Introduction:Manzoni is a privacy-first macOS word processor and system-wide writing assistant that runs open-source language models locally on the user’s Mac.
Manzoni combines a distraction-free editor with a writing assistant that can be invoked by hotkey inside other Mac applications. It can draft, summarize, translate, change tone, find synonyms, and improve selected text while storing documents and processing writing on the local device.
Local processing reduces cloud exposure but does not remove the need for care. Model quality and speed depend on Mac hardware and the chosen model, local documents still require backups and device security, and generated claims or edits should be reviewed before professional or academic use.
