but Zim is great for noting
"bits and bytes" since Omnivore is shutting down.
Obsidian is the most popular Windows, Android, Mac & iPhone alternative to Zim.
Obsidian is the most popular free alternative to Zim.

Zim is more lightweight. Obsidian has better UI and more community plugins.
Zim saves to .txt and has built in folder notes. Obsidian users rely on too many community plugins, making Obsidian inherently less secure.
