Do Pages, Numbers and Keynote for Mac/iOS offer real-time collaboration on shared documents like Pages, Numbers and Keynote for iCloud do? In Pages and Numbers (I guess Keynote too) for iCloud if you share a document and then send the link to other people you get real-time collaboration between the contributors as they edit the document and you can see the edits taking place live.

Does this work on Pages and Numbers for Mac/iOS?
Yes, you can use Real Time Colaboration on a computer with at least
iOS 10 and macOS Sierra.
