Claude Duet app is Anthropic’s bet on agents

Anthropic says Duet proactively delivers its recommendations as it monitors ongoing tasks. Built on the Claude Opus 5.5 model, Duet can connect to over 6,000 connectors and plugins in the Claude Marketplace. It can also make online purchases on users’ behalf via Stripe’s ⁠Link digital wallet or Shopify’s Shop Pay.

The company said sensitive steps like payments would require user approval. However, Duet won’t trade securities or move money between accounts.

Anthropic also released a new classifier to check each message to prevent sensitive information from leaking out. It said that, by default, the agent would turn down requests asking for credit card numbers and government identification.

Claude Duet is available as an app on iOS and Android, and on the web through Claude.ai for Pro and Max customers in research preview. Users have to join a waitlist to try it.
