# Anthropic Expands Claude Cowork to Mobile and Web with Background Tasks

> Anthropic has brought Claude Cowork to iOS, Android, and the web for the first time, and the headline feature is that its tasks now run in the background. You can hand off a job, close the app, and let it continue in the cloud, with connectors for Microsoft 365 that include write access to email and calendar rather than read-only glances. The move nudges the assistant away from the chat-window model toward something that behaves more like a coworker running errands while you do other things. Write access to real inboxes and calendars is the meaningful step here, and also the riskier one, since an agent that can send mail and book time is an agent that can make consequential mistakes. One detail cuts against the usual framing: Anthropic reports that across 1.2 million anonymized sessions, under 9 percent involved software development. The tasks people reach for Claude to do are increasingly ordinary knowledge work, not coding, which says a lot about where everyday AI is actually headed.
