Dropbox Paper

Dropbox Paper is your team’s collaborative workspace. It’s a workspace that brings creation and coordination together. Write and edit, brainstorm, review designs, manage tasks, or run meetings.

Launched only in January 2017, Paper is another cloud document collaboration tool. Being younger than Google Docs, its UI is more modern and has no distractions - a very important need for a writer. Further, has made sharing of all kinds of content, not limited to only text, a lot more easy.
