An AI Non-Fiction Book Writer That Lets You Decide How the Argument Is Made
A non-fiction book is an argument with a shape. Most tools skip that part and go straight to prose, which is why the chapters come out interchangeable. Here you choose the structure the book uses to make its case, the template every chapter follows, and whether the AI is allowed to depart from it — before a single chapter is written.
Three decisions you make first
Your first book outline and your first chapter are free on a new account, which comes with 100 credits. Chapter outlines cost 3 credits each; a full chapter costs 15.

Three book structures and three chapter templates, generated from your topic and audience. You pick one of each, then decide whether the AI sticks to the template or varies it.

The Three Decisions That Shape the Book
These are made on the Book Details and Book Structure steps, before the outline exists. Nothing is written until you have settled them, and you can regenerate any of them with an instruction of your own.
On the details step you set Content Structure: the method the book uses to convince. Step-by-step, case-study based, research-backed, problem-solution, chronological, thematic, comparative, framework-based, workbook style, reference manual, narrative non-fiction and a dozen more. Alongside it you set tone — authoritative, conversational, evidence-based, scholarly, empathetic — and Content Techniques, which are the elements the chapters are allowed to use: real-world examples, actionable exercises, key takeaways, checklists, myth busting, reflection questions, statistics and data.
You also describe the reader in your own words, and the AI adjusts vocabulary, complexity and examples to them rather than writing for everyone.
The Book Structure step generates three whole-book structures and three chapter templates, built from your topic, genre, audience and chapter count. A book structure is a set of named parts with a stated purpose and a chapter range. A chapter template is the internal order of a chapter — hook, core concept, research backing, real examples, common mistakes, your turn, key takeaways — with the chapter extras each template carries. You read all three of each and choose.
Not the shape you had in mind? Regenerate with an instruction: include exercises per chapter, organize chronologically, add practical tips.
One toggle, and it matters more than it looks. Left on, the AI adds variety to the chapter structure as it builds the outline, so chapter four does not read as a refill of chapter three's container. Turned off, it follows the template exactly, chapter after chapter — which is what a workbook, a reference manual or a course companion actually needs.
The toggle sits on the same screen as the templates, so you choose consistency or variety with the template in front of you.
How a Non-Fiction Book Gets Written Here
Six steps in order. Every step is saved as you go, so a book can sit for a week between the outline and the first chapter and be exactly where you left it.
Details
Title, description, genres, and the reader you are writing for. Then tone, Content Structure and Content Techniques. You can generate all of it from your description and edit what comes back, or fill each field yourself. There is also a writing style field where you paste six to ten paragraphs of your own prose for the AI to match.
Reference files
Upload the research the book stands on — PDF, DOCX, DOC, TXT, MD, EPUB or RTF, up to ten files and 100,000 words in total. The first file is free, each one after that costs 10 credits. Turn on Include Citations and the chapters cite and reference the material you uploaded instead of asserting things unsourced.
Structure
Three book structures and three chapter templates are generated together. You select one of each, look at the chapter extras the template carries, and set the variations toggle. This is the step that decides what every later chapter will look like.
Outline
The outline is built against the structure you chose, twenty chapters at a time, at 3 credits per chapter. Each entry gets a title, a target word count between 200 and 5,000, a structured outline, its chapter metadata and the excerpts from your reference files that belong to it. Edit one chapter with an instruction, or edit them all — with an option to adapt the other chapters so the change stays consistent.
Chapters
Chapters are written one at a time against their outline, the book structure and the chapter template. 15 credits with Gemini, 20 with Grok, 30 with Claude Sonnet, which is the model that supports citations. The first chapter you generate in a book is free.
Publish
Cover, blurb, categories, keywords, author bio and copyright page, then export. Formatted PDF, EPUB and print-ready files are on the Pro plan; DOCX export comes with any paid plan.
Why a Template Beats a Longer Prompt
You can ask a chat model for a chapter and get a good one. Ask it for twenty and you get twenty chapters that each solved the problem their own way — a book with no spine. The structure step exists because consistency across a whole manuscript is a structural property, not a prose property, and it has to be decided once, in advance, in a form the outline and every chapter can be checked against.
Sections with a stated purpose
Each part of the book structure carries a purpose line and a chapter range, so you can see what a section is for before any of it is written.
The same internal order
The chapter template fixes the order inside a chapter. A reader who learns the rhythm in chapter two can rely on it in chapter fourteen.
Chapter extras, declared up front
Exercises, action steps, real-life cases, reflection questions, key takeaways — the template says which ones the book uses, so they appear everywhere or nowhere.
Variation as a choice
Whether chapters may diverge from the template is a toggle you set, not something the model decides differently each time it runs.
What the Non-Fiction Path Gives You That the Fiction Path Does Not
Non-fiction is a separate book type here, with its own details step, its own structure step, its own outline and its own chapter writer.
Reference Files, Not Guesswork
Ten files, 100,000 words total, in PDF, DOCX, DOC, TXT, MD, EPUB or RTF. The material is parsed once and the relevant excerpts are attached to the individual chapter outlines they belong to, so a chapter is written against the sources for that chapter rather than a vague memory of everything you uploaded.
Citations You Switch On
Include Citations is a setting on the book. With it on, the chapters cite and reference the material from your uploaded files. Claude Sonnet is the model that supports citations; Gemini is the one that follows instructions most closely. You choose per book.
Twenty Structure Choices, Not One House Style
Content Structure covers step-by-step, case-study based, research-backed, story-driven, Q&A, listicle, problem-solution, chronological, thematic, comparative, interview-based, personal anecdotes, framework-based, exercise-driven, workbook, journalistic, academic, narrative non-fiction, how-to guide and reference manual.
Word Counts You Set Per Chapter
Every chapter in the outline carries its own target between 200 and 5,000 words. A short framing chapter and a long case-study chapter can live in the same book without you fighting the tool for it.
Edit the Outline With Instructions
Rewrite a single chapter outline, or all of them at once, by describing the change. There is a toggle to adapt the other chapters to what you just changed, so a structural edit does not leave the rest of the book contradicting it.
Long Books Handled in Batches
Outlines generate twenty chapters at a time and continue from where they stopped, so a forty-chapter reference book is a matter of pressing continue rather than finding a workaround.
The Non-Fiction Books This Suits
Books where the shape of the argument is the thing the reader is paying for.
Self-Help and Practical Guides
A framework-based structure with an exercise-driven chapter template, variations off, so every chapter ends with the same kind of work for the reader. Consistency is the product.
Business and Professional Books
Case-study based or problem-solution, with real-world examples and statistics turned on as techniques, and your own research uploaded as reference files with citations enabled.
Academic and Research-Backed Writing
A thematic or comparative structure, a scholarly tone, Claude Sonnet for citations, and the sources attached chapter by chapter rather than pasted into a prompt.
Memoir and Narrative Non-Fiction
Chronological or narrative structure with variations left on, so chapters are allowed to breathe differently — because a life does not repeat the same shape twenty times.
What a Non-Fiction Book Costs to Write
Credits come from your plan or a one-time pack. Planning is cheap on purpose; the writing is where the credits go.
Planning the book
Book details, tone, structure choice, chapter template and the variations toggle cost nothing. The outline is 3 credits per chapter. A twenty-chapter book is planned end to end for 60 credits, and a new account starts with 100.
