Claude Duet is a proactive agent app that keeps working after you step away
Anthropic opened a research preview of Claude Duet, starting with US Pro and Max subscribers on a waitlist. Built around Claude Opus 5.5, it sends a short brief each morning on the most important items across your connected apps, messages you only when something needs your attention, and checks with you before it acts on your behalf. A new dedicated classifier rejects requests to share the strictest tier of information, such as credit card numbers and government identification.
