Claude Duet previews background work on a cloud computer
Claude Duet is Anthropic’s research preview of a proactive agent that checks connected apps, prepares work and continues tasks on its own cloud computer. Anthropic says it requests approval before sending messages, paying, signing or deleting. Access starts through a waitlist for US Pro and Max subscribers, and background checks consume the same plan allowance as ordinary Claude use.

Why it matters
The preview illustrates a workflow where the agent returns with work or a decision, even while the user’s devices are off.
More context
The October 21 announcement describes mobile apps and web access, inherited Claude memory and connectors, and account checks every few hours. Join the eligible preview and begin with a narrow task whose result can be reviewed before granting it broader app access.
Keep in mind
This is a vendor-described research preview, not general availability or a reliability guarantee. Anthropic says it may misread conversations, misjudge urgency or miss items between checks; Team and Enterprise plans are not included yet.
