The only reason I'm not already using ellipsus.com is the fact that it only works when you have an internet connection. I'm currently using Obsidian, which is far from optimal for writing stories, yet it's local first philosophy combined with relatively easy online sync is what keeps me using it.
With Obsidian, I know that even on that car ride, even on that spotty or nonexistent Wi-Fi network, I'll still be able to not only write but also read all of my writings. This is why I never used stuff like Google Docs either. Sure, it has some offline functionality, but only for the stuff you explicitly mark.
Ideally, Ellipsus would have an app or PWA which works offline and lets you take specific items or your whole library with you so that you can edit and read and edit. Then it all syncs when you get reconnected. I can see that this is a tall ask, though. This stuff is hard.
