Anthropic opened a research preview of Claude Duet for professionals and small business owners. Instead of waiting for you to ask, it watches the apps you connect, sends you a morning brief, and messages you only when something needs your attention. It also keeps working after you close the app, on things like scheduling meetings, building dashboards and creating financial forecasts. It asks before it sends a message, makes a payment, signs something or deletes anything. It's US-only for Claude Pro and Max subscribers through a waitlist, at no extra cost, though its background work counts toward your usage limits. Anthropic says it can misread a thread or misjudge what's urgent. It's a real way to hand off routine admin, as long as you check its work.
