Prezi is a presentation software that allows users to create zoomable presentations on a virtual canvas. It was created in 2007 by Adam Somlai-Fischer, who believed zooming interfaces allowed exploring information at both an overview and detailed level. Users can sign up for free and get benefits like a unique zoomable interface, versatility, and ability to visually showcase relationships between information. Prezi presentations can hold audience attention better than PowerPoint. However, it has some limitations like fewer features, inability to include animations, and needing an internet connection unlike PowerPoint.
