If I'd try to describe/categorize it, I'd call it a local, ?most often? single-user, scriptable and plugginable wiki-software.

I use it for taking notes, keeping a journal, TODO-list, and to bookmark/annotate stuff. Basically my own personal "knowledge base".

Technology-wise it saves notes as markdown, optionally with a yaml-style frontmatter, built on/with javascript, and exposes a bunch of APIs making it very extensible.

A strength/weakness with it is that it exposes the end-user to all this power, and does not enforce much in the way of ways of working, so you get to define for yourself how you go about using it.

I have mostly settled on workflows that works for me, but it also seems, if I am being completely honest, like there is always some little tweaking/refactoring going on.
