Thanks for a good observation! Indeed, I don't position it as Obsidian alternative. I don't know a better pitch for it just yet.
For me that's something about: simplicity, lazy flow of adding things, readiness to use out of the box.
To focus on what works, and not what is fancy.
The boringly simple knowledge base.
When I read “alternative” I immediately had a rant in my head about people calling things alternatives that are not.
