Loved and trusted by many
A great note-taking app with a clean, clutter-free UX. It makes it really easy for me to track things, stay organized, and find what I need quickly.
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.
Octarine is my new favorite daily planner, knowledge base, and journal. Everything works intuitively right out of the box, so I can spend my time writing instead of worrying about creating some theoretical perfect setup.
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.
Great, lightweight note and activity tracking app. I use it daily to keep track of my todo list (which I can important incomplete tasks from prior days) and as a PKM. Very snappy, too.
+1 Octarine This app is so good. It is moving fast and is a 1 time purchase. Local plain text files and a great design.
Excellent application. I love that it's local and has everything integrated, without the need to install dozens of plugins just to make it work. Personalization is simple and practical: it's not complicated, and you can easily configure it without having to write CSS code directly in the app. This tool gets straight to the point—it's designed for writing notes, not for turning system management into a second job.
IMO, octarine and zettlr offer a better experience on a mac. Obsidian is slow and bloated. Octarine especially is much snappier.
Hey, i came here to say this implementation of an obsidian type note management app is CRAZY GOOD. Damn.
Been an early adopter of Octarine and have used it daily ever since. Octarine is a delight to use! Lightweight, beautiful, highly performant!
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.
Combination of simplicity and functionality is what makes it such a great tool. With Logseq and Capacities I find myself spending too much time on "the system", with apple notes I am missing key features, Octarine is the perfect middle ground that allows me to do what I need efficiently.
I found it via Reddit post that was listing Black Friday sales. Someone asked about your app. After a few hours on the free version I didn't need a sale. Amazing app and so rare to see one time purchase software these days. So kudos to you!
Awesome new experience. Loving it. Nice work! I am using the app daily as my go-to note app
+1 to Octarine. Visually more appealing (IMO) than Obsidian. "Just works" out of the box.
Notes are stored as markdown files on device. Always yours.
