1. Scene -> goal, conflict, hidden want
2. Manuscript -> trim, margins, AI disclosure
3. Cover -> page count drives spine width
4. Export -> PDF, EPUB, DOCX, checklist
Use It First
The first product rule: no mysticism. A buyer should be able to enter book facts, get the cover math, and know exactly what remains before KDP upload.
Scene Packet
KDP Upload Checklist
These are source-linked checkpoints, not legal advice. The app should hyperlink Amazon's current pages so the user can verify the rule before upload.
Manuscript
- Final trim size chosen before cover is built.
- Bleed and margins checked for print layout.
- Images are at least 300 DPI for print quality.
- eBook manuscript does not include the cover image inside the file.
Cover
- Paperback/hardcover cover is a single PDF: back + spine + front.
- Page count is final before cover wrap is generated.
- No spine text unless page count is over 79 pages.
- Kindle cover is JPEG/TIFF, ideal 2560 x 1600 px, under 50 MB.
Publishing Form
- Title, subtitle, author, description, categories, and keywords ready.
- AI-generated text/images/translations disclosed when required by KDP.
- AI-assisted editing/brainstorming separated from AI-generated final content.
- Final preview checked in KDP Print Previewer before publishing.
Cover Lab
KDP's cover tools are the fallback. The better workflow is book-derived: read the manuscript, outline the visual scene, generate roughs, choose a direction, then build the print wrap in layers.
Cover Source
Layered Prompt Pack
Wave 1: Roughs
Generate 4-8 small compositions from the book motif. Judge only silhouette, shelf signal, and emotion. Do not add title text yet.
Wave 2: Layer Build
Generate front art, background extension, spine texture, and back-cover atmosphere separately. Composite them into the Bookforge engine cover wrap after page count is final.
Wave 3: Type + KDP Proof
Add title, author, subtitle, spine text, barcode safe area, and blurb in layout software or code. Then verify dimensions with the KDP calculator and Print Previewer.
- User choice matters: the app should let the writer pick the strongest rough before spending time on final art.
- Book contents drive the art: the prompt should come from manuscript themes, character pressure, setting, motifs, and genre shelf expectations.
- Generated art should have no text: typography belongs in the final cover layout, not in the image model output.
Source Links
The app should keep these links visible, because KDP rules change and upload rejection usually comes from one missed mechanical detail.
