AI company Anthropic has expanded its Claude Cowork platform to mobile devices and the web, marking a major step in the evolution of AI assistants designed to handle everyday workplace tasks.

The feature, which first launched as a desktop application in January, is now being rolled out in beta for web browsers and the Claude apps on iOS and Android. Initial access is being provided to Max subscribers, with broader availability expected later.

Work continues even when devices are offline

One of the biggest additions is the ability for users to assign tasks and monitor progress without keeping their computers running.

Anthropic said users can start a task on their desktop, leave the office, and continue tracking the job from their smartphones. Claude Cowork can keep working in the background even after a laptop is closed, while scheduled tasks can run automatically without any device remaining online.

If a task reaches a point where human input is needed, the system can send a notification to the user’s phone. Users can then provide instructions, answer questions or change the direction of the task remotely.

Desktop remains the most powerful version

While mobile and web access add convenience, Anthropic said the desktop application will remain the most capable version of Claude Cowork.

The desktop edition can access local files, browser activity and other resources that are not available through mobile devices. However, bringing Cowork to the web means users can now access the service without installing dedicated software.

Anthropic is also integrating traditional Claude conversations and Cowork tasks into a unified interface, allowing projects, files and ongoing work to remain synchronized across devices.

AI assistants are moving beyond coding

The expansion reflects a broader trend in the artificial intelligence industry, where AI tools are increasingly being used for administrative and knowledge-based work rather than just programming.

Claude Cowork can interact with emails, calendars, documents, messaging platforms and online resources to complete assigned tasks. Similar efforts are also being pursued by OpenAI, whose Codex platform is being used for reports, research, presentations and data analysis in addition to software development.

New data reveals how businesses use AI

Anthropic also released data from 1.2 million anonymized Cowork sessions across more than 600,000 organizations during the final two weeks of May.

According to the company, business operations accounted for 33.4 percent of usage, making it the largest category. These tasks included compiling reports, creating onboarding checklists and managing spreadsheets.

Content creation and copywriting represented 16.4 percent of activity, while software development made up just 8.7 percent. More than 90 percent of Cowork usage involved non-coding tasks.

The findings suggest that businesses are increasingly turning to AI for routine administrative work, helping employees save time and focus on higher-value responsibilities as workplace automation continues to expand.
