First Book ai is an AI-powered co-authoring platform that helps professionals turn their expertise into a structured nonfiction book. Instead of generating generic text, it co-authors with you, capturing your voice and knowledge.

How It Works

  1. Share Your Story: Complete a questionnaire about your topic, audience, tone, and key anecdotes.
  2. Review Your Outline: The platform generates an 8-chapter outline with strategic intent. You can edit and rearrange it.
  3. Write Chapter by Chapter: Each chapter is written in your voice. You review, edit inline, request rewrites, or approve. You control the depth per chapter (2,000 to 8,000 words).

Key Features

  • Structured Outline: 8 chapters, each with 3 subchapters, strategically sequenced.
  • Your Voice: A style profile is built from your writing sample and tone preferences.
  • Chapter Control: Approve, edit, or regenerate each chapter.
  • Depth Selection: Choose chapter length from brief to deep dive.
  • AI-Generated Cover: Get a unique cover design.
  • Export Formats: Download as Word, Markdown, EPUB, or PDF.
  • Credits System: Pay once per book credit, no subscription.

Who It's For

Professionals with expertise to share: coaches, consultants, business leaders, and aspiring authors who struggle with writer's block or lack of time.

The platform is trusted by over 2,400 authors, with 10,000+ books created, and holds a 4.2-star rating on AppSumo.
