Claude Duet

Key facts: Claude Duet, announced in October 2026, is Anthropic’s agent app built on Claude Opus 5.5: instead of waiting for a prompt, it works proactively while you are away — monitoring, preparing and completing tasks, then reporting back. It is the clearest sign yet of Anthropic’s bet that the next interface is not a chat window but a colleague that works in the background.

Plans: Duet opened a waitlist preview for US Pro and Max subscribers in October 2026, with wider availability to follow. Pricing follows the underlying Claude subscription; there is no standalone Duet price announced yet.

Best for: Claude Pro and Max users with recurring research, monitoring or preparation work they would gladly hand off. Watch out: a proactive agent needs clear guardrails — what it may do unsupervised, what it must ask about, and what it must never touch.

Pros

• Works proactively while you are away, monitoring, preparing and completing tasks instead of waiting for a prompt.
• Built on Claude Opus 5.5, so it carries full Claude reasoning into background work.
• Reports back when work is done, which suits recurring research, monitoring and preparation jobs.

Watch out for

• A proactive agent needs clear guardrails: what it may do unsupervised, what it must ask about, and what it must never touch.
• It launched as a waitlist preview, so availability is limited and wider access follows later.
• Background work still needs review. Never let an agent act on sensitive accounts or data without explicit limits.

Best for

Best for: Claude Pro and Max users with recurring research, monitoring or preparation work they would gladly hand off. Who should skip it: anyone who wants a simple chat assistant, or who is not comfortable setting strict permissions for an agent that works unsupervised.

Pricing

There is no standalone Duet price announced yet. Pricing follows the underlying Claude subscription, and access opened as a waitlist preview for US Pro and Max subscribers. Check the official pricing page for current availability.
