Ligature

Ligature is a free writing and notes app for Mac that works offline without an account. Capture ideas, organize research, and develop longer drafts in a calm editor with folders, labels, backlinks, daily notes, and passage annotations. Your library stays on your computer. AI is optional: bring your own provider or local model, or leave it off. Add paid, end-to-end encrypted Sync when you want your library on more devices. An iOS beta is available by request.
