Quartz

Quartz is an AI-native email client designed to transform how you manage your inbox. It uses artificial intelligence running directly on your Apple devices to automatically sort emails by importance, learn your communication patterns, and draft replies that sound authentically like you. The tool prioritizes messages that need your attention while collapsing less important emails out of the way, creating a focused email experience that adapts to your workflow.

What sets Quartz apart is its commitment to privacy and personalization. Unlike cloud-based AI email assistants, Quartz processes all data locally on your Mac, iPhone, or iPad using Apple Silicon. The AI learns your writing style over time, understanding your relationships with different contacts and the context of each conversation. This results in reply drafts that match your natural cadence and phrasing rather than generic AI-generated responses.

Quartz works best for professionals who handle significant email volume and value both productivity and privacy. It's particularly useful for those who want to maintain control over their communications while benefiting from AI assistance. The tool helps users quickly identify critical messages that need immediate response while automating the drafting process for routine replies, making email management more efficient without compromising security.
