Color coding authors' contributions in a Google Doc
AuthorViz is developed by Hana Research Lab at the University of California, Irvine. It visualizes authors' contribution in a co-authored document on Google Docs. It color codes who wrote what within your final revision of the document. Extending the existing Revision-History feature within Google Docs, AuthorViz takes the entire history into account rather than one-revision-at-a-time view.
Trung Nguyen is the original developer and Kenny Pham takes it over. We also thank James Somers for his advice on getting the accurate data from Google Docs without using the Google API.
