A cozy mystery from idea to KDP

Illustrative example. This walkthrough shows how the workflow fits this kind of book. The author and book are fictional; no results are claimed.

Dana is a retired school librarian who has read cozy mysteries for decades and wants to publish her first one on Amazon KDP, as an ebook and a paperback. Her book, Crumbs at Low Tide, follows a bakery owner in a small coastal town who has to clear her best friend of murder. Here’s how she could take it through AIBookWriter. Before any paid action, the app shows its price, her balance and the balance after.

Concept and basics

She chooses Fiction and describes her idea in a paragraph: the bakery, the poisoned lemon tart, the best friend under suspicion, the cat. The app fills in the basics from it for free, and on Basics she edits them:

• Title and author name: Crumbs at Low Tide, under her pen name
• Language: English
• Main genre and subgenres: Mystery, with Cozy and Amateur sleuth
• Number of chapters: 24

Details and style

This step sets the voice:

• Target audience: Adult
• Point of view and tense: first person, past tense, so readers solve the case alongside her sleuth
• Tone: Cozy, Humorous and Warm
• Writing style: Plain and clear, Character-driven
• Story elements and selling points: Mystery to solve, Animal companion, Clean / no explicit content, Series starter
• Mature content: left off, its default
• Writing sample: about 12,000 characters from a short story she wrote, well within the 20,000-character limit, so chapters follow her rhythm and humor

Characters

She asks for a cast of six with Generate with AI, which doesn’t use credits, then reworks it by hand. Each character has a name, role, appearance, background, personality, motivation, conflicts, stakes, an arc and a note on how they speak. She spends the most time on speech, which separates a gruff harbor master from a gossiping café regular. For bigger changes she types an instruction, such as “make the detective drier and less hostile,” and the character is revised.

Outline

On the Outline step she keeps 24 chapters, picks the Three-Act Structure and generates. As the first outline on her account, it’s free; after that, outlines cost 3 credits per chapter, which would be 72 credits here. Every chapter arrives as a card with a title, a summary, beats, an ending hook, a location, the characters in it and a target word count. Dana sets about 3,000 words per chapter, moves the second clue two chapters later and adds a red herring at the farmers’ market.

Writing the chapters

Dana is still on the Free plan, which comes with 100 credits at sign-up and lets AI write chapter 1. She picks the Balanced tier, 20 credits a chapter (Swift is 15 and Literary 30), and generates chapter 1. The draft streams in, and she reads it against her own story. The jokes come too often, so she adds “keep the humor dry and occasional” as direction for the next draft.

Happy with the voice, she moves to the Pro plan: $30 a month billed yearly, or $37 monthly, with 5,000 credits a month. She’ll need Pro anyway for print-ready PDF and EPUB formatting and a book page. Then she uses the batch option to write the remaining 23 chapters: 460 credits, reserved up front, and if she stopped part-way she’d pay only for the chapters finished.

New AI drafts never replace her text. When she regenerates two chapters that fell flat, each new draft appears next to her version for comparison, and every save goes into the version history. To fix a passage, she selects it, describes the change and accepts or rejects the suggestion. Each AI chat edit costs 5 credits and applies only to the passage it was made for.

Review

With about 72,000 words drafted, she runs the whole-book review: 15 credits per 1,000 words, or about 1,080 credits, charged once for the book. The report gives an overall score, an editorial letter, chapter-by-chapter pacing notes and line edits she accepts or rejects one at a time. Suppose the letter says the middle sags and the culprit is easy to spot by chapter 12. She tightens chapters 9 to 14, strengthens the red herring and runs the review again, which is free.

Metadata and cover

On Metadata & cover she starts from the AI’s suggestions and edits them: a blurb, seven backend keywords, up to three store categories, and the series name with this as book 1. She leaves the ebook ISBN blank, since Kindle doesn’t require one, and plans to take KDP’s free ISBN for the paperback. An AI cover costs 30 credits; she generates two and checks the lettering of the title and her name on the one she keeps.

Format and export

She chooses a 5.5" × 8.5" trim size and a theme, runs the preflight checks and exports a print-ready PDF and an EPUB. The spine width for the full-wrap paperback cover is calculated from her page count. Formatting costs 200 credits once for the book, so when she fixes a typo later, the re-export is free.

Publish and distribution

On Publish, Dana sets up her author page and a book page with free sample chapters and an email sign-up for readers who want more. Because she’s considering KDP Select for the ebook, she keeps the free sample within the program’s limit on content shared elsewhere. On Distribution she drafts launch social posts, a welcome email sequence, a press kit for her local paper and review requests for her ARC team, all built from the book.

Then she uploads the files to KDP herself, orders a proof copy and sets her prices with the free KDP Royalty Calculator.
