Claude Cowork now runs on web and mobile. The agent moved off your desk, and off your machine.

Anthropic's Cowork agent, once desktop-only, is in beta on web and mobile. Cloud sessions run on Anthropic's servers and scheduled work continues with no device online, which changes where the work happens and what it can reach unattended.

What changed

Anthropic put Claude Cowork into beta on web and mobile for Pro, Max and Team plans, and for Enterprise plans where an admin has enabled it. Cloud sessions run on Anthropic's servers rather than your computer, sessions and files save to your Claude account, and scheduled tasks run with no device online. Local file access, browser use and computer use remain desktop-only.

Why it matters

An agent you could once only run while watching it on your own machine can now work on a server while your devices are off. That removes friction, but it also moves your files and task context into cloud sessions and lets scheduled work act while nobody is present, so where data lives and who reviews an unattended run matter more than before.

Bit’s takeaway

What not to assumeDo not assume a cloud Cowork session has the same reach, storage or oversight as a desktop session you watch: local file, browser and computer use stay desktop-only, and cloud sessions save to your Claude account.

The human take

A person still decides what an unattended agent may touch and reviews what a scheduled run produced before it counts as done.
