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.
Octarine is so much better than Obsidian. With Obsidian I have to install multiple community-maintained plugins just to get basic features like text colors and highlights, but with Octarine its built in, definitely worth upgrading to the pro license as well.
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.
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!
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.
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
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!
Notes are stored as markdown files on device. Always yours.
