Overview

Bottom line

Claude Duet is a proactive agent app from Anthropic, opened as a research preview on October 21, 2026. You message it the way you would message a person; it checks your connected accounts every few hours, prepares briefs and drafts, and works on its own cloud computer on Claude Opus 5.5. Before it sends a message, makes a payment or signs a document, it shows you exactly what it is about to do.

It suits professionals and small business owners with more threads than they can track who already pay for Claude. The core caveat is limits: Duet uses the same five-hour and weekly limits as chats in Claude, and its background checks count too, so heavy use leaves less for everything else on the plan.

There is nothing separate to buy. During the preview Duet is included with Pro and Max for US accounts, through a waitlist that invites people in waves.
