Claude Duet Reaches Out First: Anthropic's Proactive Agent Joins the Always-On Race
Anthropic unveiled Claude Duet on Wednesday, a standalone agent app that does not wait to be asked. Announced on October 21 and opening as a waitlisted research preview for United States subscribers on the Pro and Max plans, Duet monitors the apps you have connected, sends a briefing each morning, checks back every few hours, and alerts you when something needs your attention. It is built around Anthropic's Opus 5.5 model, runs on iOS, Android and claude.ai, and works in one ongoing thread that reuses the memory, skills and connectors from your Claude account.
