Claude Duet works after you close the app
Anthropic introduced Claude Duet on October 21, 2026 as a research preview. It runs on a cloud computer, uses the memory, Skills and connected apps in a Claude account, and asks before sensitive actions. Access starts through a waitlist for US Pro and Max subscribers; its background work shares their plan limits.
