AI email client built for focus. Runs locally on your Mac
Quartz turns Gmail into a focused inbox. It sorts every message by importance, and learns what matters to you over time. When you reply, it drafts in your own voice. And the AI runs entirely on your own Mac, so your mail stays end-to-end encrypted and never shared with AI providers.
We built Quartz because our own inboxes had become impossible to keep up with.
AI made it easier than ever to send emails at scale. We think AI should also help people defend their inboxes from that noise.
Quartz is an AI-native email app that protects your focus and helps you get through email faster. It learns your style and preferences over time, so it gets better the more you use it.
And because email is private, Quartz runs entirely on your device. Your emails are not sent to AI providers.
Excited to share it with you today. We’re currently in public beta and free to use.
We’d love to hear what you think!

Who hunted Quartz?
Quartz was hunted by Pavel Demeshchik. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
