Claude Duet

Claude Duet is a proactive agent powered by Opus 5.5, available in Pro and Max plans in the US as a research preview. It takes on tasks, works autonomously, and waits for user approval when necessary. Built for judgment, it briefs users daily, drafts next steps, and can set up meetings or build dashboards. It operates securely in a user's cloud computer, ensuring privacy, and integrates with existing Claude account memory, skills, and apps.
