Anthropic launched Claude Duet on October 21 as a waitlisted research preview, adding a cloud-based agent to a fast-growing field of AI assistants designed to keep working after a user leaves the chat. The separate app is available to eligible U.S. Pro and Max subscribers, according to the source material; Anthropic says it can handle tasks across connected services while requiring approval for sensitive actions.

Duet runs in a virtual cloud computer with its own browser, so tasks can continue while a user’s phone or laptop is off. Users can send instructions by text or voice in an ongoing thread. Anthropic says the agent can prepare a morning brief, flag items needing attention, schedule meetings, and build items such as dashboards, sales forecasts or small web apps. It carries over memory, skills and connected apps from a user’s Claude account.

Anthropic says Duet can connect to more than 6,000 connectors and plugins in the Claude Marketplace. Its examples include finding unpaid invoices in QuickBooks or Stripe, handling payroll in Gusto, working with agreements through DocuSign and assisting with Shopify storefronts. For purchases, Anthropic says Duet uses Stripe’s Link wallet and a one-time card limited to a specific merchant and amount.

Anthropic’s safety post, published October 23, says Duet pauses for approval before sending potentially sensitive messages, making payments or deleting items. The approval screen shows the action, destination and content, including recipients. The company says a separate classifier checks whether an action matches the user’s intent. Trading securities, transferring money between accounts and accessing another person’s account are prohibited, even with user approval. These safeguards are Anthropic’s descriptions; the source material reports no independent testing of the preview.

The Race Moves Beyond Chat

Duet’s launch adds Anthropic to a competition over AI agents that can operate continuously, use connected software and return with completed work or requests for input. For users, the promise is less time spent moving information between apps and more work handled in the background. The practical value will depend on whether the agent completes tasks accurately and whether its checks make it safe to delegate them.

The race also concerns who controls the route between a customer, their data and the AI models doing the work. The source material says SpaceXAI’s Grok Bot can route tasks to other companies’ models, including Claude Opus 5.5, and that customers cannot choose the model through a customer-facing picker. If agents increasingly rely on models from multiple providers, control of the interface, connected accounts, memory and usage limits may matter as much as the underlying model. That is a competitive possibility, not a settled outcome.

For businesses, background access to invoices, payroll, contracts and communications creates operational and privacy risks as well as potential time savings. A cautious pilot can reveal whether an agent’s outputs are useful, what data it reaches and how often people approve actions without checking them.

How Duet Fits the Launch Race

Anthropic entered a sequence of agent launches described in the source material: SpaceXAI opened the Grok Bot beta on August 11, Meta launched Muse on September 8, OpenAI introduced Dots at DevDay on September 29, and Google released Gemini Agent on October 8, according to TechTarget. Anthropic announced Duet on October 21. The products share a broad pitch: an assistant can work on a cloud computer, retain context and contact the user when a task is complete or needs attention.

Duet is built on Claude Opus 5.5, according to the source material, and is offered as a separate app on iOS, Android and claude.ai. Its early availability is limited by a waitlist and subscription eligibility. The launch therefore does not establish broad public access, or show how the system performs under routine use.

Anthropic also describes limitations: Duet checks connected accounts every few hours rather than continuously, partly to limit usage. It may misread a conversation or judge urgency poorly, is less capable with personal errands such as booking tickets, and cannot yet show users its browser. Background checks count against the usage limits shared with other Claude activity. If an app is disconnected, Anthropic says new access stops, but information already learned remains until the user resets memory.

““Approval fatigue is a serious issue, because too many requests teach people to tap through them.””

What Preview Testing Must Establish

No independent test results are included in the source material, so Duet’s accuracy, reliability and ability to follow approval rules in real-world use remain unverified. Anthropic has described safeguards and restrictions, but the information provided does not establish how often the system makes mistakes, how well users understand each approval request or how consistently the separate classifier detects actions that do not match a user’s intent.

It is also unclear how quickly the waitlist will open up, whether access will expand beyond eligible U.S. Pro and Max subscribers, or whether the listed capabilities and limits will change during the research preview. The source material gives launch prices for competing products only as figures at launch and does not provide a complete, current price comparison. Duet’s long-term cost and its impact on users’ shared Claude usage limits may depend on the tasks they assign.

Anthropic says disconnecting an app stops future access, while previously learned information stays until memory is reset. The source material does not detail how that memory is displayed or how users can review and remove individual pieces of information. Those details matter for people connecting business records or sensitive communications.

Pilot Access and Safety Checks

Anthropic’s next step is to provide access through the waitlist and gather experience with Duet as a research preview. The source material does not specify a schedule for broader availability or a date for a full release. Users and organizations considering a trial can begin with low-stakes tasks, connect only the services needed and keep approval requirements active for actions that send, pay or delete.

Companies can use small, written pilots to record which apps an agent can access, what tasks it may perform, who reviews its outputs and how the organization will stop the trial and remove access. They should also account for the fact that background checks use shared plan limits, and that disconnecting an integration may not erase information already retained in memory.

For users, the central test will be whether Duet’s briefings and delegated work are accurate enough to save time without encouraging routine, unexamined approvals. More information about access, performance, memory controls and usage costs will be needed to judge whether the preview is ready for higher-stakes work.

Key Questions

What is Claude Duet?

Claude Duet is a separate app in which Anthropic says Claude can work as a cloud-based agent across connected services, prepare briefings and respond to instructions by text or voice.

Who can use Claude Duet?

The source material says Duet launched as a waitlisted research preview for U.S. subscribers on Claude Pro and Max plans. It does not give a timetable for broader access.

Can Duet send messages or make payments without permission?

Anthropic says Duet asks for approval before sending potentially sensitive messages, paying or deleting items. It also says trading securities, transferring money between accounts and accessing another person’s account are blocked.

Has Claude Duet been independently tested?

The source material includes no independent test results. Its descriptions of safeguards, capabilities and limitations are attributed to Anthropic.

What should a company check before trying Duet?

A company can start with a small pilot, limit connected apps and permissions, define who reviews outputs, keep approvals on for sensitive actions and plan how to end access and reset memory.
