Anthropic launched Claude Duet on October 21 as a waitlisted research preview that lets Claude work on a cloud computer between user prompts. The separate app is available to U.S. Pro and Max subscribers by waitlist, placing Anthropic in a growing contest to build AI agents that monitor connected services and return with completed work or requests for approval.

Anthropic describes Duet as an agent for professionals and small-business owners. It can send a morning brief, receive tasks by text or voice in an ongoing thread, and use a virtual machine with its own browser while a user’s phone or computer is off. Anthropic says Duet carries over the user’s Claude memory, skills and connected apps, and can draw on more than 6,000 Marketplace connectors and plugins. Examples include checking invoices, working with payroll or contracts, and updating a storefront.

The company says Duet can read, draft and prepare work on its own, but must show users the action and wait for approval before sending potentially sensitive messages, making payments or deleting items. Anthropic says trading securities, moving money between accounts and accessing another person’s account are blocked even with user approval. For purchases, the company describes a Stripe Link one-time card limited to a merchant and amount. These are Anthropic’s product and safety claims; the supplied source reports no independent testing.

Duet also has operational limits, according to Anthropic. It checks connected accounts every few hours rather than continuously, and background activity counts toward the user’s Claude usage limits. The early version may misread conversations or urgency, is weaker at personal errands such as booking tickets, and does not yet let users view its browser. Disconnecting an app stops future access, but information already learned remains in memory until that memory is reset.

The Race Moves Beyond Chat

Duet’s launch is part of a shift from assistants that respond only when opened to agents that keep working in the background. The source lists Grok Bot, Meta’s Muse, OpenAI’s Dots and Google’s Gemini Agent as recent entries in the same broad category. If these products can reliably monitor services and complete routine tasks, they could change how users handle administrative work—and how companies grant software access to AI systems.

The source also points to a developing business question: who controls the routing layer between users and models. It reports that Grok Bot may route work to models from other companies, including Claude Opus 5.5, while customers cannot select a model through a public-facing picker. That account suggests the interface, connected data and task routing may matter as much as the underlying model. The arrangements and customer controls described in the source have not been independently verified here.

For organizations, the immediate issue is less about replacing staff than about permissions, oversight and measurable performance. An agent connected to email, payroll or contracts can prepare useful work, but errors or excessive access could carry real costs. A limited pilot with read-mostly permissions and explicit approval for consequential actions is a practical way to test value without treating the preview as a finished system.

A Crowded Agent Launch Calendar

The supplied source places Duet after a series of rival launches: SpaceXAI opened a 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 followed on October 21. The source characterizes these products as sharing a cloud-based approach in which an assistant can retain context, act between prompts and report back.

Anthropic’s safety post, published October 23, provides more detail on Duet’s controls. The company says a separate check, based on the auto-mode classifier used by Claude Code, evaluates whether a proposed action matches the user’s intent. It also says Duet does not see passwords, browser cookies or sign-in tokens, and that a classifier blocks sharing credentials and certain sensitive identifiers. Those protections are company statements, not results of an outside security review in the supplied material.

The source names Claude Opus 5.5 as Duet’s underlying model and says the preview is restricted by geography, subscription tier and waitlist. It gives no independent benchmark results or detailed evidence about how Duet performs across the listed connectors. Comparisons with rival products should therefore be treated as descriptions of launch-stage offerings, not a verified ranking.

“For professionals and small business owners with more on their plates than they can track.”

Preview Limits and Open Questions

Independent evidence is not yet provided for Duet’s reliability, safety controls, connector behavior or claimed privacy boundaries. The source does not report a third-party test, incident record or detailed evaluation of how often the agent misreads instructions. Anthropic itself says the early version can misjudge urgency and that approval prompts may encourage users to approve actions without close review.

It is also unclear how the waitlist will expand, when Duet might leave research preview, or whether it will become available outside the United States and beyond Pro and Max subscribers. The source does not establish how many tasks Duet can complete successfully, how much background work typical users can do within their plans, or whether information retained in memory can be selectively removed beyond resetting that memory. The claims about rival agents’ model-routing policies are attributed to the cited sources and are not independently confirmed here.

Watch for Testing and Wider Access

The next developments to watch are waitlist access, product updates and independent testing. Anthropic has not provided a public date for general availability in the supplied source. Users and businesses considering the preview should check its current terms, connect only necessary services, begin with low-risk tasks and keep approval requirements on for actions that send, pay or delete.

Companies evaluating Duet should define a small pilot in writing, use read-mostly permissions where possible, measure whether the agent saves time or reduces errors, and set an exit plan for removing access and resetting retained memory. As rival offerings develop, the practical comparison will depend not only on model quality but also on access controls, monitoring, costs and the ability to choose where tasks are processed.

Key Questions

What is Claude Duet?

Claude Duet is Anthropic’s background AI agent, offered as a separate app and through claude.ai. Anthropic says it can work on a cloud computer, handle tasks from text or voice, and report back when it needs a user.

Who can use Claude Duet?

The supplied source says the research preview is limited to U.S. Pro and Max subscribers by waitlist. It does not give a date for broader access.

Can Duet send messages or move money without approval?

Anthropic says Duet must obtain approval before sending potentially sensitive messages, paying or deleting items. The company says trading securities and moving money between accounts are blocked, even if a user approves.
