Office Sway is a presentation program and is part of the Microsoft Office family of products. Sway was offered for general release by Microsoft in August 2015. It allows users who have a Microsoft account to combine text and media to create a presentable website. Users can pull content locally from the device in use, or from internet sources such as Bing, Facebook, OneDrive, and YouTube.

Sways are stored on Microsoft's servers and are tied to the user's Microsoft account. They can be viewed and edited from any web browser with a web app available in Office Online. They can also be accessed using apps for Windows 10 and iOS. An additional app is currently in development for Android.
