What people are saying

Loved and trusted by many

Octarine looks FRESH! I've tried a lot of note taking apps. Got a good feeling about this one 🔥

These are my absolute favorite lifetime/one-time purchases that I use every single day: Octarine — Lightning-fast, private Markdown notes (local-first, no cloud nonsense). It's like a super-light Obsidian but way snappier and simpler.

Just downloaded the free version - the first PKM that I am already blown away by! Cannot wait for all of the features in the roadmap!

Octarine is fantastic for my needs. It's fully weaned me off Capacities as a notes app, and off iA Writer and Google Docs as my writing defaults, as well as comfortably bringing me into the world of Markdown. You're doing good with Octarine. Stay the course.

Stumbled into Octarine today. Excellent first impression! I'm an outliner, not a markdown guy, but appreciate the aesthetics and the app so far! Nice work!

Who knows, maybe some day its called OFM (octarine flavoured markdown). Thank you for continously improving octarine!

Refreshing take on a notes app, i was surprised how light weight it is. Does the job well without the need for plugins which i find useful.

For anyone considering trying Octarine… I don't regret spending the $50 in the slightest. Really… $60 is a total deal too.

IMO, octarine and zettlr offer a better experience on a mac. Obsidian is slow and bloated. Octarine especially is much snappier.
