What people are saying

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.
