Anthropic has announced Claude Duet, an always-on AI agent that can proactively manage tasks across connected apps, track emails and calendars, and keep working even when the app is closed. The assistant is rolling out as a research preview to Pro and Max subscribers in the US, with access gradually expanding through a waitlist. The feature carries no additional cost, but work performed in the background counts toward existing plan usage limits, which the company says could cause users to reach those limits sooner than with chat alone.
Claude Duet is designed to work like a person you message, whether by typing or voice. Each morning it reviews your email and calendar, identifies what most needs attention, and can begin first steps such as drafting replies for review. It runs on its own cloud-based computer, so it can continue working after users close the app. It also integrates with Stripe to check unpaid invoices and draft payment reminders, and with Link and Shop Pay to make purchases with user approval. Anthropic says it asks before sending messages, making payments, signing documents, or deleting anything.
A dedicated Tasks tab lets users track ongoing work and see which items need their attention, and the assistant posts updates to the main conversation when a task is completed or needs a decision. Only users can mark tasks as finished. Anthropic says Claude Duet is powered by Claude Opus 5.5 and is available as standalone apps for iOS and Android, as well as on the web at claude.ai, for invited users.
Claude Duet is not yet available on Team or Enterprise plans, though Anthropic plans to expand availability to those subscriptions in the future. Invitations will go out in waves.
