Key points from the news
- Claude Duet research preview launched for US Pro and Max users, accessed through a waitlist.
- Built on Claude Opus 5.5, the app runs on its own VM, checks apps every few hours, and uses shared usage limits.
- Supports over 6,000 Claude Marketplace connectors; requires user approval for payments, signatures, and blocks trading securities.
Claude Duet is built around Claude Opus 5.5 and runs on a dedicated virtual machine with its own browser, so it can act without the user’s device being on. It checks connected apps every few hours, counts toward plan limits, and sends brief morning summaries and alerts when tasks need attention. Users interact via typed or voice messages in a single thread.
The agent can schedule meetings, build dashboards, draft financial forecasts, prototype web apps, and integrate with over 6,000 Claude Marketplace connectors such as Gmail, Slack, QuickBooks, Stripe, Gusto, LinkedIn, Canva, and Shopify. Before any payment, document signing, or deletion, Claude Duet shows the proposed action for user approval; trading securities and moving money between accounts are blocked. Anthropic says safety is handled by a dedicated classifier, red‑team testing, and a HackerOne bug bounty. Early testers include Anthropic staff and a handful of small‑business owners.
