Claude introduces built-in browser for enhanced web task automation

Anthropic has integrated a built-in browser into its Claude Cowork desktop application, allowing the AI to independently perform web-based tasks. When a task requires accessing a website, a browser automatically opens in the sidebar, enabling Claude to navigate, read content, click buttons, and input text. This feature is now rolling out to Pro, Max, and Team users of the Claude desktop application, with Enterprise administrators able to enable it for their organizations starting today. The built-in browser operates independently from the user’s default browser, meaning it cannot access open tabs, bookmarks, or saved passwords. Users can manually import login credentials for specific websites, with support for Chrome, Edge, and Firefox on macOS, and Firefox on Windows and Linux. However, sensitive sites like banks, email services, and single sign-on platforms are not imported by default unless users choose to include them. This new functionality allows users to delegate web-based tasks to Claude, such as gathering data for reports or organizing invoices from supplier portals, while continuing with other work. In contrast, the existing Claude in Chrome extension is better suited for interacting with websites already open in the user’s browser, such as updating CRM systems, managing email, or editing online documents. Users can switch between the built-in browser and Claude in Chrome via the settings menu. Anthropic has implemented security measures to mitigate risks such as prompt injection, where hidden instructions on a webpage might mislead Claude from its intended task. These measures include verifying that Claude’s actions align with the user’s original request. However, the company acknowledges that while these safeguards reduce risk, they cannot eliminate it entirely, and recommends users only allow Claude to access trusted websites. The built-in browser will be available on macOS, Windows, and Linux platforms for Pro, Max, and Team users in the coming week, with Windows and Linux versions still in testing. Once enabled, the browser will automatically open when a task requiring web access is assigned. Users who only access Claude through the web or mobile app can still use Claude in Chrome if the desktop application is running and connected to the internet. Enterprise users can manage the built-in browser through the organization settings menu.
