It's easy to use and there are some great resources on the site to help you learn how to use it. It can be used by teachers to make their presentations more engaging, and by students to create presentations for their projects.
Once your PowToon is created, you can export it to YouTube or download it. The Chrome extension connects to Google Drive.
There are some short video clips to get you started. It's easy to create a presentation using the build in tools and intuitive interface. Many users say it's easier to use than PowerPoint or Prezi. There are built in characters, props, images and animation tools.
