Google Docs is a free, web-based word processor that allows users to create, edit, and collaborate on documents from any device with an internet connection. Users can share documents with others and invite them to view or edit in real time. Document revisions track changes so collaborators can see who edited what and when. People enjoy using Google Docs because it is simple, free, and enables easy collaboration on documents stored in the cloud. Teachers use Google Docs to have students collaborate on book reports, field trip reflections, stories, science experiments, historical recreations, math problems, newspaper articles, plays, and debates.
