Claude Duet

About Claude Duet

Claude Duet is a proactive AI assistant developed by Anthropic for professionals, entrepreneurs, and small business owners. Introduced on October 21, 2026, as a research preview, Claude Duet is designed to identify tasks that need attention, monitor connected applications, and complete work on behalf of users. Unlike a conventional request driven interaction, it can initiate communication when it detects information requiring the user's attention.

Built around Claude Opus 5.5, Claude Duet provides daily briefings, monitors connected accounts, and executes tasks through a combination of application integrations and browser interactions. Users can assign tasks through text or voice in an ongoing conversation. The agent determines which connected applications to use and which steps to perform. Its supported workflows include meeting scheduling, invoice management, financial forecasting, dashboard creation, and web application development.

Claude Duet operates within its own virtual machine and browser, allowing tasks to continue even when the user's computer or mobile device is switched off. It carries over memory, skills, and connected applications from the user's existing Claude account. The agent checks connected accounts periodically, delivers notifications, and requests human approval before performing specified consequential actions.

Claude Duet integrates with services available through the Claude Marketplace, including business communication, accounting, CRM, ecommerce, document management, and design applications. It includes approval controls for outgoing messages, payments, document signing, and deletion. The research preview is available through a waitlist, initially for eligible users in the United States, with access through a standalone iOS or Android application and claude.ai.
