How to get an AI book cover that actually sells
Your cover is the single biggest click decision a reader makes. Here's how to get one that works.

A book cover that sells obeys its genre's visual conventions, stays legible at thumbnail size, and is designed from the finished book rather than a generic prompt. InkSmith's painter agent derives the cover, spine, and back art from your manuscript and flows it straight into the export.
Cover the genre, not your taste
Readers shop by genre signals — a thriller cover and a cozy-romance cover obey completely different rules of color, type, and imagery. A cover that 'looks nice' but ignores genre convention quietly tells browsers the book isn't for them.
Before generating anything, look at the top 20 covers in your exact subcategory and note what they share.
Design for the thumbnail
Most people first see your cover at the size of a postage stamp. The title must be legible small, the focal image clear, and the contrast high. Detail that disappears at thumbnail size is wasted.
Generate from the finished book
InkSmith's painter agent (Iris) derives cover, spine, and back art from the finished manuscript, so the visual identity matches the actual story rather than a generic prompt. The art flows straight into your PDF/EPUB/DOCX export.
