Feature
AI book cover generation that knows your genre.
The model has studied thousands of bestselling covers. It knows romance from thriller from fantasy. You describe the book — it composes a cover.
BookCovers' AI generates book covers tuned to genre conventions in 10-30 seconds. Free models (Stable Diffusion XL, Flux Schnell) cost $0; premium models (Flux Pro, Recraft V3, Ideogram, DALL-E 3) cost between 1-8 credits per generation, charged from a top-up wallet that never expires. The output is composed for a real book cover at the trim size you select — not a 1024x1024 square you have to crop later.
Genre is the first input, not an afterthought.
Pick romance and the model leans into warm tones, soft lighting, script + serif type pairings, and couple imagery. Pick thriller and you get high contrast, single-subject compositions, and bold sans-serif. Fantasy gets epic landscapes and dramatic lighting. The genre signal is part of the prompt the AI sees — not a tag that gets ignored.
12+ genres modeled out of the box.
Romance, fantasy, thriller, sci-fi, non-fiction, mystery, horror, children's, YA, business, memoir, cookbook, self-help, historical fiction. Each one has its own visual language. The AI was tuned on bestseller datasets per genre, not a generic Stable Diffusion checkpoint.
Multiple variants per generation.
One prompt produces multiple takes. You pick the strongest direction, regenerate, or fork into the canvas editor for manual refinement. The AI proposes — you decide.
Iterate inside the editor.
Open Cover Chat in the canvas: "Make the title 30% larger and warmer." "Replace the sky with a stormy sunset." "Try a serif title." The AI generates new variants while preserving your edit history so you can compare and revert.
Choose your model.
Free tier covers SDXL and Flux Schnell — solid for most use cases. Pro unlocks Flux Pro (best photorealism), Recraft V3 (best typography), Ideogram (best for text-in-image), and DALL-E 3. The cost in credits is shown before you generate.

Frequently asked questions
Which AI model is best for my genre?
Flux Pro for photorealistic romance and contemporary covers. Recraft V3 for typography-heavy non-fiction and business books. Ideogram for covers with crisp readable text. SDXL (free) is solid for fantasy and sci-fi. The editor shows the cost in credits before each generation.
Does the AI know KDP trim sizes?
Yes. Pick a trim size first (5x8, 5.5x8.5, 6x9, etc.) and the AI generates the front-cover artwork at that aspect ratio with the right margins for KDP and IngramSpark bleed.
Can I use the AI output commercially?
Yes. Pro plan covers come with a full commercial license — print, ebook, audiobook, ads, social. No attribution required.
How does this compare to Midjourney?
Midjourney makes a 1024x1024 image. BookCovers composes a full cover at trim size, with the title, author, and back-cover layout placed automatically. Midjourney users typically spend 1-3 hours in Photoshop after generation; BookCovers users spend minutes.
Is the free tier really free?
Yes. 1 cover project, full canvas editor, free AI models (SDXL + Flux Schnell). The export carries a watermark; Pro removes it for $5/mo.
Free models, free first cover. Premium models for $5/mo. Real print-ready output.
