Anthropic announced Tuesday that Claude Cowork, its agentic tool for delegating multistep work tasks, is expanding beyond desktop to mobile and web platforms, according to the company's blog post. Beta access is rolling out first to Max plan subscribers over the coming days, with availability expanding to additional plans in the following weeks.
Cowork allows users to hand Claude a task spanning files, calendar, email, messaging apps, and other connected tools until the job is complete. Per Anthropic, more than 90 percent of Cowork usage has come from everyday knowledge work rather than software development, with business operations and content creation representing roughly half of all activity — tasks like reconciling quarterly spending, converting contracts into renewal trackers, or building presentations from call transcripts.
The company said the expansion allows sessions to span devices, so users can start a task on a desktop and check progress or retrieve finished work on a phone. Tasks can also continue running in the background without a device connected; scheduled jobs, for instance, can run overnight and be ready for review by morning. Anthropic emphasized that Claude will still pause and ask for input when a decision requires human judgment, and that no output is finalized without user review.

On web and desktop, chat and Cowork will now share a single unified interface, with projects and artifacts accessible across both experiences from launch. The desktop app remains the most complete version of Cowork, retaining access to local files and browser integration, while the mobile and web versions extend access to users who previously could not install the desktop application.
To coincide with the launch, Anthropic said it is doubling Cowork usage limits through Aug. 5.
