Writing, without friction.
Capture ideas quickly, organize them naturally, and build workflows around your thinking. All in a fast Markdown workspace designed to stay lightweight.
A quieter place to think, write, and work.
Octarine is built slowly, deliberately, and independently.
I believe good software should get out of the way. It's user-focused by default — designed around how people actually think, write, and work, not around metrics or funnels.
Octarine is bootstrapped. No venture capital. No growth-at-all-costs roadmap. The product answers to its users, not investors.
It's opinionated by design. I make clear choices so you don't have to spend time configuring every detail. Instead of endless options and switches, it ships with defaults that are meant to feel right and stay out of your way, so you can focus on the work rather than the tool.
Your data is yours. Always. Data isn't the moat — the experience is. It's built around interoperability, open formats, and tools that work with the rest of your system instead of locking you in.
Batteries are included. Core features aren't hidden behind plugins, extensions, or marketplaces. What you need to do real work ships with the app, thoughtfully integrated from day one.
This exists to be calm, intentional software in a noisy world — built by one person, for people who care about their tools.
Thanks for stopping by, and I hope it helps you find joy in writing, as it has for me.
Cheers,

Carefully crafted features that bring joy to your workflow.
Small Footprint. But doesn't lack a punch.
Contexts that don't collide
Separate work and personal with isolated workspaces. Each has its own settings — no shared state, no mixing.
Organization beyond folders
Find related content anywhere in your workspace with hierarchical tags. One click surfaces everything connected — in search or graph.
Building blocks, not blueprints
Insert reusable content blocks anywhere in your notes. Simple markdown files you can use once or a hundred times.
Loved and trusted by many
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!
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.

Notes are stored as markdown files on device. Always yours.
