AI Book Cover Generator
Book covers sell by signalling genre before anyone reads the title. Romance uses warm light and a clinch or an illustrated couple. Literary fiction uses restrained typography over a single symbolic object. Thrillers use cold blue, hard shadows, and a lone figure. Fantasy uses illustrated landscapes with a small figure for scale. Naming your genre in the prompt is the shortcut to all of that.
The other thing to get right is where the type goes. Amazon shows your cover as a small thumbnail next to a dozen others, and the title has to be readable at that size. Generate art with a deliberately quiet band at the top or bottom, then set the title and author name in real type over it.

How to get better results
- Say where the title goes: "empty sky at the top" or "quiet band along the bottom". Covers fail when the art fights the type.
- Name the genre explicitly. It carries palette, mood, and composition conventions the model already knows.
- Compose vertically. A landscape image cropped to a book ratio loses whatever made it work.
- Judge it at thumbnail size, because that is how it will be browsed on any storefront.

Recommended model
SDXL's resolution and composition control give you a cover that holds together as a thumbnail and still has detail at full size.
Frequently asked questions
- What size should a Kindle cover be?
- Amazon recommends 2560x1600 at a 1.6:1 height-to-width ratio. Generate the art on Dreamify, upscale it, then crop and add typography to hit that exact size.
- Can I put the title in the prompt?
- You can, but the model will render it as garbled shapes. Generate clean art with room for type and set the title yourself in a real typeface.
- Is AI cover art allowed on Amazon KDP?
- KDP currently allows AI-generated content but asks you to disclose it during publishing. Policies change, so check the current KDP content guidelines before you upload.
