Why Octarine

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,
Rajat

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.

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 🔥

discord /commonchilddev

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!

discord /sHìí

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!

reddit /Nefarious_Astronomer

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

discord /Grunge

Been an early adopter of Octarine and have used it daily ever since. Octarine is a delight to use! Lightweight, beautiful, highly performant!

email /Akshay Deshmukh

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.
