To use Slideator simply upload your slides in whatever format they are currently in. Then you can record a voice-over with or without your webcam turned on. When you have finished recording on Slideator you can share it publicly or keep it unlisted and only share it with a small audience. Watch the short video that I have embedded below to see how Slideator works.
Applications for Education
Slideator provides an easy way to turn an existing set of your slides into a short video lesson to share with your students. You can do similar things with some of the tools built into PowerPoint, Keynote, and Canva. The nice thing about Slideator is that it provides the recording and hosting tools in one place so that you don't have to record and then upload the video to another site.
