I agree with this assessment. The copy is a little to generalized. Just by adding the word Startup to your headline, a reader would get a better understanding about what you do. Personally, I would drop the phrase Artificial Intelligence from the headline. I don't think it's necessary. Instead you should put the benefits you listed in its place.

I think the idea is interesting. I, like you, have found that planning and structuring your prompts give way better results; particularly using structured outputs.
Give away 10 or so images for signing up and then charge a quarter for each down load, giving the user a license to use the image on a website or print run of 100,000 or less. Then encourage users to upload their images and share the revenue with them, 20% would be good. As you get more users you could add different sizes for different prices, $1 for a web image and up to $50 for a bill board size. It worked for istockphoto.com. If this images cover the gamut of genres, I would contact anyone that has anything to do with design, architects, we developers, interior designers.
I have been programming in Java for 7+ years. I am responsible for several site that use struts 2 and Java. In the past year I have been moving toward groovy/grails. I have successfully integrated groovy scripts into production code running srtuts 2. I have also had success with placing an existing struts 2 application into a grails application. The beauty of groovy is that it is built on top of java and compiles to bitecode. Grails is just a convention over configuration approach to a groovy/spring/hibernate or jpa stack. You mantain complete control over all configuration.
I meditate on the Word (Jesus) of God day and night. I also read the Bible and pray. Just talk to him like any friend. I receive peace and incite about things happening in my life.
I also had three years of electical/electronics in college before I started programming. I have been a java developer for eleven years and just recently started programming in groovy. Both of these are native to the jvm and have extensive apis for client and web programming. The grails framework which harnesses the power of groovy, spring framework, and hibernate is like rails in concept but it is its own. If I didn't know these languages, this would be my next move.
