Been using Octarine as my daily driver for the past few days and I'm impressed. Seriously considering jumping from Noteplan.
Oh my god it is perfect! Thank you so much!! I love how it renders the diagram under the definition instead of replacing it, perfect!! You have a user for life!
Started using Octarine a few days ago and it is such a beautiful app. Everything is just right — not too much, not too little.
Octarine looks FRESH! I've tried a lot of note taking apps. Got a good feeling about this one 🔥
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!
heyyy thx a lot of this great app! currently using it from the same dir as my obsidian notes and it works flawlessly!
I just want to say, amazing project. I love Octarine, thanks for making it.
Hey, i came here to say this implementation of an obsidian type note management app is CRAZY GOOD. Damn.
For anyone considering trying Octarine… I don't regret spending the $50 in the slightest. Really… $60 is a total deal too.
Awesome new experience. Loving it. Nice work! I am using the app daily as my go-to note app
Who knows, maybe some day its called OFM (octarine flavoured markdown). Thank you for continously improving octarine!
After testing upwards of 75+ apps, I settled on Octarine. From my personal needs matrix, Octarine was the only app that checked all my boxes aside from missing iOS apps. I love this app!

I really like Octarine's purpose of having all of its features built-in. A lot of Octarine is much like how I've set up Obsidian-- except I didn't scramble for extensions that depend on each other to work
Been an early adopter of Octarine and have used it daily ever since. Octarine is a delight to use! Lightweight, beautiful, highly performant!
Great self contained without plugins alternative to Obsidian
I rely on the Octarine app every day. I use it to jot down my daily plans, sprint plans, and project checklists before I start working. Having a tool that's so easy and intuitive to use really reduces a lot of friction in my workflow. This is truly the next generation of note-taking for developers.
