Ditched Notion long time ago. Obsidian is better and self-souvereign. And it's just a GUI, you can keep the underlying data on the file system. https://obsidian.md/ nostr:note14029nsf89jz49kdrl2cg5dzz9dws0whjg6fscc4y9cz9eqek29yq85gl9k
I use Logseq personally as it's FOSS- it works well for me but others may want to wait until their internal rewrite is done (will probably take ~1 year at the current rate)
I use Joplin on desktop and phone. I’ll try Obsidian. Are you saying that files are stored locally in the device? How do you sync between devices?
I don't know tbh. I don't sync sensitive stuff over the internet, I have a private cloud in my LAN. But I guess, they have some cloud service running for the reckless?
