What happened
Anthropic is rolling out its Claude Cowork AI platform to mobile (iOS and Android) and web starting Tuesday, initially for Max subscribers and then to other Claude users in the coming weeks. Cowork sessions now run in the cloud by default, allowing users to continue tasks across devices and run them in the background even when devices are offline. Anthropic is also extending doubled Cowork usage limits through August 5th.
Why it matters
Previously, Cowork was only available through the desktop app for macOS and Windows, so this expansion makes the tool accessible to more users and on more devices. Cloud-based sessions mean work can persist and be reviewed across phones, tablets, and computers without interruption—a practical benefit for teams managing multiple tasks.
What to watch
The full experience, including local file access, remains on the desktop app; mobile and web users can receive notifications when Cowork has something ready for review or approval. Users can still opt for local processing on desktop, choosing between cloud and local processing modes.

Claude Cowork, previously confined to macOS and Windows desktop applications, is now accessible across mobile and web platforms, addressing a key limitation for users who work across multiple devices. The shift to cloud-based session management by default is the critical change here: it enables work to persist and continue seamlessly whether a user is on a phone, tablet, or desktop, and allows scheduled tasks to run even when all devices are offline. This removes friction from the user experience and makes the tool more practical for distributed or asynchronous workflows.
The rollout strategy—starting with Max subscribers and expanding to other plan tiers in the coming weeks—suggests Anthropic is managing adoption gradually. The extended doubled usage limits through August 5th may indicate the company is testing capacity or encouraging trial use during the expansion period. Users should note that the full feature set, particularly local file access, remains on desktop, so power users will likely still rely on the desktop app for comprehensive work, while mobile and web serve as extensions for task management and notifications.
