GDocs is definitely a full office suite replacement. It could capture the same use case of Paper, but it tends to be too heavy and focuses too much on formatting. Quip is a definite competitor. It tends to do better for knowledge base style collaborations, whereas Paper is better for ephemeral collaboration. But it is lightweight and focused enough to be useful for both. As a sidenote, I really think Google is missing an opportunity here. Drive could really use a Paper-style competitor. Start with the collaboration foundations of Docs, but remove all the cruft. No font changing, no formatting beyond what's in markdown, remove all the menus, streamline the interface, add some integrations like embedding Sheets-style spreadsheets. They'd capture a lot of marketshare that has G-Suite domains, but reaches out to other tools to manage ephemeral collaborations and knowledge bases.
