Google Docs is a free, web-based office suite offered by Google within its Google Drive service. It allows users to create and edit documents online while collaborating with other users live. The word processing, spreadsheet and presentation programs within the suite are named Google Docs, Google Sheets and Google Slides, respectively. The three apps are available as web applications, as Chrome apps that work offline, and as mobile apps for Android and iOS. The apps are compatible with Microsoft Office file formats. The suite also consists of Google Forms, Google Drawings and Google Tables (beta). While Forms and Tables are only available as web applications, Drawings is also available as a Chrome app.
