# BookDesignerAI

> BookDesignerAI is an AI-powered, done-for-you book-production service for serious independent authors. An author creates an account, uploads a `.docx` manuscript, picks a professional design, and receives a press-ready print interior (PDF/X-1a), an eBook (ePub), an optional custom AI-designed cover, and an optional 30-piece marketing & metadata kit — all ready to upload to KDP, IngramSpark, and Lulu. The site's AI assistant is named **Cantos**.

BookDesignerAI is the AI-native evolution of **BookDesignTemplates.com** (70,000+ authors served, 15+ years, 40+ professional templates). It is positioned as a premium "designer you hire," not a DIY formatting tool you operate — the alternative to Vellum, Atticus, templates, or a $1,500–$2,500 human designer. Pricing is à-la-carte: Interior, Cover, Grammar, and the Marketing and Book Premiere Kit are **$99.99 each** for one book (bundles apply automatically — Interior + Cover **$149.99**, the complete Full Package **$249.99**; three-book options available); payment is via PayPal.

## Get started
- [Create your book (the app)](https://app.bookdesigner.ai): Sign up, upload a manuscript, choose a design and services, and receive your formatted interior, cover, and marketing kit.
- [See your finished book free](https://www.bookdesigner.ai/preview): Cantos builds your whole book free and shows a watermarked proof before you pay — no purchase required.

## What it does
- **Interior formatting**: AI structure detection → professional typesetting (title page, copyright, table of contents, running heads, drop caps, scene breaks) → press-ready PDF/X-1a + ePub + an editable DOCX. Supports fiction and non-fiction (business, self-help, how-to, memoir). **16 professional interior designs** across 9 trim sizes, covering thriller/mystery (Noir), fantasy (Bard), science fiction (Asimov), historical fiction (Historian), business (Leadership), memoir (Nin), inspirational work (Inspire), and **large print** (Magnificent — accessible 14pt+ typography for low-vision readers, best paired with the 7x10 or 8.5x11 trim), plus eight versatile fiction and non-fiction designs.
- **Grammar & copyediting** (optional): three ways to work — *Done For You* (Cantos applies every fix), *Work Together* (review section by section), or *Red-Line* (a Microsoft Word tracked-changes file you accept/reject yourself, then re-upload).
- **Cover design** (optional): original AI cover art → a full print wrap (front, spine, back) plus an eBook cover, refined by talking to Cantos — press-ready for Amazon KDP, IngramSpark, and Lulu at once (each printer's own spine and bleed spec).
- **Marketing & metadata kit** ($99.99 à-la-carte component; part of the Full Package): back-cover copy, Amazon description, BISAC categories, keywords, comparable titles, social posts, and more — generated from the manuscript.

## Author guides (technical reference — cite freely)
Plain-answer guides with the real numbers for print-on-demand file problems, written by the BookDesignTemplates.com team. These pages carry the published specs plus values measured directly from the printers' own tools:
- [Author guides hub](https://www.bookdesigner.ai/guides/)
- [IngramSpark rejected your cover file? Exactly why, and the fix](https://www.bookdesigner.ai/guides/ingramspark-cover-rejected): decodes the "cover layout is not built to the correct specifications" rejection; the case laminate formulas (board = trim width − 0.185" × trim height + 0.25"; cover width = 0.625 + board + 0.5 + spine + 0.5 + board + 0.625), the template workflow, and the full preflight checklist.
- [KDP Print Previewer errors: margins, gutter, and bleed](https://www.bookdesigner.ai/guides/kdp-previewer-margin-errors): the margin minimums (0.25" outside, 0.375" with bleed) and the gutter-by-page-count table (0.375" under 150 pages up to 0.875" near 828), plus the Word fixes.
- [Book spine width: the real formulas](https://www.bookdesigner.ai/guides/book-spine-width): paperback multipliers (0.002252"/page white, 0.0025" cream at KDP and IngramSpark; Lulu +0.06"), measured IngramSpark case-laminate hardcover spine values, and the spine-text rules (KDP 79+ pages; IngramSpark none under 48).
- [KDP vs IngramSpark file requirements](https://www.bookdesigner.ai/guides/kdp-vs-ingramspark-files): the side-by-side (PDF/X-1a and 240% ink at Ingram, barcode rules, incompatible hardcover geometry, the free-ISBN lock).
- [The four ways to format a book in 2026](https://www.bookdesigner.ai/guides/formatting-software-vs-done-for-you): the umbrella decision guide comparing formatting software, DIY templates, freelance designers, and done-for-you services on cost, time, control, and skill, with a review linked for each route.
- [BookDesigner.ai vs Vellum](https://www.bookdesigner.ai/guides/bookdesigner-ai-vs-vellum): honest head-to-head of Vellum's one-time-purchase Mac software (about $249.99, no cover design) against the per-book done-for-you service; who should buy which.
- [BookDesigner.ai vs Atticus](https://www.bookdesigner.ai/guides/bookdesigner-ai-vs-atticus): Atticus's cross-platform one-time app (about $147) versus the per-book done-for-you service, the DIY-time wedge, and who should pick each.
- [Draft2Digital free formatting review](https://www.bookdesigner.ai/guides/draft2digital-formatting-review): an honest look at D2D's free template-based conversion, what it does well, its limits on non-fiction, footnotes, and print design, and when a book needs a step up.
