Claude Duet

Claude Duet

Claude Duet is Anthropic's proactive agent, and the difference from Claude itself is that Duet starts the conversation. It checks the apps you have connected, sends a morning brief on what needs attention, and works tasks on its own cloud computer while you are elsewhere. It runs on Claude Opus 5.5 and can draw on more than 6,000 connectors and plugins from the Claude ecosystem. Approval is required before Duet sends a message, makes a payment, signs a document or deletes a file, and it does not see passwords or logins.

Production credibility: Anthropic launched Duet on 21 October 2026 as a research preview, with access through a waitlist for US Pro and Max subscribers across iOS, Android and the web; reporting at launch indicated Team and Enterprise plans were not yet supported. Anthropic is unusually direct about the limits: Duet can misjudge urgency, is weaker at personal errands such as booking tickets, and cannot yet show you its browser. Treat it as an early product from a company that documents its rough edges rather than a finished assistant.

Key Features

• Proactive checks across connected apps rather than waiting for a prompt
• A morning brief covering what needs attention
• Tasks executed on its own cloud computer while you are away
• More than 6,000 connectors and plugins from the Claude ecosystem
• Approval gates on sending, paying, signing and deleting
• Runs on Claude Opus 5.5, on iOS, Android and the web

Ideal Use Case

People already paying for Claude Pro or Max who want the follow-through rather than the chat: the thread that needed a reply, the document that needed review, the task that would otherwise sit. The approval gates make it usable on a real inbox; the research-preview status means it should not yet be load-bearing.

How Claude Duet differentiates

Claude answers, Claude Code builds, Duet watches. Against OpenAI's Dots and Meta's Muse it is the most conservative of the cohort — approval required on every consequential action, no password visibility, and a published list of what it does badly. That conservatism is the reason to pick it and the reason it will feel slower than rivals that act first. Waitlisted, US-only and Pro or Max at launch.
