Quartz

The application automatically sorts incoming messages into categories such as important items, FYI updates, and noise. This approach keeps the inbox focused and scannable while collapsing less relevant content out of view. Users define importance through ongoing interaction, allowing the system to adapt over time. Privacy is maintained through fully local operation on Apple Silicon devices. Messages remain encrypted on the device with user-held keys, and no servers are involved in classification or drafting tasks. This setup prevents any external access to email content. Reply generation draws from a few provided examples to capture individual writing patterns, sender relationships, and thread context. The resulting drafts reflect the user's typical tone and phrasing rather than generic language.
