- Claude Duet: What Anthropic’s New Proactive AI Agent Can—and Can’t—Do
Quick answer: Claude Duet is a new AI agent from Anthropic. It is designed to help professionals and small businesses by preparing briefings, checking connected work apps and continuing assigned tasks in the background. Access to the research preview requires joining a waitlist and is limited to subscribers in the United States with Pro or Max plans. It is not yet available to everyone.
Anthropic opened the preview on October 21, 2026. People can use Duet through a separate app for iOS and Android or on claude.ai. According to Anthropic’s announcement and product FAQ, Duet runs on Claude Opus 5.5.
What is Claude Duet?
A regular chatbot waits for you to ask a question. Duet is designed to do more. It can check connected apps, point out work that needs attention and carry out tasks you give it. Anthropic says it can send you a morning report, highlight important emails or calendar events, write replies for you to review, help arrange meetings and create dashboards or business documents. The product page says Duet works with more than 6,000 connectors and plugins. Reuters reports that these include Gmail and Slack.
The goal is to let people give AI work to do that can continue even after a conversation ends, instead of asking it one question at a time. This could make everyday follow-up tasks easier. However, the AI also gets more information about your work and more chances to misunderstand what is important.
Who can use Claude Duet?
For now, people in the United States who subscribe to Claude Pro or Max must join a waitlist to get access. Team and Enterprise subscribers cannot use the preview, according to Anthropic’s availability FAQ. Duet uses the same usage limits as the subscriber’s Claude plan. Checking apps in the background and handling larger tasks also count toward those limits.
This means the launch is an early test, not a feature that every Claude customer can turn on today. Reuters and CNBC also report that the preview is limited to Pro and Max subscribers and that access is being offered through a waitlist.
What can Claude Duet do—and what are its limits?
Anthropic says Duet can keep working while a user is away. It will ask for permission before doing sensitive things, such as sending messages or making payments. The company also says its systems for handling login details and safety are designed to keep passwords and sign-in tokens away from the AI agent itself. These are Anthropic’s descriptions of its safety measures. They do not independently prove that connecting your accounts is risk-free.
Anthropic warns that Duet may misunderstand a conversation, get the level of urgency wrong or miss something that appears between its checks. Reuters reports that Anthropic believes Duet is less useful for some personal tasks, such as booking tickets. A helpful briefing does not mean the AI has checked every email in your inbox. You should also review any action it drafts before approving it.
If you want to test an AI agent that works on its own, consider which apps it can access, what it can do without your permission, how much background activity uses up your plan’s allowance and how you can check or stop its work. Start by connecting only the apps you need, review the permissions you give it and require your approval for important actions.
Why Claude Duet matters in the race to build AI agents
Anthropic is entering a fast-changing market for AI agents that can work across different apps instead of only answering questions. Reuters and CNBC compare Duet with OpenAI’s Dots and Meta’s Muse, although the products serve different users and offer different features. Duet focuses on tasks for workplaces and small businesses. It does not promise to handle every personal errand.
The main test will be whether people trust Duet to make good decisions about work they ask it to do regularly. For now, Claude Duet is an early preview that requires joining a waitlist. It offers useful ideas and has safety measures described by Anthropic, but it also has known limits. Treat its suggestions as a starting point, check important details and review its actions before they affect customers, coworkers or money.
