Anthropic announced that Claude Cowork, its autonomous task-completion tool, is now available in beta on iPhone and the web, removing the platform constraint that had confined the feature to Mac and Windows desktops since launch. Max subscribers get early access over the next several weeks, followed by other paid plans.
Cowork lets Claude work continuously in the cloud even when your phone is locked or your laptop closed. You hand it a task, it accesses your files, email, calendar, and connected tools, and it works until done, alerting you only when it needs permission to proceed. That capability shifting from desktop-only to mobile and web changes when and where knowledge workers can delegate work to an AI agent.
With Claude Cowork for iPhone, you start a task at your desk, monitor progress from your phone during a meeting, and pick up the output anywhere. Claude keeps working in the background whether or not you are looking at it. On web and desktop, Chat and Cowork are now consolidated into a single sidebar, one search box, and one Projects and Artifacts view, rather than living in separate tabs as they did before.
Anthropic’s position is clear that the desktop remains the “best place” for the full Cowork experience. Mobile and web versions do not have access to local files or browser control, the two capabilities that make desktop Cowork powerful for automation. If your workflow requires Claude to read files from your Downloads folder or navigate a web app by clicking and typing, you still need the desktop app. For tasks that lean on cloud-connected tools (email, calendar, APIs, web search), mobile and web are now viable.
To mark this announcement, Anthropic is also extending doubled Cowork usage limits through August 5, 2026. The timing aligns with Anthropic’s broader capability push through 2026. Claude Fable 5 launched on June 9, 2026 as the company’s most capable public model, followed by Claude Sonnet 5 on June 30, 2026, which brought expanded agentic capabilities at lower cost. This expansion of Cowork to mobile and web mirrors the industry trend toward ubiquitous AI agents across platforms.
For Apple users, this settles whether Cowork would remain a Mac-and-Windows tool or become truly ubiquitous. You can now start delegating work from your iPhone. Whether you will actually do so at scale depends on whether your workflows rely on cloud tools or local files, and whether the doubled token limits feel forgiving enough to experiment.
