Prezi is a cloud-based presentation platform that allows users to create engaging and dynamic presentations. Unlike traditional slide-based formats like PowerPoint, Prezi uses a zooming user interface, enabling a more fluid, non-linear presentation style. This makes it ideal for storytelling, educational presentations, and business pitches, as users can navigate through their content in a more interactive and visually captivating way. Prezi is popular in various fields, including education, marketing, and corporate settings, due to its versatility and ability to hold the audience's attention.
