Why This Matters

Claude's new full Cowork session feature in Chrome's side panel enhances cross-platform workflow continuity, allowing users to seamlessly carry browser-based tasks across Claude’s apps. This development improves productivity by maintaining conversation context and enabling more integrated browser interactions, which is crucial for both enterprise and individual users. It signifies a step toward more unified AI-assisted workflows within the tech industry, emphasizing portability and ease of use.

Skills and connectors already configured for an account also work from the browser without additional setup. Claude in Chrome can see the current page and act on it using a person’s existing browser logins. That includes clicking links, moving between pages, entering text, and filling out forms.

Anthropic’s example involves asking Claude to collect invoice details from several vendor portals, build a spreadsheet, then continuing the same session on desktop to add local files or compare the result with a previous budget.

Anthropic recently highlighted Claude Code’s in-app browser, which uses an isolated profile. By comparison, the Chrome extension works with websites where the user is already signed in.

Anthropic warns that browser agents remain vulnerable to prompt injection.

A separate check reviews consequential actions when automatic approval is enabled, while Claude still asks before actions such as purchases or sharing personal data.

The company says these safeguards reduce risk but cannot eliminate it.
