ZetaNotes

ZetaNotes provides AI-powered writing assistance on your Mac with all processing done locally, ensuring no data leaves your device. It utilizes open-source models like Llama 3.2 and Qwen 2.5, optimized for Apple Silicon, and offers features such as AI autocomplete, semantic search, summarization, translation in over 12 languages, grammar correction, rephrasing, title generation, and a conversational assistant. Unlike Apple Notes, ZetaNotes operates entirely offline, requiring no internet connection, and maintains zero tracking or data collection. It offers a free tier and a Pro version at $0.99/month or $19.99 lifetime, available on the Mac App Store. Built with llama.cpp, Metal GPU acceleration, and SwiftUI, ZetaNotes is privacy-first by design.
