EverNote is all about dropping random files into it (images, pdfs, etc). It's where you store your bills, your receipts, your photos of wine labels. It also has a very handy web clipper extension to save web pages (whole pages, sections, or bookmarks).
I'm sure plenty of people use it differently, but I'm also quite confident (from how I've seen others describe it) that one its primary use-cases is as a big shoebox to dump everything into. You then search for that stuff through titles, tags and OCR in photos.
I use it in a fundamentally different way from Obsidian.
Anyway... I have never used EverNote (==note taking?). And, as you have read, I am reaaaaally in Obsidian (==knowledge management?).
Can any of you elaborate of the conceptual difference between both?
Both are valid and powerful tools but the use cases are different, maybe just because the definition of "second brain" has moved since Evernote was conceptualized on the 2000s.
