Anthropic’s AI work agent, Claude Cowork, has expanded to the web and mobile. TechCrunch reported on July 7 that Claude Cowork, introduced as a desktop app in January, will be available from July 8 on web and mobile for Max subscribers.

Users can check work started at a desk on a smartphone and pick up results later even after closing a laptop. With the expansion to a multi-platform app, tasks can continue running in the background even if a specific device is not online.

Claude Cowork started as a “Claude Code”-style agent for general knowledge work, but the expansion has moved it closer to an AI companion that supports general office work rather than a coding tool. It lets users continue work across multiple devices and requests input only when user judgment is needed.

The desktop app remains focused on advanced work that accesses local files and browsers. With the addition of web and mobile versions, users who have not installed the app can also use Claude Cowork.

Anthropic also released early usage data. An analysis of a sample of more than 1.2 million anonymised and aggregated sessions from more than 600,000 organisations over the last two weeks of May found the largest area of use was business process operations, accounting for 33.4 percent.

Content creation and copywriting was next at 16.4 percent. It included communication tasks such as drafting, slide materials, social posts and proposals. Software development, by contrast, accounted for 8.7 percent of total use.
