Claude Cowork: Tasks Keep Running After You Close the Laptop

Anthropic's new Claude Cowork feature extends Claude Code's agentic capabilities into broader knowledge work. Once a task is assigned, work keeps running on Anthropic's servers even after the laptop is closed, with sessions and files persisted to the user's account and accessible again from desktop, web, or mobile. This marks a shift from turn-based chat interaction toward asynchronous execution, where users define a goal and later review completed work rather than staying present throughout.

Anthropic is explicit about the limits: complex tasks consume more usage allocation, tasks needing local files or browser access still route through Claude Desktop, computer-use features carry risks around screenshots and app permissions, and local sessions can stop if the machine sleeps — only remote sessions truly persist. The company also notes that computer use remains experimental and recommends starting with low-risk tasks.

The real significance isn't speed but a structural shift in the human-AI collaboration model: from synchronous prompting to asynchronous delegation, where humans set goals, define boundaries, and review outcomes instead of supervising every step. For engineers, this highlights the design requirements for agentic systems — permission controls, process visibility, and human review layers — as AI moves from chat responder to persistent work unit.
