems handle local data storage. On Windows, Chrome and Edge employ security measures to prevent third-party access to local cookies. Firefox, by contrast, stores information in a SQLite database that is more accessible to other applications. These technical disparities dictate the specific ways a user can move their authentication data into the new environment.

Despite the implementation of security safeguards, Anthropic acknowledges that the potential for prompt injections remains when an agent is granted access to the internet. They emphasize that the risk is not zero, though they expect the blast radius of any potential issue to be contained due to the lack of access to highly sensitive accounts.
The older extension will remain the default for web tasks unless a user manually adjusts their settings within the Claude Desktop menu. This ensures that users who prefer the existing workflow for managing active sessions can continue to do so without interruption. The developers maintain that this tool is intended to be the model’s browser rather than a replacement for the user’s own primary web navigator.
