Prezi

Since Prezi provides software as a service, you need to register on Prezi.com and create an account before creating your first prezi.

You have access to different licenses, depending on what you need. The Prezi Public license is free, while the Enjoy and Pro licenses come with a yearly recurring payment system. All license levels come with a 30-day free trial of Prezi Desktop. 

By logging in to your Prezi account, you can access your online prezis from any browser. With a Prezi Pro license, you can install Prezi Desktop on up to 3 computers simultaneously. With all license levels, you can share your prezis with others so they can work with you, or simply view your prezis online.
