I bought this once and refunded since I felt it wasn't for me. Then I repurchased because I didn't want to feel like I missed out on something. Spent another 5-7 hours playing with the program and felt like I wasted time.
Ultimately this is my conclusion. This application doesn't allow you to mix Human made content along with AI, and without that you only have AI made content. You can tell right off the bat that it's made by an AI. So now imagine you followed this guru and you paid for their course, and you received an AI video of them not even speaking. I would myself would feel ultimately deceived. There is far too much free YouTube AI content available. If these were courses for yourself or to not be sold, I could see some benefits.
If it is user error and this does take a learning curve to make fantastic courses, then this should not waste credits as you get to learn the software. I tried a few different ways, adding YouTube videos etc, and everything was just okay.
