Prezi, an interactive presentation creator
Slide presenting
Description: Prezi is a software for creating interactive presentations. Instead of using traditional slides, Prezi is based on a zooming user interface to navigate through content on a virtual canvas. Users can add text, images, videos, and other multimedia elements to their presentations. It offers both free and paid versions. Signing up for an account is required for use. Prezi was founded in 2009 by Adam Somlai-Fischer, Peter Halacsy, and Peter Arvai.
Evaluation: Prezi is a valuable tool for producing interactive and visual presentations. Its zooming user interface differentiates it from other similar tools. The free version allows storing a few presentations that can be accessed on any device, yet not downloaded. A downside of Prezi’s free version is that presentations can be found and accessed by any user.
Cost: Free public account + paid premium plans.
