Quartz

Important messages get the room they need. AI drafts sound like you.

Quartz is an AI‑powered email client for Gmail that runs entirely on your Mac, keeping every message private and never uploading data to external servers. Using on‑device, Apple‑Silicon‑optimized models, Quartz automatically categorizes incoming mail by importance—highlighting critical messages while collapsing FYI, Icebox, and noise. It also drafts replies that mimic your personal writing style, tone, and relationship context, ensuring responses sound like you. End‑to‑end encryption protects your data, and the service holds CASA Tier 2 certification for security. Quartz offers a clean, focused inbox experience, free for beta users, and is available for download on macOS.
