Claude Duet Explained: Anthropic's New Proactive AI Agent (Features, Price, Waitlist & How It Works)

On October 21, 2026, Anthropic announced Claude Duet, a new AI agent that doesn't wait for you to open a chat. Instead, it reaches out with what needs your attention, completes tasks, and keeps working after you put your phone down. It is currently a research preview with access by waitlist.

What Is Claude Duet?

Claude Duet is a standalone Claude experience described by Anthropic as a research preview of Claude that you message the way you'd message a person. It is a proactive agent, which means it monitors your connected apps, spots what needs your attention, and messages you first.

In Anthropic's words, it "comes to you with what needs your attention, completes tasks you ask of it, keeps working when you step away, and checks with you before it acts on your behalf."

Who Is Claude Duet For?

Anthropic says it built Duet for professionals and small business owners with more on their plates than they can track. The company also says that because Duet is designed mainly for the workplace, personal errands such as booking tickets are not "quite as strong."

Key Features

• Morning brief: Duet briefs you every morning, drafts next steps, and then stays quiet until something needs you.
• Proactive alerts: It keeps tabs on connected apps such as email and calendar and suggests things that need attention.
• Task completion: It can build dashboards, schedule meetings, and create financial forecasts, according to CNBC.
• Works in the cloud: Duet runs on its own cloud-based computer with its own browser, so it can keep working after you close the app.
• One conversation: Duet keeps a single conversation and adds updates as tasks progress or new issues appear.
• Approval before action: It checks with you before it acts on your behalf.
• Your Claude context: It uses the same memories, skills, and connectors as your regular Claude account and can search past conversations, so setup is light.

What Model Powers Claude Duet?

Duet is built on Claude Opus 5.5. Anthropic says it chose this model because the product depends on judgment across several stages, such as spotting relevant events, estimating urgency, choosing tools, and deciding when to involve the user.

Who Can Use Claude Duet Today?

How Much Does Claude Duet Cost?

Anthropic has not announced a separate price. Duet shares your plan's usage limits with the rest of Claude, and its background checks count toward those limits. Larger tasks, such as building a financial model, use more of your allowance.

Is Claude Duet Safe?

Anthropic says Duet:

• Does not see your passwords or logins when given access to accounts
• Has a dedicated classifier and safety system prompt that checks each message to guard against sensitive information leaks
• Asks for your approval before taking sensitive actions

Anthropic also warns that Duet is early and "might misread a thread or miscalibrate what's urgent." Review what it drafts or plans to do before approving.

Claude Duet vs OpenAI Dots vs Meta Muse

Claude Duet joins a new category of "always-on" agents. Press coverage describes it as Anthropic's answer to Meta's Muse and OpenAI's Dots. All three are proactive agents that reach out before you ask. Based on reporting so far, what stands out about Duet is that it:

• Is aimed at professionals and small business owners
• Runs on Opus 5.5
• Reuses your existing Claude memory, skills, and connectors
• Is currently invite-only for Pro and Max users in the US

Wait for independent hands-on reviews before comparing quality, because the products are all brand new.
