What this means for you

Nothing to change today if you build on the Claude API: this describes a merge of Anthropic's consumer surfaces, and no API change is mentioned. Unknown: the exact date, and whether Claude Code is affected. Pro and Max users get it first.

Anthropic is merging Claude Cowork — its agent product, which works through multi-step tasks rather than answering one question — into the main Claude chat app, so one assistant handles both. Anthropic's announcement, quoted by Simon Willison, says Claude keeps working on a task after the laptop is closed. It rolls out to Pro and Max subscribers first, on web, desktop and mobile over the coming weeks, for existing and new users. Willison writes he could not tell Cowork, Claude and Claude Code apart, and that the practical difference is still unclear.
