Quartz
AI-native email app that filters noise and writes like you
Quartz is an email client for Mac and iPhone that uses on-device AI to prioritize what matters and draft replies in your own voice. It auto-categorizes messages by importance you define and learns over time, giving critical threads space while collapsing routine updates and noise. Because classification and drafting run locally on Apple Silicon and mail is end-to-end encrypted with keys you control, nothing is uploaded or shared with AI providers. Quartz works with Gmail so you can stay focused without sacrificing privacy.
