Use tool ↗About Quartz
Quartz is an email client built for Mac (Apple Silicon required) that sorts incoming mail into categories you define and learns over time, then drafts replies matching your writing style from a few bullet points. The distinguishing choice is that the sorting and drafting model runs locally on the Mac rather than on a vendor server, and mail is described as end-to-end encrypted with keys only the user holds. It connects to Gmail and is CASA Tier 2 certified under Google's security assessment. The product is in public beta and free; no paid plan has been announced. It was built by Datarockets, a software development studio.

Pros & cons of Quartz
Quartz is worth a look if the idea of an email client whose sorting and reply model never leaves your Mac appeals to you, and Gmail is your main account. Being Mac-only, beta-stage, and Gmail-only narrows who can use it today, and pricing after beta is still unknown.
Pros
- Sorting and reply-drafting model runs on-device rather than on a vendor server
- CASA Tier 2 certified under Google's Cloud Application Security Assessment
- Free for the full beta period with no credit card required
Cons
- Mac and Apple Silicon only, with no Windows, Linux, or mobile version
- Gmail is the only supported provider right now
- Beta status means pricing and the long-term feature set are not yet fixed
Best for
- Mac users on Gmail who want local, not cloud-side, AI sorting
- People who want AI-drafted replies without sending mail content to a server
Not for
- Windows or Linux users
- Anyone needing non-Gmail account support today
Watch out: No paid plan or price has been announced yet, so today's free access is not guaranteed to continue as-is after beta.
