HYPE OR FACT? · CHECKED 21 OCTOBER 2026
Claude Duet: Anthropic's proactive agent app
OUR VERDICT
Partly factOur original verdict: “Mostly fact (with hype to trim).”
THE CLAIM
“Anthropic opened 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.'”
What’s actually true
- It's a separate app for iOS, Android and the web, running on Opus 5.5, that sends a morning brief from your connected apps, checks in every few hours and keeps working on its own cloud computer. It asks before it sends, pays, signs or deletes anything, and some actions (such as trading or moving money between accounts) stay off-limits even with approval.
- The hype to trim: it's a waitlist for US Pro and Max subscribers only and not available in the UK yet; it uses your plan's usage limits; it checks every few hours rather than in real time; Microsoft 365 isn't supported yet; and Anthropic itself says it can misjudge what's urgent.
