AR008 · 24 Oct 2026 · 46 s · by — AI Strategist, Practitioner & Educator · Founder, AI Center of Excellence

Claude Duet explained: Anthropic's new always-on personal assistant. It's a separate app that keeps an eye on the apps you connect (email, calendar, Slack), sends you a short brief every morning, checks in every few hours, puts information from different apps together, and asks before it sends, pays, signs or deletes anything. The catch: it uses your normal Claude limits, and it's always running.

Claude Duet is an always on personal assistant. It doesn't wait for you. It messages you first. It's a separate app. You download it and choose which apps it can see. Email, calendar, Slack. Every morning, a short brief. Right now, it checks your apps every few hours and writes only when something needs you. I expect it will soon watch them nonstop. And it's not just an email assistant. It puts your apps together. A client call right before a flight, it sees both and offers to move the call.

But the big decisions stay yours. Before it sends, pays, signs, or deletes anything, it asks. There is one catch. It uses your normal Claude limits. How much depends on the task, but it's always running. So connect only what you need. Always on is great, but only if it sees what helps you.
