Writing without friction
A fast, lightweight tool for writing and planning — in Markdown that stays yours.New: Multiple contexts for assistants

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
Great, lightweight note and activity tracking app. I use it daily to keep track of my todo list (which I can important incomplete tasks from prior days) and as a PKM. Very snappy, too.
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.
IMO, octarine and zettlr offer a better experience on a mac. Obsidian is slow and bloated. Octarine especially is much snappier.
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!
Been using Octarine as my daily driver for the past few days and I'm impressed. Seriously considering jumping from Noteplan.
Guys, just use Octarine — it's that good!
Been an early adopter of Octarine and have used it daily ever since. Octarine is a delight to use! Lightweight, beautiful, highly performant!
Hey, i came here to say this implementation of an obsidian type note management app is CRAZY GOOD. Damn.
Who knows, maybe some day its called OFM (octarine flavoured markdown). Thank you for continously improving octarine!
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.
I just want to say, amazing project. I love Octarine, thanks for making it.
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.
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!
+1 to Octarine. Visually more appealing (IMO) than Obsidian. "Just works" out of the box.
Had Octarine on my radar for a while. Spent an afternoon on the landing page, changelog, and docs... everything just clicked. Eight releases in February, bug responses, random-wip showing what's cooking... that's what made me pull the trigger.
Notes are stored as markdown files on device. Always yours.
