Claude Cowork leaves the desktop and puts agent work in your pocket

Anthropic is bringing Claude Cowork to web, iOS and Android, starting with Max subscribers before expanding to other plans. That turns the agent feature into a cloud-running service, not just a tool pinned to one computer.

Cowork moves from the desktop app to web and mobile

The Verge reports that Claude Cowork will be available on web and mobile for the first time starting Tuesday. The rollout begins with Max subscribers and is expected to reach users on other plans in the coming weeks.

Cowork was previously available through the Claude desktop app for macOS and Windows. Users on iOS and Android can now use it too, while Anthropic says the full experience remains on desktop, especially for features such as local file access.

The important change is cloud processing. Cowork sessions now run in the cloud by default, so a user can start a task on a computer, check status on a phone and return to the result later. The desktop app still offers a switch between cloud and local processing.

The agent becomes a running service, not a window on a laptop

For users, this sounds like convenience. Product-wise, it is a deeper shift. If the agent keeps working when the laptop is closed, expectations change: the task should continue, send notifications and remain reachable across devices.

That pushes Claude Cowork closer to workplace infrastructure. The point is not merely opening an agent on a phone. Anthropic is training users to hand off longer tasks and supervise them asynchronously, the way they already check a build, export or approval workflow.

For companies, permissions become the key question. A desktop agent with local files is one kind of risk. A cloud agent that carries work state across devices needs clear controls for data, logs, notifications and the boundary between personal and corporate context.

Mobile access does not mean full agent work everywhere

Anthropic is keeping a brake on the story: the full Cowork experience remains on desktop. That matters because local file access, deeper integrations and larger artifacts are hard to replace on a phone.

The rollout is also gradual and aimed first at paid users, not a universal switch for everyone. Without precise limits for each plan, part of the value remains unclear: an agent that continues in the cloud is useful only if limits and governance allow normal work.

Adoption will show whether people assign work away from the desktop

The next signal is how many users actually start Cowork tasks from web or mobile and let them run without an open laptop. The second signal is enterprise administration: admin controls, audit logs, data retention and clean separation of personal and work tasks.

If Anthropic gets those layers right, Cowork can become a normal queue for long-running work. If not, mobile access is mostly a remote control for an agent people still trust most at their desk.

Lilith's verdict

Mobile Cowork is a small phone in the pocket and a large bet on user discipline. An agent that works without an open laptop needs less shiny UI and better locks on the door.
