Claude Cowork expands to mobile and web

Anthropic has expanded Claude Cowork, its agent for general knowledge work, to web and mobile platforms for Max subscribers, moving beyond its initial desktop-only release in January. The update allows users to start a task on their desktop, check status updates on their phone, and retrieve the completed output later, even if their laptop is closed.

This expansion signals Anthropic’s intent to position Cowork as an administrative coworker that works in the background, follows across devices, and requests human input only when a decision is needed. It reflects a broader industry trend where AI companies push products beyond chatbots into everyday work environments. OpenAI has similarly expanded Codex, originally a developer tool, to be used by non-developers for reports, spreadsheets, and presentations.

Anthropic released early Cowork usage data based on 1.2 million anonymized sessions from over 600,000 organizations in the last two weeks of May. The largest category, at 33.4%, was business process operations: tasks like compiling scattered updates into a single report, building onboarding checklists, and reconciling spreadsheets. The second-largest category was content creation and copywriting at 16.4%, including drafts, slide decks, and social media posts. Software development accounted for only 8.7% of usage.

The company states that while coding receives much attention, everyday business use of AI is rising, and the most helpful tasks are becoming clearer. The desktop app remains the primary interface for deep work, but the web and mobile expansion makes Cowork accessible to those who have not installed the app.
