Anthropic opens Claude Duet, a proactive agent app, in research preview
Overview
Anthropic has opened a research preview of Claude Duet, an app in which Claude works as a proactive agent.
Anthropic's blog post says Claude flags items needing the user's attention, completes requested tasks, keeps working when the user steps away, and checks with the user before acting on their behalf. Anthropic says the app shows the user each message, payment, signature or deletion before acting, and blocks sharing of the strictest tier of sensitive information, such as credit card numbers and government ID. The preview is included in US Pro and Max plans, runs on Claude Opus 5.5, and is available through a waitlist.
TestingCatalog, in a relayed post, says Claude Duet can buy things through Stripe's Link wallet and check out with Shopify's Shop Pay, and will later sign in to sites with logins saved in 1Password. Anthropic's blog post as reported does not list these shopping and login features.
