Score: 4.8/10 (Innovation: 5, Technical: 6, Documentation: 3, Utility: 5)

Mocca is a privacy-focused Mac email client that uses a local AI model to classify and manage emails (e.g., sorting receipts, job postings, and trashing promotions) entirely offline. Its unique selling point is running AI inference on-device, ensuring emails never leave the computer, which addresses growing privacy concerns around cloud-based AI. The project is interesting but early-stage, with minimal documentation and no open-source license or star activity yet.

Target audience: backend devs, privacy-conscious users
