Octarine vs Obsidian

Same markdown files, with the core features built in

Octarine and Obsidian both keep your notes as plain markdown files in a folder on your computer. The difference is how much you put together yourself.

Obsidian is a platform you shape with plugins. Its core covers linking, a graph, and properties, and thousands of community plugins and themes add the rest. If you enjoy building your own setup, or depend on a particular plugin, that's hard to beat. It also has apps for iOS and Android in both app stores.

Octarine ships the things most people reach for plugins to get: daily notes, templates, Views, Git sync, themes, and AI that searches and follows links across your workspace, all built to work together. The editor is WYSIWYG, so formatting doesn't shift as you type. Both apps read the same files, so you can open a copy of your vault in Octarine and go back if it isn't for you.
