I mostly use Google Keep, which works pretty well. Though the "clippings" feature saving Web articles is pretty cool and doesn't have much of an analogue with that product.
Google keep us awesome! Very underrated. I use logseq most of the time but keep when I'm on mobile and I'll sync them later. There are scripts to hello transfer but doing it manually is pretty easy.
But on it's own keep gives me everything I need, except for the local markdown file database.
