Anthropic opened a research preview of Claude Duet, a proactive agent that surfaces work needing attention and carries out tasks in the background, for US Pro and Max subscribers on a waitlist.
- Built around Claude Opus 5.5, Duet is aimed at professionals and small business owners managing crowded workloads, sending a morning brief from connected apps and checking those accounts every few hours.
- It runs as a standalone app on iOS, Android and the Claude website, separate from the main Claude app during the preview, and is included in those plans under their existing usage limits.
- Duet carries over memory, skills and connected apps from existing Claude accounts and can use more than 6,000 connectors and plugins in the Claude Marketplace, with announced use cases spanning Gmail, Slack, QuickBooks, Stripe and Shopify.
- Anthropic says Duet can read, draft and prepare work independently but must show the proposed action and wait before sending a message, making a payment, signing a document or deleting anything, and securities trading and transfers between accounts remain prohibited.
- The preview has limits: Duet may misread threads or rank urgency poorly, personal errands are less developed, users cannot yet view its browser, and background checks consume plan limits.
