Anthropic has unveiled Claude Duet, a new proactive AI agent designed to work in the background and act on your behalf. Announced on Wednesday as a research preview, Duet is the company's answer to Meta Muse and OpenAI Dots, two rival agents that have already generated significant buzz in the AI space.
The tool is not widely available yet. Anthropic subscribers in the US can join a waitlist to try Claude Duet, with invitations going out in waves. The agent runs on Anthropic's Opus 5.5 model and is available through standalone iOS and Android apps, as well as on the web at claude.ai.
Claude Duet features and availability
Claude Duet is described by Anthropic as a proactive agent that comes to you with what needs your attention, completes tasks you ask of it, and keeps working even when you step away. It checks with you before acting on your behalf.
The agent generates a short daily briefing with action items from your connected apps. It can handle simple administrative tasks like scheduling meetings, as well as more complex work such as building dashboards, creating financial or sales forecasts, prototyping, and building web apps.
Claude Duet runs on its own cloud-based virtual machine, so it continues working even after you close the app. It uses the same memories, skills, and connectors as regular Claude, and can search past conversations. The agent also integrates with Stripe for unpaid invoices, and Link and Shop Pay for purchases with user approval.
