Claude Duet is an AI-powered personal productivity and autonomous agent platform designed to help individuals manage information, coordinate activities, and delegate complex work.

Its proactive assistance capabilities include daily briefings that summarize important emails, calendar commitments, business developments, and outstanding decisions. Users can assign tasks through natural language text or voice messages, allowing the assistant to research information, prepare documents, schedule meetings, and manage administrative processes. Claude Duet can create spreadsheets, presentations, dashboards, reports, and other business deliverables using information from connected applications. The platform supports more than 6,000 connectors and plugins, including Gmail, Google Calendar, Slack, Salesforce, HubSpot, Shopify, and Microsoft 365. Persistent memory and integration with existing Claude skills enable the assistant to maintain contextual information across conversations and recurring workflows.
