This Claude Duet review covers Anthropic’s new proactive agent app, which the company announced on October 21, 2026. Duet is in a research preview behind a waitlist. This article is therefore based on what Anthropic and the press have published, not on hands-on use.
The short version is that Duet 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. The sections below of this Claude Duet review cover what it does, who can use it, what it costs and what is still unknown.

Claude Duet Review: What the App Is
Anthropic describes Duet as a new app where Claude works as a proactive agent. You message it the way you would message a person, either typed or spoken. It works in the apps you’ve connected and is designed to ask before it sends a message, makes a payment, signs a document, or deletes anything.
It is a standalone product. It reuses memory, skills and connected apps from your Claude account, and you interact with it in one ongoing thread instead of separate conversations.
Who Claude Duet Is For
Anthropic says it built Duet for professionals and small business owners with more on their plates than they can track. The company positions it as a workplace tool. TechCrunch reports that Duet isn’t good at errands or booking tickets, and that it can’t show you its browser use as it happens.
If you want a consumer errand-runner, this is probably not it. If you want something that watches your inbox, calendar and business apps, it fits the brief. For background on how agents are changing small-business operations, see our piece on AI agents for small business.
Key Features Confirmed So Far
Morning briefs and background checks
Duet sends a short brief each morning on important items from connected apps. It then checks those apps every few hours and sends an alert when something needs attention. This is the “proactive” part that separates it from a normal chatbot.
Work in the cloud
It completes tasks and can work in the cloud without local access to your computer. It has a virtual machine with its own browser. It can finish tasks in the background and come back to you if it needs approval.
What it can produce
CNBC lists daily briefs, tracking connected apps, building dashboards, scheduling meetings and creating financial forecasts. MacRumors adds simple administrative tasks and more complex jobs such as building web apps.
Model and connectors
Duet is built on Claude Opus 5.5 and can connect to over 6,000 connectors and plug-ins in the Claude Marketplace, according to TechCrunch. To compare that model with newer options, see Claude Fable 5.1 vs Opus 5.5.
Purchases
Duet can buy online for you through Stripe’s Link wallet or Shopify’s Shop Pay. Sensitive steps such as payments need your approval, and it won’t trade securities or move money between accounts.
Safety and Privacy Design in Our Claude Duet Review
Duet does not see passwords or logins when given access to accounts. It also has a dedicated classifier and safety system prompt that check each message for sensitive information leaks. The approval step before sending, paying, signing or deleting is the main safeguard.
These are Anthropic’s claims, and nobody has independently verified them yet. If you use agents in the EU, read our guide to EU AI Act compliance for AI agents before connecting business data.
Pricing and Availability
This part of the Claude Duet review is simple, because there is no separate price. During the research preview, Duet is included in Pro and Max plans and uses the same usage limits as the rest of Claude. Background work counts toward those limits, which Anthropic says could make you hit them sooner than with chat alone.
Access is limited in these ways:
- It is a research preview with access granted through a waitlist, limited to Pro and Max subscribers in the United States.
- Invitations go out in waves, and Duet isn’t available on Team or Enterprise plans yet.
- Platform details differ between sources. Anthropic says it is a standalone app on iOS and Android and on claude.ai. MacRumors mentioned only an iOS app alongside the web, so check Anthropic’s page for the current status.
Limitations to Weigh
- Waitlist and US-only access. Most readers of this Claude Duet review cannot try it today.
- Shared usage limits. Background checks consume your plan allowance, so heavy use may cost you chat capacity.
- Not for personal errands. Anthropic has said so directly.
- Preview status. Behavior and features may change.
- No team plans. Teams on Team or Enterprise cannot use it for now.
Alternatives: Muse and OpenAI Dots
Duet enters a crowded field. Meta’s Muse launched last month and rose to the top of Apple’s App Store. OpenAI introduced Dots, its “always-on agents,” at its developer conference weeks later. CNBC notes that Meta has marketed its agent mainly to consumers, while OpenAI’s product straddles enterprise and consumer markets.
For the developer angle on Dots, see our article on OpenAI Dots. A fair side-by-side needs hands-on access to all three, which this Claude Duet review does not have.
What We Don’t Know Yet
Several things are not yet public or verifiable. There are no independent benchmarks or hands-on reviews, and no confirmed timeline for general availability or for Team and Enterprise plans. We also don’t know how quickly background checks use up plan limits, because that depends on your usage.
Until real-world reports arrive, treat any strong claim about reliability with caution. A later Claude Duet review will be more useful once people have used it for weeks.
Verdict: Is It Worth Joining the Waitlist?
For US-based Pro or Max subscribers who handle a lot of email, meetings and app notifications, joining the waitlist costs nothing extra. Duet is included in your plan, and the approval-before-action design is a sensible default for an agent that acts for you.
For everyone else, wait. This Claude Duet review rests on official documentation and press coverage, so it can’t judge accuracy, speed or how well the agent copes with messy real inboxes. Check back after more users have tested it.
