It Uses “Next-Gen” A.I. Technology To Automate How Creators Build, Publish & Scale Their Book-Based Online Income!

What if you could publish a bestselling book in 4 minutes – without writing a single word yourself?
 
Right now, REAL PEOPLE like you and me are quietly earning ongoing passive income by publishing non-fiction and low-content books on Amazon.
 
AND, they’re doing it:
 
✅  WITHOUT running ads
✅  WITHOUT building funnels
✅  WITHOUT creating content
✅  WITHOUT becoming an “influencer”
 
 
And that’s because Amazon’s amazing KDP program (Kindle Direct Publishing) makes it easy for ANYONE to publish a book AND get traffic and sales from your books!
 
And right now, there’s a fortune being made in something called “MID CONTENT BOOKS”…
 
These are hot-selling paperback books like Crossword Puzzle Books, Word Search Books and Coloring Books.
 

Do you want THE HARD WAY, or THE EASY WAY?

Book Ninja is CRAZY EASY!
 
Dave Espino here – I’ve made some great passive income with mid-content books, but before Book Ninja, we’ve had to do it THE HARD WAY…
 
👉  You had to do lots of research into what the hot selling book niches were…
 
👉  You had to create each individual coloring page, one-by-one by using AI image generators (that were not always perfect)
 
👉  And then you had to compile those pages into a book… (or pay someone on Fiverr to do it for you) 
 
👉  And then, you had to create a great book cover (or pay someone on Fiverr to do it for you)
 
👉  And FINALLY, you’d be able to upload your book to Amazon…
 
But here’s the thing…
 
👉  YOU STILL HAD NO IDEA IF THAT BOOK WOULD SELL OR NOT.
 
Even though I did SOME research before creating my books, it wasn’t ENOUGH to tell me 100% that it would sell.
 
Lucky for me, the huge amount of time I spent researching books paid off and I’ve been able to do quite will with my Amazon KDP business.

“Above is the 4-step process to create amazing projects with Book Ninja for your business & marketing needs. Now let’s come down to the next section of Book Ninja Review.”

This is from my own Amazon KDP stats for January 2026
