Notable  

I couldn't find a note-taking app that ticked all the boxes I'm interested in: notes are written and rendered in GitHub Flavored Markdown, no WYSIWYG, no proprietary formats, I can run a search & replace across all notes, notes support attachments, the app isn't bloated, the app has a pretty interface, tags are indefinitely nestable and can import Evernote notes (because that's what I was using before).

So I built my own.

Part of this comparison is personal opinion: you may disagree on the UI front, things I consider bloat may be considered features by somebody else etc. but hopefully this comparison did a good job at illustrating the main differences.

Notes are written in GitHub Flavored Markdown, and you can also write KaTeX expressions, Mermaid diagrams and so much more, check out our full Markdown cheatsheet.

Notable also gives you a very powerful Markdown editor, it's the same one VS Code uses in fact, so features like multi-cursors, a minimap and best-in-class syntax highlighting are built-in.

Notes and attachments are simply stored on your disk, this is extremely portable and powerful: you could edit your notes with your favorite editor, have them synchronized via Dropbox, run Git on them, run a regex-based search and replace on them etc.

A dark theme is also available. In the future support for custom themes will be added as well.

If you'd like to change a color or hide a button you are also free to do that via the Devtools.

Zen mode provides a minimalistic editing and reading experience, hiding everything that's not necessary.

Notable is also keyboard friendly, has a quick open window, and we'll soon add a command palette too, so you won't have to click any buttons if you don't want to.

A multi-note editor is available for quickly running an action, like favoriting, pinning, deleting, tagging etc., on multiple notes at once.

If you need to run a more complex action on your notes remember that they are just file stored on your disk so you can do whatever you want with them.

A split-editor is available for quickly checking out how your note will be rendered while you're editing it.

A lot more features are implemented, some of the most important ones are listed here.
