Claude Cowork Extends to Web and Mobile, With a Persistent Thread for Cross-Device Tasks

By NewSunSEO | July 9, 2026

Anthropic is expanding Claude Cowork, the general-knowledge-work agent that launched as a desktop app earlier this year, to the web and to mobile, with a beta rollout available first to Max subscribers. The core idea is continuity across devices: a user can start a task at a desk, check progress from a phone, and return later for the completed output, even with the laptop closed.

How does Dispatch route tasks across devices?

Underneath the experience is a feature Anthropic calls Dispatch: a single persistent thread that decides which engine handles each request. Development work goes to Claude Code, knowledge work goes to Cowork, and Claude returns the result rather than narrating every intermediate step. Anthropic positions Cowork less as a coding tool and more as a background administrative coworker that only surfaces when a decision is needed.

Where is Cowork time actually being spent?

Anthropic shared early Cowork usage data drawn from 1.2 million anonymised sessions at more than 600,000 organisations during the last two weeks of May. The breakdown:

• Business process work (reconciling spreadsheets, building reports, common in finance, HR, and admin): 33.4%
• Content creation and copywriting: 16.4%
• Software development: 8.7%
• Other categories made up the remainder

Anthropic frames these figures as evidence that everyday business tasks, rather than coding, are where agentic AI is landing first inside organisations.

What role does the desktop app still play?

The desktop build remains the home for work that requires local file access or browser control. Web and mobile are designed for users who never installed the desktop client in the first place, broadening the audience beyond developers.

What are the security considerations?

Granting a phone remote control over a desktop agent introduces risk. A manipulated instruction or a phishing link could trigger actions on a host machine that are difficult to undo. Anthropic’s own guidance tells users to connect these agents only if they trust every application in the chain, a caution worth applying broadly as office suites fill up with autonomous helpers.

How does this fit the broader market?

The expansion tracks a wider industry shift from chatbots toward the surfaces where work actually runs. OpenAI has been extending Codex beyond coding toward a general enterprise-work platform. Startups are entering the same space, including Viktor, which raised $75 million to embed an AI coworker in Slack and Teams. Google is pushing in with its Gemini Spark agentic assistant, and Anthropic has been widening Claude’s reach across office software, from an integration in Microsoft Word to enterprise rollouts such as KPMG placing Claude in front of 276,000 staff.

FAQ

Dispatch is a single persistent thread that picks which engine handles each request, sending development work to Claude Code and knowledge work to Cowork, then returning the result without narrating every intermediate step.

What are people using Cowork for most?

Business process work such as reconciling spreadsheets and building reports led at 33.4%, followed by content creation and copywriting at 16.4% and software development at 8.7%, based on 1.2 million anonymised sessions across more than 600,000 organisations in the last two weeks of May.
