How to Make Money with AI Coloring Books on Amazon KDP (Using Free Tools)
If you’ve ever wondered how to make money online, AI Coloring Books on Amazon KDP are one of the easiest ways to start. With free AI tools, you can create high-quality coloring books, publish them quickly, and begin earning passive income — all without expensive software or advanced design skills.
This method is beginner-friendly, requires no design skills, and can open the door to real passive income opportunities.
Why AI Coloring Books on Amazon KDP Are a Great Niche?
Coloring books have been one of the most consistent sellers on Amazon KDP. Unlike complicated niches, they’re evergreen, appealing to kids, adults, seniors, and even stress-relief seekers.
But here’s the catch: popular niches like “bold and easy coloring books” are flooded with thousands of competitors. If you want to succeed, you’ll need to niche down into smaller, less competitive categories.
For example, instead of publishing another generic “bold and easy” book, you could create a “Bold and Easy Country Coloring Book.” With fewer than 120 competing titles, this niche still shows solid demand, giving beginners a much better chance at ranking and making sales.
Real Earning Potential on Amazon KDP
Let’s talk numbers.
One “cozy country farm” coloring book currently sells at $9.99 with around 40 pages. Based on its Best Seller Rank (33,000), it’s estimated to bring in about $850 per month in royalties.
Of course, not every book will perform at that level. Some may earn less, some may earn more — but with the right niche and consistent quality, these books can generate steady, hands-off income.
The Free AI Tool You’ll Use
Most AI image generators (like MidJourney or Firefly) either charge monthly fees, limit your credits, or have confusing licensing rules.
But Gen Tube changes the game:
✅ 100% Free
✅ Unlimited image generation
✅ Commercial rights included
✅ Works on desktop and mobile
All you need to do is type in prompts like:
“Tractor in a field, bold thick lines, minimal background”
And instantly, you’ll have a coloring page that’s ready to use.
Pro tip: To save time, you can generate a list of prompts with ChatGPT (e.g., “50 farm-themed coloring book prompts”). Then paste them one by one into Gen Tube, refine the designs, and download.
How to Assemble Your Coloring Book
Once you’ve created 30–40 coloring pages, it’s time to put your book together:
Open Canva (free account works just fine).
Set custom size: 8.5” x 8.5” (standard for coloring books).
Add a “This book belongs to” page.
Insert each coloring page, alternating with a blank page (so ink doesn’t bleed through).
Save as PDF Print and upload to Amazon KDP.
That’s it — you now have a publish-ready coloring book created entirely with free tools.
How Much Can You Really Earn?
Here’s a quick calculation:
Price per book: $9.99
Royalty per sale: $3.15
Estimated sales: 270 per month (based on similar books)
👉 Monthly income: $850+ from one book.
Even if your book earns half of that, imagine having 5–10 books published — the potential adds up fast.
