What is Prezi exactly?

Hi there! New to Prezi and just want to confirm what platform this is used through.

Is it an online account that you use on the internet? Or is it a software that has to be installed on your computer to use?

Hello @Sadie_Sutton_Kushell, we offer both an online editor that you can access through www.prezi.com, as well as a desktop application with which you can work offline. The desktop application is available with a Prezi Next Plus or higher license. If you have any other questions feel free to reach out to us.
