It's just reading/writing a directory of files. If you set it up to save into a synced directory, whether that be Google Drive, OneDrive, iCloud, Dropbox, whatever, you can point all your Obsidian installs on various machines to the same synced directory and it'll give you the same effect.
Is there a good way to sync between Mac OS, Windows and iOS? Seems like you can only pick 2 out of 3.
Edit: Today I learned there is iCloud for Windows, so you can point Obsidian to the iCloudDrive/Obsidian folder.
Going to give it a try.
The Windows version of iCloud causes file duplication and corruption with Obsidian, unfortunately.
