How much does Claude Duet cost?

Claude Duet has no separate price. Anthropic includes it in the Claude Pro and Max plans, and during the research preview it shares the plan's usage limits with the rest of Claude. Its background checks count toward those limits, and larger tasks such as financial models or decks use more of them. Team and Enterprise plans are not included yet.

Can Claude Duet spend money or send messages without asking?

No. Claude Duet shows the action and waits for your approval before it sends a message, makes a payment, signs a document or deletes anything. Some actions are off-limits even with approval, including trading securities and moving money between accounts. Duet can pay through Stripe's Link with a virtual card or check out with Shop Pay, and you can disconnect any app.

What are the known limits of Claude Duet?

Anthropic says Claude Duet may misread a thread or misjudge how urgent something is, and it can miss something that arrives between its check-ins. Personal errands such as booking tickets work less well than work tasks. Duet cannot yet show its browser, and it lives in its own app, separate from the main Claude app.

How does Claude Duet protect sensitive data?

Claude Duet handles credentials the way Claude Managed Agents does, so it never directly sees passwords or sign-in tokens. A new classifier and system prompt refuse to share the strictest tier of sensitive data, such as credit card numbers and government IDs. Health and personal finance details are shared only when you explicitly tell it to, and the app went through red teaming and an external penetration test.

What is it?

Claude Duet is a research-preview app from Anthropic in which Claude acts as a proactive agent instead of waiting for prompts. It sends a daily brief on what matters across your connected apps, alerts you only when something needs attention, and takes tasks by text or voice in one ongoing thread. Anthropic built it for professionals and small business owners with more on their plates than they can track.

How does it work?

Duet runs on Claude Opus 5.5 inside its own virtual machine with a browser, so it keeps working when your laptop or phone is off. It checks connected accounts every few hours and can use over 6,000 connectors and plugins from the Claude Marketplace, such as Gmail, Slack, QuickBooks, Stripe and Shopify. Memory, skills and connected apps carry over from your Claude account. It handles credentials like Claude Managed Agents, so it never sees passwords or sign-in tokens directly, and it uses the auto mode classifier plus prompt-injection defenses from Anthropic's browser-use research.

Why does it matter?

Most AI assistants only act when asked; this app moves Anthropic toward an agent that notices work and returns finished docs, sheets or decks for review. The approval step matters: before sending a message, making a payment, signing a document or deleting anything, Duet shows the action and waits. Some actions, like trading securities or moving money between accounts, stay blocked even with approval.
