The idea is great, at the intersection of ChatGPT and Midjourney.
I have tested the app but unfortunately I am not super convinced with the results as it feels the text is not super convincing and understand the underlying business proposal of the seller. Regarding the images, it is randomly generated and not linked to the business behind.
Anyway it's a start and it's never too early to launch : ) I got the concept and the concept is great.
