Writely was a web-based word processor created by the software company Upstartle and launched in August 2005.
Google Docs originated from two separate products: Writely and XL2Web.
Exporting to PDF and EPUB formats are implemented. 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. 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. An editor's position is highlighted with an editor-specific color and cursor and a permissions system regulates what users can do. Edits are tracked by user with a revision history presenting changes. Google Docs allows users to create and edit documents online while collaborating with other users in real-time. 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 Chrome OS. Google Docs is an online word processor included as part of the free, web-based Google Docs Editors suite offered by Google, which also includes Google Sheets, Google Slides, Google Drawings, Google Forms, Google Sites, and Google Keep.
