Quartz

On-device, encrypted AI email triage for Gmail that drafts replies in your voice.

Webunknownglobal

Quartz is a focused-inbox tool for Gmail that automatically sorts every message by how much attention it deserves — Critical, Routine, FYI, Icebox, or Noise — with user-defined categories it learns over time. All AI processing runs on-device and mail stays end-to-end encrypted rather than uploaded, and when Quartz drafts a reply it writes in the user's own voice based on the thread history.
