The main question I have right now is whether your tool generated the landing page of your own product? And I find it odd that your landing page doesn't say that.
I think your landing page itself is pretty good. The over the fold area describes the product very well.
Your testimonials are very impressive and well done, but you are using testimonials of your other product within this landing page generator's page. These people are not saying how great this product is, they are talking about your other product, and implying otherwise is a bit disingenuous. Not a fan of that.
I also found it a bit odd why there are 4 different styles for CTA buttons. One or maybe two would surely be enough.
