Notenik
Free macOS notes app with structured fields plus markdown bodies.
Notenik is a free, open-source macOS app that combines structured metadata with markdown: each note carries typed fields (title, tags, dates, links, status) above a markdown body, stored together in plain text.
That structure makes it double as a lightweight database — reading lists, contact logs, blogs — while staying fully portable, and it can even publish collections as websites.
