Heh, the author admitted that he got tired of what I'll call "curating metadata" in Obsidian, so wrote an app that handled more of it automatically.
My take: you probably don't need so much metadata!
I've spent an unreasonable amount of time trying to figure out the perfect knowledge management app for me and honestly, I'm pretty sure I will get a lot of mileage out of something you just throw pages into, search to find it again, and ask AI to summarize/consolidate when you need it again.
