Overview
- Anthropic launched Claude Duet as a research preview on October 21, 2026, and the agent is currently available by waitlist only to US Pro, Max, and Ultra subscribers.
- Duet runs on the Claude Opus 5.5 model inside its own cloud virtual machine so it can monitor connected apps and continue working when a user’s device is off.
- The agent links to more than 6,000 connectors through the Claude Marketplace and can pull from email, calendar, Google Docs, and Slack to create swipeable task cards and draft messages.
- Duet can prepare payroll and initiate payments using Stripe Link and Shop Pay but requires user approval for sensitive transactions and blocks certain high‑risk actions by default.
- Hands-on testing shows Duet is useful for daily briefings and routine automation but can be intrusive, misjudge urgency or nuance, and Anthropic says it is iterating on judgment, permissioning, and controls before a broader rollout.
