Claude in Chrome side panel becomes a Claude Cowork session

Claude in Chrome 侧边栏升级为 Claude Cowork 会话

Anthropic upgraded the Claude Chrome extension side panel into a Claude Cowork session, so browser tasks carry over to desktop, web, and mobile apps. Available now on Max and Team plans, rolling out to Pro in weeks. Claude can work across tabs—e.g., pulling invoice data from vendor portals into a spreadsheet. A new pre-action check blocks steps that deviate from your original request, though Anthropic warns prompt injection risk can't be fully eliminated.

Why it matters: Anthropic upgraded the Chrome side panel to a full Claude Cowork session, with cross-device continuity — a real workflow improvement, not a minor tweak. Score held at 78 because it's currently limited to Max and Team plans, with Pro rollout weeks away, capping immediate reach.
