Anthropic merges Claude Cowork and chat into one product

Rollout begins with Pro and Max plan users on web, desktop, and mobile.

Sourced from Simon Willison's WeblogThis month

Anthropic is collapsing two separate products into one. Claude Cowork and Claude chat are merging into a single Claude, rolling out first to Pro and Max plan users across web, desktop, and mobile over the coming weeks. The unified product handles both quick questions and longer delegated work, including tasks that continue after a user closes their laptop.

Simon Willison's Weblog flagged the move and noted the parallel to OpenAI renaming its Codex desktop app to ChatGPT weeks earlier. Both labs are consolidating fragmented product lines under single, general-purpose agent identities. The confusion between Cowork, Claude, and Claude Code was real enough that Willison had planned a dedicated explainer piece.

Watch whether the unified surface actually delivers on background task execution, or whether the merge is mostly a branding simplification. The feature boundary between chat and agent modes is still not fully defined, even post-launch.

Analysis

Consolidation over proliferation: the lab that ships five surfaces loses to the one that owns a single trusted entry point. Watch whether capability follows the rebrand or just precedes it.
