Claude Cowork is moving beyond the desktop. Anthropic’s Claude Code-style agent for general knowledge work launched as a desktop app in January, and starting Tuesday it is available on web and mobile for Max subscribers.
The expansion is more than a device update. It points to a larger shift in AI products: agents are being designed less like chat windows and more like persistent coworkers that can keep working across the places where people actually do their jobs.
Claude Cowork moves across devices
With the new web and mobile access, Anthropic wants Claude Cowork to follow a task from one screen to another. A user can begin something at a desk, receive status updates on a phone, and return to the completed output later, even if the laptop is closed.
That matters because many work tasks do not fit neatly inside one sitting. A briefing, report, spreadsheet check, or draft can require background processing, later review, and occasional human judgment. Cowork is being positioned for that kind of handoff.
The desktop app remains the place Anthropic describes as suited for deep work, including access to local files and the browser. But bringing Cowork to web and mobile also lowers the barrier for people who did not install the desktop app. Anthropic says chat and Cowork will be unified in web and desktop to start, with projects and artifacts living together across both.
From coding agent to administrative coworker
The product’s roots are in the Claude Code-style model of agentic work: give the system a task, let it operate in the background, and intervene when a human decision is required. But the new positioning is broader than software development.
The expansion suggests Anthropic wants Cowork to feel less like a coding tool adapted for non-coders and more like an agentic administrative coworker. In practice, that means a system that can continue running tasks, move across devices, and ask for input when it reaches a point only the user can decide.
Anthropic gives one example involving client preparation: Claude works through email threads, transcripts, and recent news, creates a briefing document, and leaves a follow-up email drafted but unsent for the user to review. The important detail is not just that the agent drafts material. It is that the user remains responsible for the final action.
This is the broader office use case AI firms are chasing. The goal is not simply to answer questions inside a chatbot. It is to take on multi-step work that normally lives across email, documents, spreadsheets, research, and internal communication.
The coding agent wars enter everyday work
The move also reflects a wider competition among AI firms. The source article frames it as the coding agent wars spilling into the rest of the office. Tools that began with software development are now being aimed at reports, presentations, research, data analysis, communications, and other general business tasks.
OpenAI has made a similar move with Codex, which began as a software development tool but is increasingly being used by non-developers for reports, spreadsheets, presentations, research, data analysis, and more. For both Anthropic and OpenAI, the competitive question is shifting. The key advantage may depend less on who has the best chatbot and more on who owns the work surface where tasks get done.
Anthropic’s push also reaches into Slack. The company recently launched Claude Tag, an always-on Claude that lives in Slack and acts as an AI teammate. Together with Cowork’s web and mobile expansion, that shows a strategy built around presence: the agent is meant to be available where work is already happening, rather than waiting inside a separate tool.
Early usage points to work around the work
Anthropic also released early Cowork data that helps clarify where the tool is being used. The company sampled 1.2 million anonymized and aggregated Cowork sessions from more than 600,000 organizations over the last two weeks of May.
The clearest pattern was not software development. Instead, Anthropic said Cowork is being used for the “work around the work” that keeps companies functioning. These are tasks that may be common across many roles but are not always the core responsibility of the person doing them.
The largest category, at 33.4%, was business process operating. The examples included pulling scattered updates into one report, building onboarding checklists, and reconciling spreadsheets. Anthropic said those tasks are common among roles in finance, HR, and administration.
The next largest category, at 16.4%, was content creation and copywriting. That included drafts, slide decks, social posts, proposals, and other communications work usually performed by marketing and management positions. Software development accounted for 8.7% of Cowork usage.
Those numbers help explain why mobile and web access matter. If Cowork is mainly helping with administrative, communications, and process work, then it needs to fit into the rhythm of office life. That rhythm often includes checking progress away from a desk, reviewing outputs later, and making decisions between meetings.
What this signals for AI at work
The practical takeaway is that AI agents are being pulled into the ordinary layers of business operations. The tasks described by Anthropic are not exotic. They are the recurring jobs that connect teams, prepare meetings, organize information, and turn scattered inputs into useful outputs.
That also explains the importance of background execution. If an agent can continue working without a device online, it becomes less dependent on a single session. It can function more like a delegated task than a chat exchange.
For organizations, the early Cowork data suggests that value may concentrate in the operational middle of work: not only writing code, and not only generating text, but coordinating information into usable documents, checklists, spreadsheets, and communications. That is where Anthropic appears to see momentum.
The broader implication is straightforward. AI products are moving from being tools people open when they have a prompt to being systems that stay attached to workflows. Claude Cowork’s move to web and mobile is one step in that direction.
