Prezi is a presentation platform that offers an alternative to PowerPoint. The Prezi secret sauce is its rethinking of how presentations are structured. Instead of creating a series of slides, with Prezi you put everything – text, graphics, charts, quotes – on a single canvas and trace a path, which zooms in and then back out, as you travel from one idea to another. What viewers experience is an animated tour of your concepts, rather than slides marching by one by one.
