I bought BIGVU the last time they were on AppSumo. The teleprompter is easy to use and helps me create more professional videos for courses and lead magnets. The AI eye track feature to make your eyes stay on the camera vs going back and forth reading the transcript is pretty cool and looks okay. I don't think it looks very natural, but it doesn't look bad and it is helpful to not have to do a bunch of retakes or have me reading look distracting. If you record a lot of videos this is a great software. Not necessary, but helpful!
