Anthropic expands Claude Cowork agent tool to web and mobile

Claude Cowork was introduced as a desktop feature that lets users hand off multi-step tasks to an AI agent, which works across files, calendars, email, messaging, and web tools until completion. The new web and mobile expansion makes the tool accessible from more devices, though Anthropic maintains that desktop remains the full-featured version for sustained work. The company's own usage data reveals a meaningful gap between the tool's initial positioning—as a code-generation aid—and how customers actually deploy it. By revealing that over 90% of real-world Cowork sessions serve administrative and creative tasks outside software development, Anthropic is signaling that the business case for AI agents extends well beyond engineering workflows. These 'work around work' tasks—expense reconciliation, document synthesis, administrative coordination—consume substantial employee hours despite being invisible in formal job descriptions, suggesting a large addressable market for AI agents in business operations.
