Joplin does yes. I just didnt really want to run separate server side software specifically for notes alone. I've never heard of Obsidian, maybe I'll take a look into them later. Do you know how they work? I'd be ok if it were syncing directly between pc and mobile somehow but In looking to avoid using a 3rd party. For now I'm using Plainpad on my server because I access it on PC and install it as a PWA on Android.
