I have Zotero set up with some plugins that create a .bib file I create notes for in Emacs. I enjoy this setup because it allows me the convenience of saving files quickly using Zotero, but saves all the data it extracts to an open format with an auto export. If Zotero were to disappear tomorrow, I’d still have all my notes in org files and my citations in their bib file.

Don't suppose you have blogged about this? Or have recos for resources on combining Zotero with emacs? this sounds very intriguing!

Taking a guess here, but Evernote? :)

Not the person you're replying it to. I had that happen with Microsoft's OneNote. I really liked it and I had no problems parsing the XML files it made so I could pipe data into other systems but then it went 100% cloud storage.

It was a classic example of "Microsoft made something surprisingly good, made people think it was crap because they stuffed five OneNote icons on your taskbar and three up your nose, and then they wrecked it", must have come from the same mind that thought buying Activision was a good idea.

Yes, but in addition to that, it is owned by a non-profit who hasn’t made a single controversial update in 20 years, so it’s got a pretty decent track record.
