I started out using [Bear Notes](https://bear.app) and when I learned of [Obsidian](https://obsidian.md), I promptly switched to it. Obsidian is a rabbit hole on its own but you can have syncing issues if you’re switching between platforms.

I’m currently investigating [AnyType](https://anytype.io) as I’ve heard really good things about it. I would self-host as a rule provided the convenience does not suffer much. There are levels to this self-sovereignty thing.
