I used to use Zim and it was splendid. Then I went down a few rabbit holes and explored a more GUI-less approach, but in my case nothing ever approached the level of Zim. It is more on me, than on tools. Now, when I'm doing a job that finally doesn't cause me a burn out I am slowly going back to Zim and I like it.
Full agreement. I use Zim Desktop Wiki for years now and still use it daily, but it has become harder. I also write on mobile and the experience is lacking. I don't mind syncing with Syncthing, but there is no good editor. Markor is able to open Zim files (which are just text files with markup) but it is just not cutting it.
Maybe I need to wait until the itch becomes too large to ignore and start my own little side project :/
I've had great success with using Joplin for this, with Syncthing as a sync backend. Works well across OSes; I use it on Linux, macOS, Windows and Android.
With the added expense of increased complexity cf something like Zim, I find that MediaWiki runs pretty well in a Docker container and is quite easy to edit on mobile.
