What is KDP Builder?

KDP Builder is a web-based publishing workspace for independent authors, entrepreneurs, freelancers, and small publishing teams. It combines book planning, AI-assisted writing, editing, cover design, interior formatting, and publishing metadata so users can prepare a book without moving between separate tools for every stage.

Authors can start with an idea or bring an existing manuscript or interior. Guided workflows support novels, nonfiction, children's books, cookbooks, memoirs, puzzle and coloring books, journals, planners, and workbooks. Chapter review and locking controls keep authors involved throughout drafting. The Design Studio adds editable templates, layers, typography, print guides, and AI artwork editing. Available outputs include EPUB, DOCX, print-ready PDFs, cover files, descriptions, keywords, categories, author bios, and upload checklists, depending on the workflow.

Files are downloaded for the user's chosen publishing platform, including Amazon KDP, IngramSpark, and Lulu. Quigglys LLC operates KDP Builder independently of Amazon. Users retain commercial rights and review their work before publication.
