Claude Cowork and chat merge into one Claude, rolling out to Pro and Max first

Anthropic is folding Claude Cowork and chat into a single Claude, starting with Pro and Max plans in the Claude app on web, desktop and mobile over the coming weeks. The evidence covers the merge and the rollout order, but not what changes in features or surfaces.

Claude Cowork and chat become one Claude. According to the source, existing and new Pro and Max users get it first, in the Claude app on web, desktop and mobile, rolling out over the coming weeks rather than all at once.

The practical difference the source claims is continuity of work: a quick question or a report due at noon can be handed over, and Claude continues even after the laptop is closed. That is the general-agent framing, and it is the only concrete capability detail in the evidence.

What the merge actually changes in features and surfaces is unresolved. The source notes it was already confused about the boundaries between Cowork, Claude and Claude Code, and expects working out what the merge means to take real effort. Treat the announcement as a rollout notice, not a feature list.

Our reading

For anyone who has been guessing which Claude surface to open for a given job, the merge removes a naming decision but not the underlying question of what each surface can now do. Teams on Pro or Max should care first, because they are the ones who will see it. The announcement is a rollout, so it belongs in a release watch, not a capability review.

What to do or watch

Pro and Max users should watch the Claude app on web, desktop and mobile over the coming weeks for the merged experience, and note which work they can hand off and leave running. The precise feature and surface changes remain the open question.
