Anthropic expands Claude Cowork to web and mobile as 90% of usage bypasses coding

Anthropic expanded Claude Cowork to web browsers and mobile devices on Tuesday, letting users carry conversations and file operations across laptops and phones. The company also revealed something unexpected: more than 90% of Cowork usage has nothing to do with software development.

Claude Cowork is Anthropic’s task agent — users hand off specific work to an AI that crosses files, calendars, email, messaging apps, the web, and other connected tools until the job is done. Think research compilation, document drafting, and client preparation. Knowledge-work tasks that traditionally eat hours get handed to a background process instead.

The 90% non-coding figure is worth pausing on. It cuts against the widespread assumption that AI agents are primarily developer tools. Business operations and content creation together account for roughly half of all Cowork usage. People are using it to reconcile expenses, draft variance memos, track contract renewals, and organize client materials — the sort of back-office busywork that rarely makes headlines but consumes enormous amounts of white-collar time.

With this update, tasks roam across devices. Start something on desktop, check progress on your phone, collect the results wherever you land. Anthropic also upgraded the background execution engine: scheduled tasks can now run even when no device is online. The company shared one example — a Monday morning client prep session set to kick off at 6 AM. Claude reads email threads, call records, and recent news, generates a briefing document, and drafts a follow-up note without sending it. The user reviews the output when they wake up.

On the safety side, Claude still asks for confirmation on key decisions, pinging the user’s phone when needed. Nothing gets dispatched until the user signs off.

The web and mobile rollout is still in beta, opening first to Max subscribers. Anthropic says it will invite more users in batches over the coming weeks.
