Claude Duet

Claude Duet is Anthropic's proactive personal agent. Instead of waiting for you to type, it checks your connected accounts (email, calendar, accounting, CRM) every few hours, sends a morning brief, and works on tasks you assign while you are away, running on its own cloud computer so your laptop can be off. It reads, drafts and prepares on its own, but stops for your approval before it sends a message, makes a payment, signs a document or deletes anything. Anthropic opened a waitlist on October 21, 2026, as a research preview starting with Pro and Max subscribers in the US. It uses your normal plan limits and is not part of Team or Enterprise plans yet.
