I would like to use my laptop for note taking in class, and use an android based e-ink tablet for handwriting and diagrams. What are your recommendations for delivering the tablet’s notes to the vault? Obsidian on the tablet with first party sync looks like a possibility. What about another app that can use SyncThing or similar that the laptop vault can turn pull?
I use git to synchronise and versionise my notes across my desktop pc and laptop. If I need access to the notes away from those two I simply access my git repository I self-hosted via gitea. Sure it has not the linking features of obsidian, but I still can read and edit the markdown files :)
My use case by the way is world building for a literature project and running Pathfinder Role-playing games.
