What is Claude Duet?
Claude Duet is a proactive AI agent from Anthropic, announced as a research preview on October 21, 2026. It runs as its own app, comes to you with what needs attention, takes on tasks by message and keeps working while you are away. Anthropic built it for professionals and small business owners with more on their plates than they can track.
How to Use Claude Duet
Join the waitlist on the Claude Duet page. Access is opening first to Pro, Max and Ultra subscribers in the US; Team and Enterprise plans are not included yet. Once you are in, install the standalone app on iOS or Android, or open it on the web at claude.ai.
Your memory, skills and connected apps carry over from your Claude account, so there is little setup. Message it by typing or voice in one ongoing thread: ask for a meeting to be scheduled, a dashboard or a sales forecast. It works in the background and notifies you when a task is done or needs your review.
Key Features
- Morning brief Each morning it summarizes the most important items across your connected apps, then stays quiet until something needs you.
- Background work It has a virtual machine with its own browser, so your laptop or phone does not need to stay on.
- Approvals for sensitive steps Before it sends a message, makes a payment, signs a document or deletes anything, it shows the action and waits for your approval.
- More than 6,000 connectors Through the Claude Marketplace it can work with Gmail, Slack, QuickBooks, Stripe, Gusto, HubSpot, Docusign, Canva and Shopify.
- Leak protection A dedicated classifier blocks requests to share credit card numbers or government ID numbers.
Why Choose Claude Duet?
The regular Claude app waits for you to open a chat. Duet reaches out first and decides what can wait, which suits people whose day is split across inboxes, calendars and invoices. It runs on Claude Opus 5.5, it never directly sees your passwords or sign-in tokens, and some actions stay off-limits even with approval, such as trading securities or moving money between accounts.
Use Cases and Applications
Business owners can have it find unpaid invoices in QuickBooks or Stripe and draft reminders, prepare payroll in Gusto, ready agreements for signature in Docusign or turn a launch into a Canva campaign. Testers quoted by Anthropic used it to catch a property showing booked on the wrong day and to move a client call that clashed with a flight.
Frequently Asked Questions
Does Claude Duet cost extra?
During the research preview it is included in Pro, Max and Ultra plans and shares the plan's usage limits with the rest of Claude. Background checks and large tasks such as building a financial model use more of those limits.
How often does it check my accounts?
It checks connected accounts every few hours rather than continuously, to avoid using up plan limits.
Can Claude Duet buy things?
Yes, with approval. It can pay through Link, Stripe's digital wallet, using a virtual card, and check out with Shop Pay.
What are its known limits?
Anthropic says it may misread a thread or misjudge urgency, personal errands such as booking tickets are weaker than work tasks, and it cannot yet show you its browser.
