Overview
Quartz is an AI-native email application designed to assist users in managing their inbox efficiently. It features importance-based auto-categorization of emails, learned by the tool over time based on individual user preferences.
Quartz allows critical emails more visibility while making routine items easily scannable and minimizing distractions by tucking away noisy emails. It employs machine learning algorithms to sort the inbox and to draft replies that mimic the user's writing style, sense of warmth, and relationship with the sender, right on the user's device.
Privacy is a key focus area for Quartz, which does not upload any data to the cloud -- all the processing happens locally on the user's Mac, iPhone, or iPad.
Furthermore, there are no servers used, ensuring that neither Quartz nor anyone else can read the user's emails. It also supports end-to-end encryption with keys held only by the user.
Quartz is currently in private beta on Mac and iOS.
