An agent for knowledge work that completes tasks across selected files, browsers, and connected tools, producing deliverables for review.
Cowork launched as a research preview in January 2026, bringing Claude’s ability to carry out tasks into a desktop experience. The goal was to work directly with selected files and tools, returning work for review rather than leaving the user to transfer an answer out of a chat. Its capabilities expanded across scheduled tasks, browser work and longer projects. Anthropic later began merging Cowork and chat into a single Claude conversation, so working with files could become part of the same interaction rather than a separate mode a person had to choose in advance.
