Free AI Book Outline Generator

Describe your book idea and get a chapter-by-chapter plan: 8–15 chapter titles, each with a one-line summary. It's an AI suggestion to shape and rearrange — then, if you like it, write the whole book from it.

Free, no account needed — a few runs a day. AI suggestions: edit them and make them yours.

Why outline at all?

An outline is a map, not a cage. It shows you where the book is going so you can write each chapter knowing what it has to do — and spot structural problems (a sagging middle, a missing step, a climax that comes too early) before you've written 50,000 words around them. Most stalled manuscripts stall because the writer didn't know what came next.

How to outline a novel

Most commercial fiction follows a recognisable shape, whatever name you give it:

  1. Setup — the protagonist's ordinary world and what they want.
  2. Inciting incident — something that disrupts it and can't be ignored.
  3. Rising complications — attempts, failures and higher stakes.
  4. Midpoint turn — a revelation that changes what the story is about.
  5. Crisis — the lowest point, where the old approach fails completely.
  6. Climax and resolution — the final confrontation and the new normal.

Each chapter should change something: a new piece of information, a decision, a reversal. If you can't say what changes in a chapter's one-line summary, it probably needs merging with its neighbour.

How to outline a non-fiction book

Non-fiction outlines follow the reader's journey from problem to result. A reliable pattern: open with why the problem matters, give the core idea or framework, then devote a chapter to each step or principle, and close with how to keep going. Every chapter title should promise one clear takeaway — readers skim contents pages before buying.

Getting a better outline from the generator

  • Include the ending (or the result for non-fiction). The AI plans backwards from it much better than it guesses.
  • Mention the protagonist's flaw or the reader's biggest objection — it gives the middle chapters something to work on.
  • Choose the chapter count deliberately. 8–10 for short guides and novellas, 12–15 for full-length books (split them later).
  • Generate two versions and combine the strongest chapters.

Common outlining mistakes

  • Too much detail too early. A 30-page outline can drain the fun from drafting. One line per chapter is enough to start.
  • Chapters that repeat the same beat — two chapters of "she investigates and finds nothing" is one chapter.
  • No escalation. Stakes should rise chapter by chapter, not stay flat.
  • Treating the outline as final. It will change once you write; that's the point of having it.

Frequently asked questions

How many chapters should a book have?+

There is no fixed number. Many novels have 20–40 chapters and many non-fiction books 8–15. This generator plans 8–15 high-level chapters, which you can split further as you write.

Do I need an outline to write a book?+

No — some writers discover the story as they go. But even 'pantsers' often outline after a first draft to fix structure. A one-line-per-chapter outline is the lightest useful version.

Can I use the AI outline for my book?+

Yes. It's a suggestion generated for your idea, so rearrange, cut and rename freely. Expect to change it: the AI doesn't know your characters or expertise the way you do.

Is the outline generator free?+

Yes, a few runs a day without an account. In Inkora you get a full book plan — characters, themes, chapter beats — and can then write the chapters.

What happens when I click "Write this book"?+

It opens a new book in Inkora with your book type and genre selected (you'll be asked to sign up first if you haven't). Your idea is also saved in this browser so you don't lose it.
