Claude Cowork breaks out of the desktop

AI agents made a name for themselves by writing code, but it turns out the real world just wants them to clear out office busywork.

Anthropic is rolling out Claude Cowork to web and mobile browsers as well as iOS and Android apps. The beta is hitting Max plan subscribers first, with access expanding to other tiers over the coming weeks.

Work keeps moving after you close the lid

Cowork originally launched in January as a desktop-only tool. If you stepped away from your desk or slammed your laptop shut, whatever Claude was doing simply paused.

That limitation is gone. Cowork sessions now run in the cloud by default. You can kick off a complex task on your computer, close the machine, head to a meeting, and check progress from your phone.

Anthropic says scheduled tasks can even run when every single one of your personal devices is offline. You can tell Claude to wake up at 6 a.m., dig through scattered email threads and meeting transcripts, draft a client briefing, and stage a follow-up email that sits unsent until you give the green light over morning coffee.

Crucial checkpoints still route back to you. When Claude hits a decision branch requiring human judgment, it pings your phone. You redirect or approve it on the go, and it carries on. Local file and browser access still require the desktop app for heavy lifting, but the web app opens the door for corporate users locked out by IT installation rules.

To grease the wheels, Anthropic is extending doubled usage limits for Cowork through August 5.

Nobody is using it for software

Alongside the launch, Anthropic shared fascinating telemetry from 1.2 million Cowork sessions across 600,000 organizations in late May.

Over 90% of Cowork sessions had nothing to do with software development. Coding accounted for a mere 8.7% of activity.

Instead, business process operations took the lion's share at 33.4%. People used it for spreadsheet reconciliations, onboarding checklists, and turning piles of vendor contracts into renewal schedules. Content creation and copywriting took another 16.4%, spanning client slide decks, memos, and proposals.

It is the unglamorous "work around the work" that clogs up calendars across finance, HR, and marketing.

Why it matters

We think this is one of the smartest product shifts Anthropic has made all year.

For non-technical knowledge workers, a desktop-bound AI agent felt like an awkward half-measure. Real work is fragmented across meeting rooms, commutes, and scattered devices. Letting an agent crunch data asynchronously in the cloud while surfacing only the final approval to a smartphone screen turns Cowork from a novelty into an actual administrative colleague.

Across the industry, this signals that the frontier AI battle is moving away from terminal windows and straight into executive suites. OpenAI has steadily nudged its developer tooling toward everyday white-collar reporting, and Anthropic recently planted Claude Tag inside Slack. The race is no longer about who generates the cleanest Python script; it is about who captures the background execution of daily corporate operations.

The real test will be trust and verification. Reviewing a 15-page financial briefing on a laptop screen is hard enough; skimming an AI-generated draft on an iPhone between subway stops invites rubber-stamping. As background execution becomes effortless, human oversight risks becoming the dangerous bottleneck.
