Anthropic introduces Claude Duet, a work-focused AI agent launching in preview

Anthropic announced Claude Duet on October 21, 2026, adding a new agent to the competition with OpenAI's Dots and Meta's Muse. The Verge reported that the product is aimed at professionals and small business owners and is launching as a research preview.

The emphasis is work rather than personal errands, according to The New York Times. That focus makes Duet a tool for handling ongoing responsibilities, not just answering individual requests.

The October 21 announcement introduced an assistant that can proactively manage tasks across connected apps. 9to5Mac reported that Duet can keep track of emails and calendars and continue working even when the app is closed.

Preview details published the same day put Opus 5.5 at the centre of the product. According to TestingCatalog, Duet uses it for morning briefs and background tasks.

That coverage also described limits on how the agent operates. TestingCatalog reported that Duet shares plan limits and requires approval before key actions.

Access was restricted at launch. Engadget reported on October 21 that Anthropic subscribers in the US could join a waitlist to try the agent, while TestingCatalog identified US Pro and Max users as the preview audience.

Claude Duet is an announced product in a limited research preview, not a broadly available release. Both The New York Times and 9to5Google reported that it was not yet widely available.

Its main promise is continuity: an assistant that follows activity in connected services and works in the background. The approval requirement reported by TestingCatalog also means that background operation should not be read as unrestricted permission to act.

The immediate next step is access through the US subscriber waitlist described by Engadget. The supplied coverage gives no timetable for wider availability or expansion beyond the US.

The practical questions are how shared plan limits affect ongoing tasks and which actions require approval. TestingCatalog identifies both constraints, but its coverage summary does not spell out their full scope.
