Anthropic announced yesterday that its task-oriented agent, Claude Cowork, has officially expanded to the web and mobile platforms, allowing users to seamlessly continue sessions and file operations across different devices. This feature can perform tasks across files, calendars, emails, messaging apps, websites, and other connected tools until the set goals are achieved, suitable for knowledge-based work scenarios such as data organization, document drafting, and client preparation.

Ninety percent of uses are not for coding, with operations and content creation taking up half of the market

Official data reveals an interesting fact: over 90% of the usage scenarios of Claude Cowork are not for software development, but concentrated on daily knowledge-based work. Among them, business operations and content creation are the two largest categories, accounting for about 50% of all usage, involving specific tasks such as expense verification, draft writing of difference memorandums, contract renewal tracking tables, and client material organization. This means that Claude is evolving from a "programmer assistant" into a "versatile office partner."

After this update, Cowork supports task continuation across devices. Users can start a task on the desktop and then check the progress on their phone, receiving the completed results on any device. This means you can start a data organization task on your office computer, check the progress during your commute with your phone, and continue processing at home — the task will not be interrupted when switching devices.

Background running of scheduled tasks, key decisions still require human approval

Anthropic also updated the background running capability, allowing scheduled tasks to run independently without any device being online. The official example scenario is quite appealing: users can set up customer preparation tasks on Monday mornings at 6 AM, and Claude will automatically read email clues, call records, and recent news, generate a briefing document, and draft follow-up emails but not send them yet.

In terms of interaction mechanisms, when it comes to key decisions, Claude will still proactively seek user confirmation, and confirmation requests can be directly pushed to the mobile device. The official emphasized that no content will be automatically sent before the user reviews and approves it, ensuring human final control over AI behavior. Currently, the web and mobile versions of Claude Cowork are still in testing, initially available to Max users, and the official stated that more users will be invited to test in batches in the coming weeks.
