It's really too bad. I looked at Notion pretty extensively not long after it launched and it seemed really good compared to tools like OneNote. I wasn't at a place where I could transition to it at the time but remembered it. Several years later when I was looking for new tooling, I looked at it again and was puzzled that it seemed kinda slow and convoluted.

It's unfortunate that it's an online service. At least with tools like OneNote, now that it's been screwed up with cloud, AI, etc we can still go back to the old perpetual license, local-first versions which are still great.
