Catch up: @AnthropicAI's Claude Duet is a new app where Claude acts as a proactive agent, flagging what needs you and checking before it acts. Built on Opus 5.5, it's a waitlist research preview for US Pro and Max users.

Anthropic announced Claude Duet on October 21. Instead of waiting for prompts, Claude looks for what needs your attention and checks with you before it acts. It runs on Opus 5.5 and carries over your existing Claude memory, skills and connected apps.

On safety, Anthropic says Claude never directly sees your passwords, and a classifier screens for sensitive information. Access is through a waitlist for Pro and Max subscribers in the US. Follow @BroadwakeAI for more.

We’re opening a research preview of Claude Duet, a new app where Claude works as a proactive agent. It comes to you with what needs your attention, completes tasks you ask of it, keeps working when you step away, and checks with you before it acts on your behalf.
