Information summaries and work in the background
Anthropic says Claude Duet is designed around Claude Opus 5.5. It summarizes important information from connected apps and performs requested tasks. A virtual machine with its own browser lets work continue even when the user's computer or phone is not running.
Approval requirements and preview conditions
The company says sending messages, payments, signatures and deletion require showing the action and waiting for user approval. Access initially requires a waitlist for US Pro and Max users. Limits are shared with other Claude use, and background checks consume them. The preview can still misread information or judge urgency incorrectly.
