How Claude Duet works

Your context from Claude is the foundation. Claude Duet carries over your memory, skills, and connected apps from your Claude account, so setting it up requires minimal work. What changes is how you work together: Claude Duet comes to you first, and you can message it through typing or voice in one ongoing thread, so a quick reply and a weeklong project both start in the same place.

Work continues when you step away. Claude Duet has a virtual machine with its own browser, so it doesn’t require your laptop or phone to be on. Describe a task in a short message, and it works out which apps to use and what steps to take in the background. You’ll receive a notification when the task is complete or needs your review.

Receive a message when something needs you. Claude Duet checks your connected accounts every few hours, because checking nonstop would use up your plan’s limits much faster. We’re continuing to test its judgment about when to message you, and we’ll keep tuning it based on what testers tell us. You can also tell it what you want to hear about and how often.

Important decisions stay with you. Claude Duet reads, drafts, and prepares work on its own. But before it sends a message, makes a payment, signs a document, or deletes anything, it shows you exactly what it’s about to do and waits for your approval. A few things are off-limits even with your approval, like trading securities or moving money between accounts. You’re also able to disconnect any app Claude Duet has access to.

Connect with the tools your business runs on. Claude Duet can use the over 6,000 connectors and plugins in the Claude Marketplace (opens in new tab) to:

• Find the Gmail and Slack messages you’ve missed and help you reply.
• Check Intuit QuickBooks or Stripe for unpaid invoices and draft reminders.
• Prepare and run payroll in Gusto, with hours, bonuses, and reimbursements filled in.
• Draft a job posting and, once you edit and approve, post it to LinkedIn.
• Help prepare agreements and send them for review and signature through Docusign.
• Draft follow-up emails using the contact and deal history in HubSpot.
• Turn your product launch into a social campaign in Canva.
• Set up, design, and manage your Shopify store. Coming soon, a richer visual editor will let you design your storefront and preview it before anything goes live.

You can also use Claude Duet to purchase things for your business using Link, Stripe’s digital wallet. Claude Duet confirms the item with you, and Link asks you to approve the spend. It then pays with a virtual card, so your real card number isn’t shared. It can also use Shop Pay from Shopify to check out at online stores. Coming soon, with your permission, it will be able to sign in to sites with logins you’ve saved in 1Password.

Join the research preview

This is an early version of Claude Duet, and it still might misread a thread or miscalibrate what’s urgent. We built its core functionality around work, so personal errands, such as booking tickets, aren’t quite as strong, and it can’t yet show you its browser. For now, Claude Duet lives in its own app, separate from the main Claude app. What we learn from early users will shape how the two work together.

During the research preview, Claude Duet shares your plan’s usage limits with the rest of Claude, and it uses them differently than a typical conversation does. Its background checks count toward those limits, and larger tasks, like building a financial model or a deck, require more model turns and background work.
