Google Docs is an online word processor made by Google. It grew out of Writely, a web based editor that Google bought in 2006. Docs is part of a suite with Google Sheets for spreadsheets and Google Slides for presentations.
Several people can edit the same document at once and see each other's cursors. Changes save automatically, and version history shows who changed what and when. Comments and suggestion mode let reviewers propose edits that the owner can accept or reject. Docs can open and export Microsoft Word files, PDFs and other formats. Offline mode lets people keep working without an internet connection.
Docs is free with a personal Google account, and files count toward its 15 GB of storage. Businesses and schools usually use it through Google Workspace, which is a paid plan with admin tools and more storage. Google Workspace for Education gives schools free and paid options, which has made Docs common in classrooms. Docs runs in the browser and has apps for iOS and Android. It is a popular alternative to Microsoft Word for shared writing.
