What is Claude Duet?
Anthropic opened a research preview of Claude Duet on October 21, 2026 — a new standalone app where Claude works as a proactive agent instead of waiting for your prompt. Each morning Duet sends a short brief of the most important items across your connected apps, then checks those accounts every few hours and messages you only when something genuinely needs your attention. Hand it work by text or voice in one ongoing thread, from scheduling meetings to building dashboards, financial forecasts, prototypes, and web apps.
Duet is built around Claude Opus 5.5 and runs on its own cloud virtual machine with a browser, so your laptop or phone can stay off while it works. It carries over the memory, skills, and connected apps from your Claude account, plugs into 6,000+ connectors in the Claude Marketplace (Gmail, Slack, QuickBooks, Shopify), and can chase unpaid invoices or make business purchases via Stripe Link and Shop Pay — always asking your approval first before it sends a message, pays, signs, or deletes anything. Included with Pro and Max subscriptions at no extra cost during the preview, though background work eats into your existing plan limits.
