Your book, designed for you. Money back if it is not right.

Vellum and Atticus are do-it-yourself apps — you buy the software, learn it, pick a template, and lay out every page yourself (and Vellum is Mac-only). They only do the interior. Cantos does the work for you: upload your manuscript and it reads it, makes the design decisions, and hands back a finished interior, custom cover, and complete marketing kit — on any device, in minutes.

Books where the words carry the weight — fiction (literary, mystery, thriller, romance, sci-fi, fantasy, historical), memoir, and text-forward non-fiction (business, self-help, how-to). There's a dedicated large-print design for accessible editions. We're not the right fit for children's picture books, cookbooks, or heavily illustrated reference and textbooks that need page-by-page art direction.

Yes, and they're included — not an upcharge. Alongside your press-ready PDFs you get an editable DOCX master of your interior and a layered PSD master of your cover, with every element on its own layer. Most services lock your project in their app or charge hundreds for source files. Your book is yours — all of it.

PDF/X-1a (print-ready, all fonts embedded — paperback and hardcover), DOCX (Word), and ePub 3 (the universal eBook standard for Kindle, Apple Books, Kobo, and more). All three in every order, ready for KDP, IngramSpark, and Lulu.

This is not machine-gloss. Cantos reads your whole book first, locks a glossary and a per-character voice, adapts idioms for the new reader, and sets dialogue in the new language's own typography — the raya and guillemets done right. It's validated by round-trip testing, and every edition ships with a side-by-side bilingual review document. Try a free translated sample of your opening before you buy.

Your work, your copyright. Everything you upload stays yours; BookDesignerAI claims no copyright on your book. Your content is sent securely only for the duration of the work you asked for, is never used to train AI models, and is never shared with third parties. You can delete your files or your entire account at any time.

This is a professional production tool that delivers human-level results — not a quick AI gimmick that spits out something you then have to fix. Cantos was developed over two and a half years of painstaking work, refined against decades of manuscript review know-how until the output could stand beside a book from a professional design house.

Behind it is a rare combination of expertise: book design and typography, deep knowledge of the book industry and self-publishing, serious software engineering, and the very latest in frontier AI-model research. Most tools have one of those. Turning a manuscript into a press-ready, beautiful, correct book takes all of them working together — which is exactly what Cantos is.

The result is work that passes professional scrutiny and real-world standards: print-ready files that sail through KDP and IngramSpark preflight, typography that reads like a designer set it, and covers built to exact spine and trim specs. You get the quality of a professional production team — at a fraction of the cost and the wait.

At $99.99 to start, Cantos out-values both ends of the market. It's less than the do-it-yourself apps — Atticus is $147 and Vellum is $249 — and unlike those tools, it's done for you, not handed to you to learn and operate. And it's a world apart from the free "AI book" tools, which make one quick pass through a small model and hand you the rough, one-shot results the internet calls "AI slop" — which you then spend days fixing.

Cantos works like a professional studio. It runs on the best, highest-end AI models available and puts your manuscript through many specialized passes — structure, copy editing, typography, layout, cover design, and quality review — each one checked and refined. That depth costs real computing power on every single book, and it took years of work to build and tune.

What you get back is a book that's actually ready to publish — files that sail through KDP and IngramSpark, typography that reads like a designer set it — not a draft you have to rescue. Better results than the cheap tools, done for you unlike the apps, for less than you'd expect.

Your book is yours. The story, the voice, the years of work, the imagination — that's you, and nothing here changes a word of it without your say-so. We are not in the business of writing or replacing your art. We are in the business of getting your finished creative work across the finish line and out into the world.

Think of Cantos as a tool, not the author — the way a word processor, a camera, or a printing press is a tool. The hard, beautiful, human work of making the book is already done by you. What used to take weeks of fighting with margins, fonts, spine widths, and export settings — or thousands of dollars and a long wait on a designer — now takes minutes, so your brainchild reaches readers while the fire is still in you.

