Anthropic Expands Claude Cowork to Mobile and Web, Agent Use Data Reveals Business Operations as Top Use Case

Anthropic announced today that Claude Cowork is expanding beyond the desktop app to mobile and web, allowing users to start tasks at their desk, check status on their phone, and pick up finished output even when their laptop is closed. The expansion signals Anthropic's ambition to transform Cowork from a coding tool into a full administrative AI collaborator.

With the multi-platform launch, Cowork can continue running tasks in the background without requiring any single device to stay online. Anthropic illustrates the use case with a scenario: "Set Monday's client prep for 6 am: Claude works through the email threads, transcripts, and recent news, builds the briefing doc, and leaves the follow-up email drafted but unsent. Review it over coffee."

The desktop app remains the place for deep work where Claude can access local files and the browser. But adding web and mobile means users who never installed the desktop app can also access Cowork. Anthropic says chat and Cowork will be unified into a single interface.

Notably, Anthropic also released early Cowork usage data. The study sampled 1.2 million anonymized and aggregated Cowork sessions from over 600,000 organizations during the last two weeks of May. The largest category at 33.4% was business process operating — pulling scattered updates into a single report, building onboarding checklists, and reconciling spreadsheets — common among finance, HR, and administrative roles.

The second largest category at 16.4% was content creation and copywriting: drafts, slide decks, social posts, proposals, and other communications work typically handled by marketing and management. Software development, while still a prominent use case, was overtaken by business operations in share.

"While coding is still — understandably — one of the uses of AI that gets the most attention, the use of AI for everyday business work is on the rise, and the kinds of tasks people are finding it most helpful for are coming into focus," Anthropic said. The data suggests AI agents are expanding from developer-focused tools toward roles across the entire organization.

Anthropic also recently launched Claude Tag, an always-on Claude that lives inside Slack as an AI teammate. Together, these product moves outline a strategy of embedding Claude into the surfaces where work actually happens — beyond the chat interface.

In a competitive agent market that includes OpenAI Codex, Microsoft Copilot, and Google Gemini Agents, Anthropic is betting on a differentiated positioning for Cowork as an administrative collaborator focused on background execution, cross-device continuity, and natural-language-driven task management rather than pure coding assistance.
