This is exactly how I use Synchi! Same idea but I use Logseq instead of Obsidian (very similar open-source alternative, worth checking out). Works great for syncing markdown notes between computers and my phone on demand. Of course I need to remember to sync before switching devices, but I prefer this then constant running in the background.
Haven’t thought about an Obsidian/Logseq plugin but honestly that sounds like a great idea… For now it’s CLI only, but I can definitely see the value.















iOS is tricky since there’s no easy way to set up SSH access to the filesystem like you can on Android with Termux. So unfortunately not really supported at the moment. If you have a jailbroken device it might be possible, but that’s not something I’ve tested.
