M.I.W.

Great free option with affordable subscription for baking up all your text offline, somewhat like Diigo (which I used previously, and loved but have moved on from for various reasons). Good cross platform compatibility and also very fast and smooth, mutidevice on the go saving for my link and data hoarding self has definitely been satisfied for now.

Obsidian with its extensibility and plug-ins is an endless set of alternatives for, well, basically anything similar. As long as you can figure out how to get your workflow going. Also totally affordable and valid free use, and hooks into so so many things.
