Claude Duet turns the agent proactive: a morning brief, and your approval before it acts
Anthropic opened a research preview of Claude Duet, a proactive agent app built around Claude Opus 5.5. It carries over memory, skills and connected apps from a Claude account, sends a morning brief across those apps, and keeps working on tasks in a background virtual machine. Before sending a message, making a payment, signing a document or deleting anything, it shows the action and waits for approval; the preview starts with US Pro and Max users via a waitlist.
