Available on iOS, Android and claude.ai, Duet sends a morning brief, monitors connected apps and messages the user only when something needs attention. It carries out tasks while the user is away, using a virtual machine, and checks before acting. Anthropic says a new classifier is designed to reject requests to share the most sensitive information, such as credit card numbers. Access is through a waitlist.
