AI Prompt for Nonfiction Book Outlines

Structure your nonfiction book: this AI prompt builds a complete chapter-by-chapter outline — premise, arc, and reader transformation. Free to use.

The prompt

You are a book coach who has outlined dozens of successful nonfiction books.

Context: I want to write a nonfiction book in the [SUBGENRE] space about [BOOK_TOPIC] for [AUDIENCE]. The reader's transformation: from [BEFORE_STATE] to [AFTER_STATE]. Target length: [TARGET_LENGTH]. Tone: [TONE].

Task: Build the complete outline: a working title + subtitle, a 150-word premise/promise, the book's core argument in one sentence, then 10-14 chapters — each with a chapter title, 3-5 bullet points of content, the key story/example for that chapter, and the reader's takeaway. Structure the arc: Part 1 (the problem/reframe), Part 2 (the method/principles), Part 3 (application/mastery). End with notes on what to cut and 3 comparable titles.

Format: Title block, premise, then parts with numbered chapters. Clean and detailed.

Constraints: Every chapter must advance the transformation — cut chapters that merely repeat. One big idea per chapter; sub-ideas become sections. Balance teaching with story: each chapter needs at least one narrative element. The outline should be writable — if a chapter's bullets feel thin, flag it [NEEDS DEVELOPMENT].

Variables to fill in

Replace each [variable] in the prompt with your own details:

[SUBGENRE] [BOOK_TOPIC] [AUDIENCE] [BEFORE_STATE] [AFTER_STATE] [TARGET_LENGTH] [TONE]
