Don't buy into all the crazy around it. It's a Markdown editor with some organisation features. If you read Reddit, people treat it like some sort of second coming, making sure EVERY NOTE THEY TAKE is linked at least one other, tagged, etc. Like somehow that makes notes better.
I was confused at first too but once I realised most of these people are insane and it's a note taking app, it's very easy simple and quick to use. I love it.
It's just ("just" in the good sense) a fancy Markdown editor with a bunch of plugins, including for most of the core features (which are just bundled-in plugins and can be turned off).
It's a pretty simple note organizer for markdown notes. That's literally it. Vaults/folders/subfolders are 1:1 representations of the folders on your physical computer.
It's WYSIWYG, so even if you don't know markdown, you can just use standard shortcuts like Ctrl-B to bold something, Ctrl-I to italicize, etc.
But it's only as valuable as the notes that it contains. If you are a fastidious note taker (for your projects, work, etc), like to ontologically tag things, and appreciate building inter-related knowledge (like wikipedia links), then you'd be hard pressed to find a better substitute even compared to other heavy hitters like Joplin and Logseq.
At its simplest, it is a UI to markdown files. When I was first looking into it, it seemed very tightly coupled with the zettelkasten method which I know nothing about. At first I thought that I was missing something but have since used it as just a markdown note app.
I will asked ChatGPT to output responses in a note form in markdown so I can copy/paste it in.
