First Book ai

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).
