Key points

  • Anthropic released Claude Duet as a research preview for Pro/Max plans in the US on October 21, 2026.
  • Duet continuously checks email and business apps, delivering a daily top‑3 summary and flagging unusual notifications.
  • Irreversible actions like sending, paying, or deleting require explicit user approval before execution.

This safety guard lets users delegate preparation work while retaining final judgment. Although Claude Duet is not yet available in Japan, the article suggests a simple three‑step process—list what you check each morning, mark what can be summarized, and define a one‑line approval rule—to emulate the approach today.

Early adopters report that the proactive AI shifts the typical 30‑minute email‑reading routine into a decision‑making window, freeing time for higher‑value tasks.
