Anthropic opened a research-preview waitlist for Claude Duet on October 21, starting with Pro and Max subscribers in the United States. The new app can prepare morning briefs, periodically check connected work apps and continue assigned tasks while a user's own devices are off. Team and Enterprise plans are not included yet.
Duet uses Opus 5.5 and carries over the user's Claude memory, Skills and connected apps. It is offered through standalone iOS and Android apps and on claude.ai. Joining the waitlist does not grant immediate access; Anthropic says it will email people when Duet is ready for them.
Background Work Shares the Plan's Limits
The research preview is included in Pro and Max rather than sold as a separate subscription. It shares those plans' usage limits with the rest of Claude. Background checks count, and larger jobs such as building a financial model or a presentation need more model turns and background work.
Anthropic says Duet checks connected accounts every few hours, rather than watching them continuously. Users can adjust what they want to hear about and how often. A task can keep running on Duet's cloud virtual machine and browser without the user's laptop remaining on.
Duet can initiate a morning brief or flag a task that needs attention, then take instructions in one continuing text or voice thread. The product lists invoice reminders and meeting scheduling among its uses.
Approval Remains Part of the Workflow
Anthropic says Duet shows the planned action and waits before sending a message, making a payment, signing a document or deleting anything. Securities trading and moving money between accounts remain prohibited even with approval. Users can disconnect apps.
Anthropic says a dedicated safeguard rejects sharing card numbers and government IDs, while sending health or personal-finance information requires an explicit instruction. These are company-described protections.
The preview can misread a conversation, judge urgency poorly or miss something between checks. Anthropic also says personal errands are less developed than work tasks and users cannot yet see Duet's own browser. Signing into sites with saved 1Password logins is described as coming soon.
