What people are saying

Loved and trusted by many

Octarine has brought joy back to my note-taking process. As someone who has used his fair share of notetaking tools, from Roam, Obsidian, Logseq, Mem.ai, and Apple Notes, this app brings some of the best features from each and combines it with an AI-powered toolkit to make writing notes a delightful experience.

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.

+1 to Octarine. Visually more appealing (IMO) than Obsidian. "Just works" out of the box.

SaishDawgreddit

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

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.

rajniuneed

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!

Stefdiscord

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.

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 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.
