Prezi is a cloud-based (SaaS) presentation software and storytelling tool for exploring and sharing ideas on a virtual canvas. Prezi is distinguished by its Zooming User Interface (ZUI), which enables users to zoom in and out of their presentation media. Prezi allows users to display and navigate through information within a 2.5D space on the Z-axis.

Prezi is used as platform for bridging linear and non-linear information, and as a tool for both free-form brainstorming and structured presentation. Text, images, videos and other presentation media are placed upon the canvas, and can be grouped together in frames. Users then designate the relative size and position between all presentation objects and may pan and zoom in and between these objects. For linear presentations, users can construct a prescribed navigation path.

Prezi was initially developed by Hungarian architect Adam Somlai-Fischer as an architectural visualization tool. Prezi’s stated mission is to “make sharing ideas more interesting”, and it is intended to be an intuitive tool to develop and share ideas as a visual narrative.
