Claude Chrome Extension with Cowork

Claude in Chrome is a browser extension that lets Claude see the page you are on and act in it: clicking links, typing, navigating between pages and filling out forms using your existing logins. With this update, the side panel is a Claude Cowork session rather than a separate browser-only chat. Conversations are saved to your history, skills and connectors work in the browser, and a task started in a tab can be continued on the Claude desktop, web and mobile apps.

It is aimed at multi-step work in tools that do not have direct connectors, such as internal dashboards, legacy systems and vendor portals. Anthropic's example is collecting invoice amounts and dates from several vendor portals into a spreadsheet, then continuing in the desktop app. A new "automatically approve" mode lets Claude proceed without per-step prompts, while a separate check reviews consequential actions (submitting forms, sending messages, downloading files) against the original request. Claude still asks before purchases or sharing personal data.

The extension is installed from the Chrome Web Store. The new side panel is available on Max and Team plans and was rolling out to Pro users over the following weeks. On Enterprise plans it is off by default and admins can enable it and limit it to approved domains. Limits: Anthropic notes that prompt injection remains a risk that its safeguards reduce but cannot eliminate; working with local files or other applications still requires the desktop app; it does not run on other Chromium browsers or on mobile yet.
