Yuyutsu

A private, on-device Gmail assistant that drafts replies in your writing style.

Yuyutsu helps you reply to Gmail emails in your own writing style without connecting your inbox to an external AI service. Open an email, click Yuyutsu, and generate a personalized reply beside Gmail. Copy the result when it is ready or regenerate another version. You always review the response and send it yourself. Before accessing Gmail content, Yuyutsu shows a clear first-run notice and waits for your agreement. It reads only the subject, sender, and opened email text needed for the reply feature.
