Anthropic’s Claude Duet wants to be the coworker who never logs off

The proactive AI agent runs on Claude Opus 5.5, plugs into over 6,000 connectors, and asks permission before it touches your money Anthropic has released an AI agent that doesn’t wait to be asked. Claude Duet, launched on October 21, 2026, watches your connected apps, flags what matters, and starts working on tasks before you open a chat window. It is aimed at professionals and small business owners. That is the crowd most likely to drown in inboxes, invoices and payroll deadlines, and least likely to have an assistant to fix it. Duet runs on Claude Opus 5.5, Anthropic’s model. It also runs on its own cloud virtual machine rather than borrowing your laptop. The agent connects to more than 6,000 connectors and plugins through the Claude Marketplace.
