Prezi offers different accounts for different users. In the following screenshot, you will find a description of them all, starting with the simplest setup:
You will find this Prezi account overview at www.Prezi.com/pricing.
The public account is 100 percent free. With it, you have full online access to the Prezi program except for a few picture editing tools. Your prezis will be public, meaning that anyone can view them on the Internet. You will have 100 MB storage for your prezis, which is fine for most start up users.
The Enjoy account is a subscription that you pay for after the first month. One of the great features that apply to the paid accounts is the privacy option. This option allows you to choose with whom (if anyone) you want to share your prezis. It also allows you to insert your own logo into your presentations, and gives you better support and 500 MB storage. The Enjoy account offers limited access to some of Prezi's picture editing tools.
The Pro account is a subscription that you pay for. The huge benefit of the Pro account is that you can download the Prezi program to your computer (Windows or Mac). Use this account to work in Prezi without being online. With this account comes 2 GB online storage for your presentations, and you will have access to all of Prezi's picture editing tools.
The Teams account is used for businesses and offers the option of storing custom Prezi templates called "branded themes" and centralized billing, which makes it easy to administer several accounts. You are also offered easier access to support and 500 MB storage.
Students and teachers are offered educational accounts. The educational accounts are called Edu Enjoy, Edu Pro, and Edu Teams. These accounts are the same as the accounts described beforehand, but are offered to students and teachers at a reduced price. You are eligible for an educational plan if you sign up for your edu-Prezi account using a school e-mail address.
