Anthropic's research preview of Claude Duet, an app where Claude works as a proactive agent, starts by waitlist with US Pro and Max subscribers.
- Anthropic describes Claude Duet as a research preview app where Claude works as a proactive agent, with a waitlist starting with US Pro and Max subscribers.
- Duet runs on a virtual machine with its own browser, so the user's laptop or phone does not need to be on, and it checks connected accounts every few hours.
- In the preview, Duet is included in Pro and Max plans and shares Claude's usage limits. It waits for approval before sending messages, making payments, signing documents or deleting anything.
Duet is a research preview behind a waitlist, so most readers cannot try it yet. Anthropic says it designed the app around Claude Opus 5.5 and that it works from a virtual machine, so it can act on connected accounts while your devices are off. That puts the approval step in focus: Anthropic says Duet shows what it is about to do before sending messages, making payments, signing documents or deleting anything, and it lists misreading a thread or misjudging what is urgent as known limits. Plan inclusion and usage limits are described for the research preview only. If you join the waitlist, try it first on low-stakes accounts, and ask Anthropic what the terms will be once the preview ends. Read on →
