Microsoft Sway is a presentation web app that allows users to merge text and media to create a presentable website.
Sway is an intelligent app that helps gather and format your ideas and present them on an interactive, web-based canvas. To create a Sway, add pictures, text, documents or other content, and Sway will make it look great. To read a Sway, just tap to open it and then scroll or swipe through the story. It appears to be better suited to personal displays than for formal presentations.
