I replaced Google Docs with the free, open-source collaborative editor Outline, and I think I'll stick with it
Outline is a note-taking free app, but it can be a more reliable text editor than Google Docs, and here's why.

But recently, I tried Outline, a free and open-source knowledge base and collaborative editor that has features rivaling those of Google Docs. Here’s why I’m strongly thinking of switching to Outline.
