I will risk to ask stupid question - what is the thing with “AI tools”? Is there something you can describe with your words what kind of WordPress theme you need and it will create theme in few minutes? I don’t check regularly Elements and everything related to AI so I have no idea.
About sales, my sales dropped this month more than usual and I believe that is because of low sales summertime season. In general I think sales are low because of Elements, because of theme licenses without time limit, because there is no real control how licenses are used and because there is no enough marketing for Themeforest.
