Anthropic is testing Claude Cowork support on mobile, allowing users to manage long-running Claude tasks from their phone. Claude Cowork is Anthropic’s desktop-focused agentic mode for Claude, which can work on longer tasks, use files, create documents, generate spreadsheets, write reports, and continue working in the background while progress is monitored. Until now, Cowork has been mostly tied to Claude Desktop on macOS and Windows, but screenshots posted on X suggest Anthropic is preparing a proper mobile experience. The screenshots confirm users will be able to "start and steer tasks directly from your phone" and "check in from your phone, browser, or Claude desktop app." Anthropic notes that "work continues in the background, even when you close the app." Based on the screenshots, Claude Cowork on mobile would be similar to a remote control for Cowork on a PC, as Cowork runs directly on the computer, giving Claude access to files the user chooses to share. Anthropic has not publicly announced full mobile Cowork support yet.
