It doesn’t sound like Evernote is going away, though it’s laid off its entire U.S. (and Chile) staff in favor of running the operation out of Italy. I’ve always had the best of intentions when it comes to Evernote, but I could never get in the habit of using it as my “external brain.” What use I did make of it was productive, it was a great way to keep notes and links organized by novel or story.
I’m going to give OneNote a try, mostly because I recently bought a lifetime license to Microsoft 365. I’m planning on making more use of my Rocketbook notebooks, which support saving to OneNote. The best of intentions.
