Take a look at Prezi – the online presentation tool
Prezi is a name you might have heard a couple of times if you’re into presentations. It’s an online presentation tool that’s different than most and, because of this, has a lot of admirers. What, exactly, makes Prezi so amazing?
Flash-based
Since Prezi is flash-based, your presentation doesn’t need to be completely linear, like most presentations. Instead, you can easily create a visual map containing anything from words to links.
You can zoom in and out of the image to various ideas, links and images. This eliminates the need for identical slides or backtracking when you have to revisit an idea.
Intuitive
Prezi presentations are created differently than most, which can make it hard to get used to at first. Once you have become comfortable with the program, however, it is like second nature. You can create presentations like you would a thought map, which is fantastic for those non-linear thinkers.
If you are having any difficulty getting used to the user interface, simply check out one of the many tutorials on Prezi’s website.
While Prezi is web-based, it permits you to download your presentation once it is complete. This is especially convenient for anyone who worries about the stability of his or her Internet connection during the presentation. The tool can be used for free or purchased for $59/year for additional storage and privacy.
Prezi is an incredible tool. While not everyone is looking to ditch PowerPoint, this is a great alternative.
