Google Docs is an online word processor and part of the free, web-based Google Docs Editors suite offered by Google. Google Docs is accessible via an internet browser as a web-based application and is also available as a mobile app on Android and iOS and as a desktop application on Google's ChromeOS.

Google Docs allows users to create and edit documents online while collaborating with users in real-time. Edits are tracked by the user making the edit, with a revision history presenting changes. An editor's position is highlighted with an editor-specific color and cursor, and a permissions system regulates what users can do. Updates have introduced features using machine learning, including "Explore", offering search results based on the contents of a document, and "Action items", allowing users to assign tasks to other users.

Google Docs supports opening and saving documents in the standard OpenDocument format as well as in Rich text format, plain Unicode text, zipped HTML, and Microsoft Word. Exporting to PDF and EPUB formats is implemented.
