TL;DR;
1) I have no clue how they got the images on their site to generate as they did. Nothing I have generated comes close to looking real.
2) The templates you get for your tier are chosen for you
3) There is no way to search or filter on their site in order to find anything within the free or category templates.
4) I'm getting many flagged NSFW images for things that, according to the prompts I give, shouldn't be NSFW

My review:
The images they show on their site and for marketing look amazing, but I have yet to replicate anything that is usable for my purposes. I have tried multiple times with many variations and the only picture that looks good is a generic sunset of a beach. When I tried to do an image in image to put my logo into a scene, it just changed my logo and spat it back out. The next go, it gave me an error image stating that the result was "Not safe for work" (NSFW Content Detected).

I tried some images with people, as the examples they showcase seem amazing. The results using the same AI models look like airbrushed avatars with extra fingers, arms bent backwards or disembodied body parts.

I thought that I would give the templates a try as I do use Canva heavily for my nonprofit and was disappointed to see that I didn't get to choose which categories I could access. I just got access to the generic category. Disappointing, but ok I got the bottom tier. The next disappointment is that there is no way to search or filter the templates. At least none that I can find. If there are 110 free templates and 302 basic templates and they only load 12 templates at a time until you click the "Load More" button.... How am I ever going to come back and find that one template that I saw and didn't have a use for, but a month from now I do? Also, I am not going to sit here and click through 35 pages of little thumbnail images, reading each one and trying to store the information for possible use in the future. These templates have now become a digital paperweight in my book.

I was about to seek a refund (which I didn't know at the time I couldn't actually get with this product) But, I thought that I would try out the t-shirt model first. Maybe I could generate some good designs that I could sell to earn some income for my nonprofit. So, I tried something for my prayer ministry by putting in the prompt: "please generate an image of a dove in white taking flight with a silhouette of praying hands in dark purple in the background". The resulting image, once again, gave me an "NSFW Content Detected." So, for the second time, a photo I tried to generate with religious context was flagged for reasons I can not understand.

Oh, and I normally wouldn't leave a bad review like this without first reaching out to the company. But, from the dashboard, profile, etc... no support button or way to contact them. So, here is my review and my hope that they see this and some things can change so that this app is usable for other clients.
