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.

I would say "open source markdown knowledge-base similar to Obsidian" but I'm not a marketing guy