We love creators. We love the art, the joy, the imagination, and the knowledge that human beings bring into the world. AI doesn't take any of that away — here, it simply clears the technical hurdles between your manuscript and a professional, published book. You bring the creativity. We just help you cross the finish line.

Word can absolutely produce a professional book — with the right templates. We've sold Word book design templates at BookDesignTemplates.com since 2011; that's the right route for DIY authors and for genres we don't handle here (cookbooks, children's, illustrated nonfiction).

Cantos is the done-for-you path for novels, memoirs, and fine literary work. Upload, and it handles interior layout, print-ready PDF, ePub, copy editing, and a complete marketing kit — in minutes. ChatGPT can draft copy but can't produce press-ready files. Cantos can.

Your interior is professionally formatted in grayscale (black & white) — the standard for novels, memoirs, and literary books. It also keeps your printing cost low: color interior printing costs significantly more per copy, which would eat into your royalties. Photos in your manuscript come through in crisp grayscale, and interiors use clean professional margins (no full-bleed, edge-to-edge interior printing). Your cover is designed in full color, and your eBook keeps your images in full color too — the grayscale conversion applies only to the print edition.

Each component you buy adds Universal Revision Passes to one shared pool you can spend on anything — formatting, grammar, cover image, or cover typography. Interior includes 10, Cover 20, Grammar 5, and the Marketing and Book Premiere Kit 5 — so the Full Package comes with 40 passes pooled together. Most authors are done in a round or two. Need more? A Universal Revision Pass is $25 for 5, usable on any step — each re-generation is one pass.

Human designers typically include 2–3 rounds of revisions and then bill by the hour for additional changes — that's how revision costs balloon. We just include far more: a generous shared pool that grows with whatever you buy, and if you ever want more they're $25 for 5 — one simple pass that works on your interior, grammar, or cover alike.

Checkout is securely powered by PayPal. Pay with your PayPal balance, or with any major credit or debit card — Visa, Mastercard, American Express, or Discover — no PayPal account required. Your card details go straight to PayPal over an encrypted connection; we never see or store them.

At checkout, PayPal may also offer Pay in 4 (split your purchase into four payments) or other financing options — at PayPal's discretion and subject to their eligibility — a handy way to spread the cost of your book over time. Availability and terms are set by PayPal, not BookDesignerAI.

Cover Studio designs your book's cover and outputs three files per project: paperback wrap (front + spine + back, with bleed and exact spine width calculated from your page count), hardcover case wrap (with hinges and trim), and eBook front cover. Each file is sized to spec for KDP, IngramSpark, and Lulu — upload and publish.

Cantos starts by reading your title, author, and your cover brief, then generates three concept directions for you to choose from. Pick one, and Cantos picks fonts and colors that match your book's mood — then tell it what to change and it refines the design. Output is print-ready PDF/X-1a (the publishing standard) plus high-res JPG — and you can check every printer you publish with (Amazon KDP, IngramSpark, Lulu) to receive press-ready files for each, sized to that printer's own spine and bleed spec.

A cover is $99.99 (or 3 books for $199.99). Add it to any project in the cart — pair it with an Interior and the bundle discount kicks in automatically — or buy it standalone if you've already formatted your interior elsewhere.

Yes. Bring a front-cover image or a full wrap (back + spine + front) and Cantos does the rest — your title and author set as real typography, and print-ready files built to your publisher's exact specs. Bring a front-only image and Cantos gives the spine and back a complementary color drawn from your artwork, so the whole wrap feels designed. Perfect for authors working with an illustrator, or with artwork they already love. Same price either way.

Generic AI image tools give you a square JPG. Beautiful, sometimes — but a book cover isn't a JPG, it's a precisely dimensioned wrap with a spine, hinges (for hardcover), bleed, and per-platform safety zones. Cover Studio handles all of that: spine width is computed from your page count and paper stock; trim and bleed match your book's exact dimensions; safety margins are auto-checked on every text element; output is print-ready PDF/X-1a sized to KDP, IngramSpark, and Lulu specs. Upload directly — no cropping, no guesswork.

