Claude Cowork AI Agent Expands to Mobile and Web
Anthropic is taking Claude Cowork off the desktop leash. The AI agent, which launched as a desktop-only feature, is now rolling out to mobile and web, with beta access arriving gradually over the coming weeks starting with Max subscribers. That means a task started on a laptop can be checked from a phone and finished in a browser somewhere else entirely, with Claude grinding away in the background even after the laptop lid closes or the phone screen goes dark.
The expansion also carries over Cowork's approval system. When Claude reaches a decision only a human can make, it pings the user's phone directly, and Anthropic says nothing gets sent or finalized without that sign-off. That matters more than it might sound, given what people are actually using Cowork for.
Anthropic says over 90 percent of Cowork activity has nothing to do with software or code. Business operations and content creation, think expense reconciliation or drafting client decks from transcripts, account for roughly half of all usage between them, according to the company.
Nothing gets sent without the user reviewing and approving it first, Anthropic says.
Why this matters
For anyone building workflows around Claude, this splits the product into two tiers whether Anthropic frames it that way or not. Mobile and web get you visibility and task-checking, but the actual heavy lifting, anything touching local files, connectors, or Computer Use, still lives on desktop. That's a reasonable engineering tradeoff, but it means "Claude Cowork on mobile" is really "Claude Cowork status updates on mobile" for now.
Founders evaluating Cowork for team use should plan around that gap rather than assume parity across platforms. The staggered beta rollout, starting with Max subscribers, also tells us Anthropic is still testing how this holds up at scale before opening it wider, which is worth watching if you're deciding whether to build internal tooling on top of it today or wait. The bigger signal here isn't the mobile app itself, it's Anthropic continuing to push Claude toward being an agent you check in on rather than a chat window you sit in front of.
Where that leaves desktop-dependent features over the next few releases is the thing to track.

Common Questions Answered
What are the key differences between Claude Cowork on desktop versus mobile and web?
Desktop remains the primary platform for heavy lifting tasks including local file access, connectors, and Computer Use functionality. Mobile and web versions currently provide visibility and task-checking capabilities, allowing users to monitor and review Claude's work in progress, but the actual execution of complex operations still occurs on the desktop platform.
How does Claude Cowork's rollout to mobile and web work for Max subscribers?
Claude Cowork is rolling out to mobile and web gradually over the coming weeks, with Max subscribers receiving beta access first. This expansion enables users to start tasks on a laptop, check progress from a phone, and finish work in a browser, while Claude continues operating in the background even when devices are locked or closed.
What safety measures does Anthropic implement for Claude Cowork actions on mobile and web?
Anthropic ensures that nothing gets sent or executed without the user reviewing and approving it first. This approval requirement applies across all platforms, maintaining user control over Claude's autonomous actions regardless of whether the agent is running on desktop, mobile, or web.
Why is cross-device task continuity important for Claude Cowork users?
Cross-device continuity allows workflows to persist seamlessly across multiple devices, enabling users to start work on one device and continue on another without interruption. This flexibility means Claude can continue processing tasks in the background even after users close their laptops or turn off their phones, improving productivity for complex, multi-step workflows.
