How it works

From one idea to your bookshelf.

Your romance contract

“The slow burn needs to stay slow.”

You know the contract. He can be a billionaire without becoming a bully. She keeps her backbone. The first kiss comes after trust, not on page three. Your book keeps every promise, from sweet to open door.

Dr. Christian Mayer, founder

Your version might sound like this “Dual POV. No cheating. No surprise pregnancy. She initiates the first kiss. He says ‘I love you’ first. Give me a real grovel and a happy ending that feels earned.”

What you can make

The exact book you want to read.

A slow burn that earns its payoff, a morally grey hero who stays grey, or a mystery you can't put down. Each arrives complete, with a cover, ready for your Kindle.

Whatever formula you used to come up with a design for my book was spectacular and really pulled from the premise of the book.

Real opening lines

Read how they begin.

The first lines of two gallery romances, each from a single prompt. Unedited.

Blueprint for a BlizzardChapter 1 · Wrong Key

By the time Nadia Reyes reached the Aspen Lodge, the snow had erased the driveway, the parking lot, and most of her patience. Her rental SUV sat at an angle beneath a drift.

Her voice, from line one

Prompt: a witty, dialogue-rich enemies-to-lovers romance about rival architects trapped for five days in a snowbound lodge with one room and one bed.

Altitude Between UsChapter 1 · Weather Window

Rain turned the private terminal windows into sheets of mercury, swallowing the lights of Le Bourget one by one. Beyond the glass, the runway gleamed black and empty.

Cinematic, not generic

Prompt: a slow-burn romance rich in dialogue between a Manhattan tech billionaire and a famous K-pop star, much of it aboard their private jet.

Questions, answered.

What you get, what it costs, and what stays yours.

Trial & billing

What does the trial include?

Your first 10,000-word book is written before you enter a card. Downloading it starts a $0, 7-day trial; the first $29.99 monthly charge happens after 7 days. Cancel anytime before day 8 and pay nothing.

Do I need a payment method to start?

Not to write your first book. A $0 card checkout comes only when you download it, and starts your 7-day trial. Prefer no subscription? You can keep your book with a one-time purchase instead.

What you get

Can I ask for changes without editing every paragraph?

Yes. Use Manuscript Rewrite and describe the result you want: rename a character, expand a chapter, change the tone or create a longer edition. Your original stays available.

Can I make small edits while I read?

Yes. Open your book in the online viewer and use its line-editing tools. For bigger changes, describe them in Manuscript Rewrite.

What kinds of books can I make?

Most people write romance and romantasy series. You can also make fantasy, thrillers, mysteries, memoirs, practical guides and family storybooks. Books are text with a designed cover; there are no illustrations inside.

Can I read it on my Kindle?

Yes. Choose Kindle on your book's page and it lands in your Kindle library within minutes. The EPUB also works in Apple Books and Kobo.

How spicy can it get?

You choose the heat (sweet, fade to black, or open door, written with feeling rather than graphic detail) and how many spicy scenes (one, a couple or a few). Fully explicit scenes are currently not available. Characters in intimate scenes are always adults, and open-door books are for readers 18+.

Do I need writing experience?

No. Start with a rough idea, a favorite trope, or the story you have been carrying around. You can add as much direction as you like.

How long does it take?

Generation time depends on your chosen target book size:

  • Short Book (5,000 words): ~4–10 min
  • Small Book (10,000 words): ~6–15 min
  • Medium Book (20,000 words): ~12–30 min
  • Large Book (40,000 words): ~25–60 min
  • Extra Large Book (80,000 words): ~50–120 min
  • Epic Book (120,000 words): ~75–180 min
What is the difference between New Book and Manuscript Rewrite?

New Book writes a new book from your idea, outline or notes. Manuscript Rewrite edits a book you already have (polish, translate, shorten, expand or change chapters) and keeps everything you don't ask to change.

What are the input limits for New Book and Manuscript Rewrite?

New Book accepts up to 20,000 words total across your typed prompt and attached document. Manuscript Rewrite accepts an existing manuscript of 1,000–200,000 words, with up to 64 source sections and 3 MB of extracted text; describe the changes separately in the instruction box (up to 20,000 words). Both support Word (.docx), text, Markdown, and HTML. Word uploads can be up to 20 MB; other New Book attachments can be up to 1 MB. These are input limits, separate from your chosen finished book length.

Can I upload a long brief or outline instead of a manuscript?

Yes. Attach it in New Book: outlines, character notes or research, up to 20,000 words in total. Use Manuscript Rewrite only for existing book text you want edited.

Which writing engine do I get?

Both, on every plan, chosen per book. Lyra is the default at standard credits. Lyra Max is our alternative premium engine at 3× credits.

Which AI models power Lyra?

Lyra currently uses OpenAI GPT-6.1 Sol with high reasoning for core planning and chapter writing. Lyra Max uses GPT-6 Astra, with high reasoning for planning and the opening chapter and medium reasoning for later chapters, at 3x credits. Short formatting tasks, safety checks, and cover images use settings and models suited to their jobs. Existing books retain their original engine configuration.

Can I try different covers for the same book?

Yes. Paid plans include a monthly bonus gift of cover recreations: 4 on Author, scaling with each higher plan, without spending book credits. You can spend several on one book, switch among the retained versions, and download whichever cover is currently selected. Only successful recreations count.

Can I match my own writing voice or paste writing samples?

Yes. Paste a sample and add direction for tone, pacing, POV and words to avoid, like “dark but tender.” Your guidelines carry through the whole book.

Can I generate books in other languages?

Generally yes. We have tested English and German most, and major languages should generally work as well, though results can vary by language and topic.

Can AI write a book from one idea?

Yes. ImagineYourBook is built to expand a single idea or prompt into a structured, full-length book draft — chapters, flow, and a cover — that you can then read, edit, and publish.

Is this different from ChatGPT?

Yes. Instead of chatting paragraph by paragraph, ImagineYourBook plans the whole book, writes it chapter by chapter for continuity, designs a cover, and hands you a finished book as both a Word file and an EPUB — ready to edit, read on any e-reader, or publish.

Publishing & rights

Do I own the result?

Yes. You keep the rights to what you generate.

Can I use the book for business or sell it?

Yes. Commercial use is allowed, including selling books, as long as you do your own final review.

Can I publish a book written with AI on Amazon KDP?

Yes. You own what you generate and can self-publish on Amazon KDP or elsewhere. Use the Word manuscript (or the EPUB edition) and JPG cover, and do your own final review before publishing.

Series & sequels

Can I write a sequel or a whole series?

Yes. Mark a book as part of a series and every next volume starts from continuity context compiled from the books before it: characters, world rules, open plot threads, invented terms, and the final scenes of the previous book so the voice carries over.

Why write a series?

Because you get to stay in the world you love, picked up exactly where Book One ended. If you publish, readers who love Book One buy Book Two.

Content types

Can I create a personalized book gift?

Yes. Many people use it to create personalized book gifts — a proposal book, anniversary keepsake, family storybook, or birthday surprise — built from your own names, memories, and details.

Can I create a children's book?

Yes, as text: gentle, age-appropriate stories to read aloud, built from your child's names and details. Books are text-only, so there are no picture-book illustrations.
