Kraa can't properly compete with Notion, yet. Not on the feature-set. That being said, if you value simpler interface that still has all the core editor features, give it a try!

We are also not trying to be a Notion clone/alternative, but rather a different kind of text editor that's highly customizable, has unique features (like the writer role) and keeps strong division between writing and styling.

Appears to me more like a super clean version of hack.md!
