Claude Duet is Anthropic's answer to a question that ordinary chat cannot solve: who notices the work you forgot to ask about? Announced on October 21, 2026, Duet reads context from apps you connect, offers a morning brief, accepts delegated jobs and keeps working on a cloud computer after you leave. It is a personal agent, but one designed first for professionals and small-business owners. The distinction matters if you are deciding whether you need a work operator or help across the rest of your day. Anthropic's launch announcement describes both the proactive behavior and its intended audience.
The Job Duet Is Built For
Picture a business owner who starts the day with unread customer mail, a meeting to prepare for and an overdue invoice. Duet's proposed workflow is to identify what deserves attention, draft the first replies or briefing, and take a larger assignment—such as assembling a dashboard—through the connected tools. This is not a claim that every such task will succeed unattended. It is the scope Anthropic describes for the research preview, including email, calendar, accounting and document workflows. Its getting-started guide also explains how finished files and tasks appear for review.
That focus makes Duet different from a general-purpose chatbot. A chatbot can answer a question about your inbox when you ask. Duet is designed to check connected accounts every few hours and contact you when its judgment says something needs you. “Always on” describes the availability of its cloud environment, not continuous real-time monitoring; an urgent item can arrive between checks. Anthropic says users can influence what Duet reports and how often. Announcement
Why It Qualifies as a Personal Agent
Three product choices make the classification substantive rather than promotional. First, continuity: Duet brings over Claude memory, skills and connected apps, and conversations can continue in one main thread or separate channels with shared memory. Second, initiative: it prepares a morning brief and follows up on tasks or quiet threads. Third, execution: it has its own cloud computer and browser, and can use connected services to work after the phone or laptop is off. Those details come from Anthropic's product documentation.
Execution is deliberately bounded. Duet may read and prepare work, but Anthropic says it presents important external steps for approval before sending messages, paying, signing or deleting. Trading securities and moving money between accounts remain off-limits. A separate check assesses whether an action matches the user's intent; Anthropic's security explanation describes these as safeguards, not a guarantee that the preview cannot make mistakes.

What You Can Actually Access Today
As of October 27, 2026, Duet is a research preview, available through a waitlist to Claude Pro and Max subscribers in the United States. It runs on iOS, Android and the web, uses Opus 5.5 and shares the subscriber's ordinary Claude usage limits. Background checks count against those limits, so the cost of proactivity is not just a possible interruption but also usage capacity. Team and Enterprise access is not available yet. Anthropic help center
Duet currently lives in a separate app from the main Claude app, although it uses the same account. During the preview it adds no separate fee to eligible Pro or Max plans. Its Tasks tab shows work in progress and decisions waiting for you; larger files appear in the Make tab. You can steer a task while it runs, but only you can mark it complete. Duet can also search earlier Duet conversations and Claude chats outside projects when the account's chat-reference setting is on. Launch announcement, getting-started guide
Anthropic advertises access to more than 6,000 connectors and plugins in its marketplace. That is an ecosystem total, not a promise that every integration or action works in Duet today. The help center notes limits on some connectors and says Microsoft 365 is not yet available. For a site without a connector, Duet may use its cloud browser, but you currently cannot watch or take over that browser. It cannot see all files on your local computer, call people or send them text messages. Official product page, preview limitations
The Trust Test Is Bigger Than an Approval Button
Duet may encounter customer messages, invoices and documents that were never written for an AI agent. Anthropic says credentials stay outside the model's reach, sensitive outgoing content receives a separate check, and users can review tasks and disconnect apps. Those are meaningful architectural controls, yet the company also acknowledges that its safeguards may occasionally miss or misclassify information. Disconnecting an app stops future access but does not automatically erase context Duet already learned; memory needs separate management. Anthropic's safety and privacy account
Approval does not mean Duet cannot make a purchase: Anthropic says it supports user-approved purchases through Link or Shop Pay, using a one-time card limited to that purchase. That is different from the banking transfers and securities trades it prohibits. It is also a reason to inspect the item, seller and amount before approving. Partner integration details
If you get access, begin with a task whose output you can verify, such as a meeting brief or draft reply. Check what Duet used as evidence, whether its priority judgment matches yours, and which next step would cross an approval boundary. That is a practical way to evaluate a preview without assuming that a polished morning brief proves dependable autonomy.
Claude Duet or Today?
Duet and Today belong in the same personal-agent conversation, but they start from different problems. Duet is strongest on the public evidence for a professional user whose work already lives in Claude and connected business apps. It can inherit that context immediately and hand back files or completed steps. Today is organized around continuity across personal context, plans and everyday responsibilities; what Today is explains that product direction. This is a comparison of product focus, not a benchmark or a claim that one agent is universally more capable.
Choose Duet's preview if you have a US Pro or Max account, want Claude to monitor work threads and are comfortable reviewing its proposed actions. Look beyond Duet if your main need is a broader personal context across day-to-day life, or if you need an available product outside its current preview. Our personal agent versus work agent guide explains why those needs overlap without becoming identical.
Bottom Line
Claude Duet is a real entry in the Personal Agent category, not merely a renamed chat window. Its combination of inherited context, initiative and cloud execution is unusually coherent; its first operating territory is work. The open question is whether its judgment, usage budget and approval experience will hold up beyond a limited research preview. Judge it by the work it finishes and by how clearly you can inspect and correct what it decides needs you.
