Write cover copy for [BOOK TITLE], a [GENRE AND FORMAT] book for [TARGET READER]. Use [BOOK SUMMARY AND CORE PROMISE], [AUTHOR CREDENTIALS], and [COMPARABLE TITLES OR POSITIONING] as the only source material. Do not invent endorsements, sales results, credentials, media mentions, methods, or outcomes. Create these deliverables: 1. FRONT COVER: 8 subtitle options, each 4-12 words. They must clarify the reader benefit, subject, or stakes without duplicating the title. 2. BACK COVER: 150-190 words in 3 short paragraphs. Open with the reader’s concrete problem, desire, or dramatic situation. State what the book contains and why this author is positioned to write it. End with a precise invitation, not hype.
3. AUTHOR BIO: 45-60 words suitable for a back flap. 4. RETAIL DESCRIPTION: 110-140 words, written for an online listing rather than copied from the back cover. For fiction, foreground premise, protagonist, conflict, stakes, and atmosphere without spoiling the ending. For nonfiction, specify the problem, approach, reader, and realistic result; do not promise transformation the manuscript cannot support. Match the conventions of the stated genre and avoid clichés, vague claims such as “essential,” and generic phrases such as “a journey.” Before answering, check that every claim appears in the supplied material. Then check that the subtitle, back cover, and retail description do not repeat the same opening or wording. Ask up to 3 clarifying questions only if a required input is missing.
Fill in
| Placeholder | What to enter | Example |
|---|---|---|
| [BOOK TITLE] | Enter the title exactly as it will appear on the book. | The Monday Handoff |
| [GENRE AND FORMAT] | State the genre and format, such as business nonfiction paperback or literary mystery. | Business nonfiction paperback. |
| [TARGET READER] | Describe the intended reader and what they want from this book. | New operations managers whose teams lose work between shifts. |

How to use
- Paste a synopsis detailed enough to show the actual promise and contents.
- Choose comparables from the reader's shelf, not simply books you admire.
- Check each line against the manuscript, especially outcomes and author claims.
- Follow up with: "Give me three versions for bookstore browsing: practical, authoritative, and warm, without adding claims."
Variations
Fiction jacket copy
Use for a novel where premise and stakes must hook without spoilers.
Write 120-160 words of back-cover copy for [NOVEL TITLE], a [GENRE] novel. Use only [PLOT NOTES], [PROTAGONIST], and [TONE]. Establish the protagonist's normal world, the inciting disruption, the central conflict, and what is at stake. Reveal no twists after [SPOILER BOUNDARY]. Give three opening-hook options and one final version. Avoid review-style praise and invented comparisons. Check that all named characters, places, and events occur in the notes. Ask up to 3 questions only if inputs are missing.
Nonfiction subtitle
Use when the title exists but the book's value is unclear at a glance.
Generate 15 subtitle options for [BOOK TITLE], a book about [SUBJECT] for [TARGET READER]. The manuscript teaches [SPECIFIC APPROACH] and can honestly promise [SUPPORTED OUTCOME]. Mix benefit-led, problem-led, and method-led options, each 5-14 words. Avoid claims of guaranteed results, jargon, and words already in the title. Rank the top five with one sentence each explaining their shelf clarity and fit with [MARKET POSITION]. Ask up to 3 questions only if required inputs are missing.
Book proposal copy
Use for a proposal rather than finished cover copy.
Draft the positioning section for a book proposal for [WORKING TITLE]. Use [AUDIENCE], [PROBLEM], [BOOK APPROACH], and [AUTHOR PLATFORM]. Output a 150-word overview, a 75-word reader profile, and five comparable-title entries that explain differentiation without claiming sales data unless supplied. State what readers will learn and what the book will not cover. Flag platform or market claims that need evidence. Ask up to 3 questions only if necessary.
Tips
- A subtitle should reduce ambiguity created by the title; do not make it a second title.
- Back-cover copy sells the reading experience, while retail copy should carry search-friendly specifics without becoming a keyword list.
- For nonfiction, audit promises against chapter-level material so the cover does not market a book that has not been written.
- For fiction, identify the spoil-safe boundary before drafting; many otherwise strong blurbs reveal the turn that readers should discover.
FAQ
Should a book cover mention comparable titles?
Usually not in the final copy unless a publisher has approved the comparison. Use comparables to guide tone and shelf position.
Can AI write endorsements?
It can draft a request for an endorser, but it should not fabricate endorsement quotes or names.
How long should back-cover copy be?
Around 150-190 words is often enough for a paperback, but the actual layout and publisher specifications control.
