+1 for Syncthing, been using it to sync a tablet, a phone and a pc without much problem. Obsidian usually makes a separate note when there is a synch issue, so at least you don’t need to worry about losing your data.

I’m not too well-versed on the subject but, isn’t user interactions with LLM’s also train them further? They make it sound like the product has already been matured and they’re letting people use it for free.