Phase 1 alone delivers eighteen pieces: six descriptions and copy pieces (back cover, Amazon, short, long, 100-word, hook/pitch), four Amazon & retail assets (keywords, keyword boxes, BISAC, comp titles), and eight author/media pieces (author bios, press release, bookstore pitch, social posts, interview questions, cover brief, publishing checklist). Phases 2 and 3 add the launch and press pieces — the media one-sheet, pitch letters, and your six-month promotion calendar — bringing the full kit to around thirty. All generated from your manuscript.

Yes: your book can be published in all six languages Cantos builds in — English, Spanish, French, German, Portuguese and Italian. Start your book in any one of them, then add a complete edition in any of the other five — same design, same story, ready for readers in a new market.

Yes — and it's a complete second edition, not just translated text. The Language Pack has Cantos translate your whole book with true literary care: your final, perfected book, every revision included, into Spanish (your choice of Mexican / Latin American, Peninsular, or neutral), French (standard European or Cajun / Louisiana), German (standard German (Germany), Austrian, or Swiss Standard German), Portuguese (Brazilian or European), Italian, or English — every book can add editions in the other five languages.

Your cover is re-set with your same artwork, your Marketing Kit is rewritten for the new market, and a side-by-side bilingual review document lets you verify every paragraph. Try a free translated sample of your own opening before you buy — $199.99 per language, per book. English, Spanish, French, German, Portuguese and Italian are available today — German in standard German (Germany), Austrian, or Swiss Standard German, and Portuguese in Brazilian or European Portuguese.

The site and the app are in English, Spanish, French and German. A book in one of the other two is laid out, copy edited, covered and translated in its own language; you simply read the buttons in whichever of the four suits you.

Your projects and files stay on your account, ready to download whenever you need them. We still recommend downloading your final PDF, DOCX, and ePub and keeping your own copy — a good backup habit for any author.

Yes — that is PDF to Manuscript, $99.99 a book. Send the PDF of a finished book, even one already laid out for print, and you get a clean, editable Word manuscript back: US Letter, double spaced, chapters as real headings, bold and italic kept, footnotes rebuilt as real Word footnotes, and the page numbers, running heads and old contents page taken out (and handed back separately, never silently deleted). A free determination runs first and answers yes or no with the measured numbers, so a no costs you nothing, and $49.99 comes off the Interior if the same book goes on to a fresh layout. We do not sell it for scans with no text layer, and you must hold the rights to the text.

Often, yes, and finding out costs nothing. Upload the file your printer turned down at the Rejection Clinic and Cantos runs the same conformance checks they run, naming every finding in plain words and saying for each one whether we can put it right inside the file. The Print File Fix is $49.99, one flat price covering whichever of your files we can repair — the cover, the interior, or both — and nothing is charged unless the repaired file passes its own re-check. Some things honestly cannot be fixed in a finished PDF, such as a font that was never embedded or the wrong page size, and the diagnosis names the route out instead of taking your money.

That is the Backlist Second Edition, $179.99 for the whole thing in one purchase: the manuscript recovered from your PDF, the interior set fresh in a design you pick, and a new cover — bought together rather than as three separate steps, with no second checkout later. A free determination runs on the PDF first, so you know it will work before you pay anything.

Yes. The Large Print Edition is $99.99 and makes your whole finished book again at 14 point in our dedicated large-print design — it is a fresh setting, never a font toggle on the file you already have. The contents page is re-baked against the new page numbers, your cover is re-rendered for the new spine (your own artwork by default, or a fresh one if you prefer), and the edition carries its own ISBN. It is offered at 6x9, 7x10 and 8.5x11: 14 point does not sit honestly on a smaller page, so we do not pretend otherwise.

Yes. The Accessible ePub is $49.99 and is built for a reader rather than for a shop window: real navigation and landmarks, semantic structure, a declared language, and a description for every picture — delivered with an accessibility report you can hand to a retailer that asks for one. It works from your manuscript or from the ePub of a book we already built, and a free determination runs first.
