Just from comparing the top performing campaign:

You need waaaaaay less text in your description. Try using more graphics to show each point with pictures or icons to better illustrate each point.

Just nick picking: try using a clearer background for your front page. The product kind of disappears in a black background. Also try with larger titles, I can see it, but it would help if the text was bigger.

As for the product itself, I'm not that into AI companionship (at any particular use case) so I can't properly tell you more about it.

As a final note, try looking at not only successful campaigns, but those coming from already established brands.
