"Finally an AI tool that keeps characters consistent."
My main character used to look slightly different on every page, which ruined the book feel. Colorin lets you lock the character and it actually works. Published my second KDP book last month and my niece thought it was hand-drawn.
"The first one that produces beautiful illustrations."
In a few minutes I generated clean coloring pages with defined lines, ready to publish. The book generator makes it easy to have everything in a single PDF. This is the first tool that truly produces a professional visual quality. I recommend it if you want to sell on Amazon or Etsy.
"So easy to use. The service is excellent."
Colorin AI is so easy to use. For a fairly new company you have done really well to build this, and I am now a subscriber because I am genuinely pleased with the service.
