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.

Could you build this?
Partial Building an email client UI is straightforward, but integrating local LLM inference on Apple Silicon (CoreML/Metal/MLX) with offline fine-tuning/few-shot ranking and passing strict Google CASA Tier 2 security audits requires non-trivial native development.
What it would actually take: The app needs a native macOS wrapper (Swift/SwiftUI) running local quantized models via llama.cpp, MLC-LLM, or MLX to categorize and draft replies without server dependencies. Gmail sync requires robust IMAP/OAuth handling with strict sandbox controls and security hardening to pass third-party CASA Tier 2 security certification.
