Claude Duet

Claude Duet is Anthropic's proactive personal agent app, in research preview. You message it like an assistant: it sends a morning brief from your connected apps, keeps watch on your inbox, calendar and follow-ups through the day, and only pings you when something needs you. You can also hand it tasks, from scheduling meetings to building dashboards or simple web apps, and it keeps working when you step away but checks with you before acting on your behalf. It runs on iOS, Android and claude.ai, starting with a waitlist for US Pro and Max subscribers on their existing plan limits.
