Quartz
AI email client built for focus. Runs locally on your Mac
In plain words
Quartz is an AI email client for Mac that transforms Gmail into a focused inbox by sorting messages by importance and learning user preferences over time. It drafts replies in the user's own voice and runs entirely locally on the Mac, keeping emails end-to-end encrypted without sharing data with external AI providers. The tool is designed for people seeking a more streamlined email experience with personalized assistance.

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.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15).

The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
