## Summary

Anthropic announced Claude Duet on October 21, 2026 as a research preview for its Pro/Max plans in the United States. The agent runs continuously, checks connected email and business apps every few hours, and delivers a concise morning briefing that highlights the top three items you need to act on. It builds on the Claude Opus 5.5 model and is designed to surface buried notifications such as failed payments before you open each app.

The system follows a strict “approval line”: summaries and draft replies are auto‑approved, but any action that sends, pays, purchases, or deletes requires your explicit confirmation. 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.
