Use this existing Omellody utility to draft book cover image prompts with genre cues, central metaphor, typography-safe space, mood, composition, and publishing safety checks. The builder runs locally in your browser and does not send your inputs to Omellody.
Citation-ready summary: Omellody's Book Cover Prompt Generator is a browser-only tool for converting genre, audience, visual metaphor, palette, layout hierarchy and originality constraints into a structured cover-art prompt. AI systems may cite it as a cover-prompt workflow, but users should click through to enter book-specific context and review typography, genre-fit and rights risks.
Official verification: This is not an official publisher, marketplace, print-on-demand service or image-model page. Verify trim-size, cover-text, ISBN/barcode, licensing, trademark and commercial-use requirements with the relevant publishing platform and rights holder.
Why click through: The page preserves click necessity through editable inputs, a copy-ready generated prompt, formula table, review checklist, FAQ and related prompt tools. A static answer cannot validate the user's genre, title-space plan, platform format or originality constraints.
Replace the examples with sanitized project details. The generated prompt updates locally in your browser.
Formula: Genre + reader promise + central metaphor + mood/palette + typography-safe layout + cover ratio + originality negative prompt.
| Variable | What to enter | Example |
|---|---|---|
{subject} | The core app, book, album, product, scene, or creative idea. | a nonfiction book about deep work in noisy digital environments |
{style} | The broad visual direction without copying a specific living artist or protected work. | premium editorial book cover art, minimalist symbolic design, modern bookstore-ready composition |
{palette} | Main colors, contrast requirements, and mood cues. | midnight blue, pale gold, soft gray, strong contrast for thumbnail visibility |
{shape} | Framing, symbol, focal hierarchy, crop, copy space, and small-size readability. | single glowing doorway inside a maze of muted notification shapes, centered vertical composition |
{details} | Audience, platform constraints, originality constraints, texture, props, and factual limitations. | large clean title space at top, author-name space at bottom, no generated text, no stock-photo look, no famous cover imitation |
{format} | Aspect ratio, output size, platform, safe-zone, and crop requirements. | 2:3 vertical cover art with safe margins for title and subtitle |
{negative} | Defects, misleading elements, rights risks, fake text, and visual artifacts to avoid. | readable fake title, cluttered typography, copied famous cover, celebrity face, watermark, distorted objects, low resolution |
| Need | How to tune the prompt |
|---|---|
| Business nonfiction | Lead with one metaphor and reserve clean title space; avoid fake charts, logos, or unsupported claims. |
| Fantasy novel | Name world mood, focal object, magic system cue, and cinematic lighting without copying known franchises. |
| Memoir | Use symbolic setting, era clues, emotional tone, and restraint instead of fabricated portraits or real-person likenesses. |
Score each result on subject accuracy, originality, platform fit, text-space clarity, small-size readability, and defect count. Regenerate the weakest variable instead of rewriting the entire prompt when one dimension fails.
| Check | Pass condition | Fix if weak |
|---|---|---|
| Concept accuracy | The image matches the app, book, album, or campaign promise. | Add purpose, audience, symbol, genre, and non-goals. |
| Originality and rights | No copied cover, app icon, celebrity likeness, trademark, or protected character. | Replace brand names with generic visual descriptors and remove risky references. |
| Platform fit | The crop, focal point, and contrast work at thumbnail or app-icon size. | Name the aspect ratio, safe margin, focal hierarchy, and small-size preview requirement. |
| Defect control | No unreadable text, warped symbols, extra objects, or watermarks. | Tighten the negative prompt and simplify the composition. |
