Claude Duet 正式发布

今天，我们推出 Claude Duet 的研究预览版。这是一款全新的应用，Claude 在其中充当主动型智能体：它会主动提醒你需要关注的事项，完成你交代的任务，即使你暂时离开也会继续工作，并在代表你采取行动前征求你的确认。Claude Duet 专为事务繁多、难以兼顾的专业人士和小企业主打造。Today, we’re opening a research preview of Claude Duet, a new app where Claude works as a proactive agent. It comes to you with what needs your attention, completes tasks you ask of it, keeps working even when you step away, and checks with you before it acts on your behalf. We built Claude Duet for professionals and small business owners with more on their plates than they can track.

它可作为独立应用在 iOS 和 Android 上使用，也可在 claude.ai 上使用。在本次研究预览期间，Claude Duet 已包含在 Pro 和 Max 计划中，使用额度与 Claude 的其他功能相同。如需体验，请加入候补名单（将在新标签页中打开）。It’s available as a standalone app on iOS and Android, and on claude.ai. For this research preview, Claude Duet is included in Pro and Max plans and uses the same usage limits as the rest of Claude. To get access, join the waitlist (opens in new tab).

Put your attention where it matters most

We designed Claude Duet to be a partner you can trust. Professionals of all kinds have to juggle many decisions a day, and we think they’ll find Claude Duet most useful. It helps you prioritize where to spend your time and energy, and to leave room for the ambitious projects that felt impossible or daunting before.

What makes Claude Duet so helpful is its judgment. We designed it around Claude Opus 5.5 (opens in new tab) and built it to be resourceful and to decide what needs you, what can wait, and when to check with you first.

Each morning, it sends you a short brief on the most important items across your connected apps. Throughout the day, it keeps tabs on those apps and messages you only when something needs your attention. You can also hand it tasks of all shapes—from simple administrative tasks of scheduling meetings to more complex ones, such as building dashboards with dozens of tools, creating financial or sales forecasts, prototyping, and building web apps.

Safety and discretion are built in

Claude Duet draws on years of security, safety, and privacy work on agents, both our own and the infrastructure businesses use to run theirs:

• Claude Duet draws on our framework for trustworthy agents (opens in new tab), which also guides agents like Claude Code and Claude in Chrome.
• Claude Duet’s handling of credentials follows the design we use for Claude Managed Agents (opens in new tab), so it never directly sees your passwords or sign-in tokens.
• Actions are approved by our auto mode classifier (opens in new tab), the same safeguard that protects Claude and Claude Code from taking steps you didn’t ask for.
• Claude Duet’s defenses against hidden instructions and prompt injection come from our browser-use research (opens in new tab), and our models and safeguards also cover this more broadly.
• We run adversarial tests for Claude Duet’s security infrastructure. Red teams and an external firm penetration tested Claude Duet, and it’s covered by our public bug bounty program (opens in new tab).

How Duet handles sensitive information. We’re also releasing Claude Duet with a new dedicated classifier and safety system prompt that checks each message and guards against leaks of sensitive information. An agent that reads email and sends messages for you is constantly deciding where information should go. This new classifier and prompt are designed to reject requests to share the strictest tier of information, including credit card numbers and government identification. Other sensitive information, such as health or personal finances, are let through only when you’ve explicitly instructed Claude Duet to send it.

We’re continuing to develop and strengthen these protections, and will share more details about how Claude Duet is designed for safety in the coming days.

How testers are using Claude Duet

People at Anthropic have been using Claude Duet to accomplish more, but also to leave more room for thinking and being present. Boris Cherny, who leads our Claude Code team, talks through his mental to-do list with Claude Duet on walks, instead of saving the work for his desk. Chelsea Larsson, who leads our model and product behavior design team, hands Claude Duet her to-do list before leaving to be with her kids and it saves the results for an evening report. And the team behind Claude Duet uses it to build the product. Karan Ahuja, who leads the team, works with it to schedule user interviews, partner with him on prototypes, and even ship code.

We gave small business owners and entrepreneurs early access to Claude Duet, and some have been using it to help run their businesses. Here’s what some of them said:

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.

We’re starting today with Pro and Max users in the US. Join the waitlist (opens in new tab) and we’ll email as soon as Claude Duet’s ready for you.
