A Markdown notebook for macOS.
Your notes. Your files. Your machine.
Every note is a plain .md file in a folder on your Mac.
No database. No proprietary format. Open them in any editor, grep them from the terminal, back them up however you want.
You could delete mdnb tomorrow and your notes would still be right where you left them.
Standard Markdown. Nothing proprietary to learn.
[[wikilinks]]Full-text search across every note, in milliseconds. Start typing and results appear before you finish the word.
Backlinks show every note that references the current one. See the shape of your thinking at a glance.
Free forever. Your notes stay yours, no matter what.
A native macOS app for writing and organizing Markdown notes. Every note is a plain .md file on your disk.
Obsidian is an Electron app with hundreds of plugins. mdnb is a native Mac app with a focused feature set. That means faster launches, an interface that feels like it belongs on your Mac, and a command palette for quick navigation. If you want a plugin ecosystem, Obsidian is great. If you want a fast, clean writing tool that gets out of your way, that's mdnb.
Standard Markdown (.md) files. Every note is a regular file in a regular folder. Open them in VS Code, vim, or any text editor.
mdnb works with any folder on your machine. Point it at an iCloud Drive, Dropbox, or git-synced directory and it just works.
macOS only. Because your notes are plain Markdown files, you can read and edit them on any platform with any text editor.
Free. Your notes are plain files on disk, so they're yours whether you keep using mdnb or not.
