One of the best ways to create passive income online is to write a digital ebook and sell it. The problem? Most people procrastinate for months because writing feels overwhelming.
That’s where Claude comes in.
Claude is an AI assistant made by Anthropic. In my experience, it produces some of the cleanest, most readable writing of any AI tool available right now. And it’s incredibly easy to use for creating full ebooks from scratch.
In this guide, I’ll walk you through the exact process to use Claude to write your first ebook — from idea to finished product.
Before You Start: Pick a Topic That Sells
The best ebook topics solve a specific problem for a specific person.
Ask yourself: What do people frequently ask me about? What did I learn that took me a long time to figure out that I could teach someone else faster?
Good ebook topics follow this formula: [Specific Result] for [Specific Person] in [Specific Timeframe]
Examples:
- “How to Plan 30 Days of Instagram Content in One Weekend (Using AI)”
- “The Beginner’s Guide to Setting Up Your Digital Product Shop in a Day”
- “7 Simple Claude Prompts That Write Your Captions, Emails, and Product Descriptions”
Step 1: Create Your Outline With Claude
Open Claude and paste this prompt:
“I want to write a beginner-friendly ebook about [your topic]. My target reader is [describe your audience]. Please create a detailed outline with 6-8 chapters, each with 3-5 subheadings. The tone should be warm, clear, and encouraging.”
Review the outline it gives you. Delete anything that doesn’t fit. Add chapters you want that it missed. This outline becomes the skeleton of your entire book.
Step 2: Write Each Chapter Section by Section
Here is the most important thing to know: don’t ask Claude to write the whole book at once. Write it section by section. This gives you better quality and more control.
For each section, use this prompt:
“Write a 300-400 word section for my ebook on [your topic]. The section title is [section title]. The key points to cover are: [list 2-3 points]. Write in a warm, beginner-friendly, first-person tone as if AI Creator Income Lab is explaining this to a friend.”
Why include “as if AI Creator Income Lab is explaining this to a friend”? Because it gives Claude a persona and tone to follow. You can swap that out for your own name and style.
Step 3: Add Your Personal Voice
This is the step most people skip — and it’s why a lot of AI ebooks feel generic.
After Claude writes each section, go through it and:
- Add a personal story or example from your own life
- Change any words that don’t sound like you
- Add a line here and there that feels authentic to your personality
You’re not rewriting the whole thing. You’re just adding the human layer on top of the AI draft.
Step 4: Write Your Introduction and Conclusion
Ask Claude to write these last, after the chapters are done:
“Based on this ebook outline about [topic], write an engaging introduction that hooks the reader, tells them what they will learn, and encourages them to keep reading. Write it in a warm, conversational tone.”
And for the conclusion:
“Write a motivating conclusion for my ebook. Summarize the key takeaways, encourage the reader to take action, and let them know about other resources available at [your website].”
Step 5: Format and Design
You don’t need to be a designer. Here are your easiest options:
Canva — Free. Use the “Document” or “Ebook” templates. Copy and paste your Claude-written text into each page.
Google Docs — Write it all in one doc, set the formatting (fonts, headers, line spacing), then download it as a PDF.
Microsoft Word — Same idea. Use a clean template and export as PDF.
Keep your design simple. Clean fonts, plenty of white space, and a consistent color palette. You don’t need it to look like a New York Times bestseller. You need it to be easy to read and solve the problem you promised.
Step 6: Price It and Sell It
For your first ebook, I recommend pricing it between $17 and $47 depending on the depth of the content.
Upload it to Gumroad, Payhip, or Lemon Squeezy. These platforms handle payment processing and file delivery automatically. You can be set up and ready to sell within a couple of hours.
Then mention it in your social media content, link to it in your bio, and email it to your list.
How Long Does This Take?
With Claude, you can write a solid 20-30 page ebook in a single weekend. Here’s a rough timeline:
- Friday night: Create your outline and write 2-3 chapters
- Saturday: Write the remaining chapters
- Sunday: Write intro and conclusion, edit, format in Canva, upload to Gumroad
That’s it. A complete digital product you can sell forever.
