Anthropic Expands Claude Cowork to Mobile and Web

Anthropic Expands Claude Cowork to Mobile and Web">

Claude Cowork, Anthropic's Claude Code-style agent for general knowledge work, is now available on web and mobile for Max subscribers. The app launched as a desktop version in January, but as of Tuesday, users can access it across devices, enabling them to start a task on their desktop, receive status updates on their phone, and pick up where they left off later, even if their laptop is closed. Anthropic aims to position Cowork as an agentic administrative coworker that can work in the background, sync across devices, and request human input when needed.

This move signals a shift towards making AI-powered tools a seamless part of everyday work. The expansion comes as AI firms, including OpenAI, push their products beyond chatbots into the surfaces where work actually happens. OpenAI's Codex, initially a software development tool, is now used by non-developers for tasks like reports, spreadsheets, and presentations.

Launching Cowork as a multi-platform app allows the agent to continue running tasks in the background without requiring a device to be online. For example, users can instruct Cowork to prepare a client's briefing document by working through email threads, transcripts, and recent news, and then draft a follow-up email. The desktop app will remain the go-to platform for deep work, where Claude can access local files and the browser.

However, bringing Cowork to web and mobile makes it accessible to users who didn't install the app. Anthropic plans to unify chat and Cowork on web and desktop, with projects and artifacts living together across both. Anthropic released early Cowork data, which suggests the tool's primary use case is handling tasks that keep companies functioning, such as business process operating and content creation.

The study analyzed 1.2 million anonymized Cowork sessions from over 600,000 organizations. The largest category of tasks, at 33.4%, was business process operating, including pulling updates into a single report, building onboarding checklists, and reconciling spreadsheets. Content creation and copywriting accounted for 16.4% of tasks, while software development made up 8.7% of Cowork usage.

"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 in a statement. "Our goal is to make this a reference point for people who are figuring out how to integrate AI products into their daily work, and to show where value is most concentrated." Why this matters: The expansion of Claude Cowork to mobile and web marks a significant step in the development of AI-powered tools for everyday business work. As AI firms continue to push their products beyond chatbots, the competition for ownership of the workspace where work gets done is heating up.
