[Claude Turns Chrome Sidebar into Cowork: Start in Browser, Continue on Mobile] According to monitoring by Beating, Anthropic has upgraded the Claude in Chrome sidebar into a full-fledged Claude Cowork session. Sessions are now directly saved to user accounts, allowing users to start working in the browser and then continue on desktop, web, or mobile. Claude in Chrome can also directly utilize Cowork's Skills, plugins, and connectors. It can read webpages, click buttons, input content, and fill out forms. For tasks involving local files or requiring Claude to actively operate the computer, Claude Desktop still needs to remain connected. In July, Anthropic had already expanded Cowork to web and mobile, and now the Chrome sidebar has been integrated into the same cross-device session system. Cowork has evolved from an independent desktop agent into an agent capable of seamless work across browsers, computers, and mobile devices. The new sidebar version is currently available to Max and Team users, with Pro users set to receive access in the coming weeks. Enterprise users will need administrators to enable it. [Original Link]
