KDP Builder
The complete AI self-publishing studio for Amazon KDP
About KDP Builder
KDP Builder is an AI book creation studio for self-publishers. In one guided workflow the AI drafts the manuscript chapter by chapter, builds a print-ready interior, designs a genre-aware cover and writes the listing metadata, then hands it all over as one ZIP for Amazon KDP, IngramSpark, Lulu or your own store. Self-publishing usually means juggling a writer, formatter, cover designer and metadata writer, and wrong trim, bleed or spine settings get files bounced. KDP Builder puts those steps in one place and checks the print specs before download.
It covers 18+ book types, from non-fiction and novels to children's, puzzle, coloring, cookbook, planner and journal books, each with a credit estimate before you start. Credits come from a subscription or from one-time packs that never expire. The free start is 75 one-time welcome credits that expire after 14 days, with watermarked exports. The site states it is not affiliated with Amazon, its usage figures (such as 4,915+ authors) are its own claims, and it does not name the AI models it uses.
Choose a book type and add your topic, audience and goal. Optional niche and competitor research analyzes competing titles to show gaps before anything is written.
The AI drafts each chapter while keeping the voice consistent; you edit, approve and lock as you go. The interior gets drop caps, running headers, margins and bleed, and can be edited page by page.
Design the cover in the Design Studio, then review the blurb, keywords, categories and metadata - nothing is final until you approve it. Download one ZIP with the cover PDF, interior PDF, EPUB, DOCX, metadata and an upload checklist, and upload it yourself.
- •Guided Six-Step Workflow - Book type, idea, manuscript and interior, cover, package review and download, with a credit estimate shown up front.
- •Chapter-by-Chapter Drafting - The AI writes each chapter while you keep approval over every page.
- •Print-Ready Interiors - Typeset interiors, plus a free KDP interior formatter that turns an existing DOCX, PDF or page images (up to 120 pages) into a KDP-ready PDF.
- •Design Studio and AI Covers - Ebook covers, paperback wraps with spine and hardcovers, 161 templates, layers and AI tools to erase objects, expand or remove backgrounds and generate artwork.
- •KDP Compliance Shield - Spine-width, bleed, trim and safe-zone checks before download, and an AI content disclosure reminder in every export.
- •Complete Publishing Package - Cover, interior, EPUB, DOCX, blurb, keywords, categories, description and author bio in one ZIP, with full commercial rights.
KDP Builder suits self-publishers and KDP authors who want a complete book without hiring separate freelancers, and low-content publishers making puzzle books, coloring books, journals and planners in volume. The Studio and Agency plans target studios producing several books a month, and authors with a finished manuscript can use the free formatter alone. Costs vary by book: a text-only journal runs about 75 credits, a novel 125 to 450, so occasional authors may prefer a pack. Failed generations are refunded in credits. Uploading and disclosing AI content to Amazon remain your job.
