From the makers of Designrr - trusted by 450,000+ authors worldwide.
As the largest eBook creation company in the world, we've seen how it goes for most authors.
You've got something worth saying - real knowledge, the kind people would pay for. So you pick your topic, and you pour months of nights and weekends into it: the writing, the cover, the formatting, the price, the categories - guessing at every step, but telling yourself it'll be worth it.
Then you hit publish… and you wait.
A handful of sales trickle in - your sister, a friend, someone from work. And then… nothing. Days go by. The dashboard sits at zero. Amazon never picks it up, never shows it to a single real buyer - and the cruelest part is nobody ever tells you why. Just silence, where all that hope used to be.
Here's the truth almost no one says out loud: it was never your writing.

Not because those books are bad. Because they were published blind - the authors had no way of knowing if a single person wanted the book before they gave it months of their life.
Amazon decides which books to promote based on dozens of demand signals - real-time search volume, sales velocity, how many reviews the competition has, how deep the category runs, where the pricing lands, and a dozen more. Miss them, and you stay invisible no matter how good your book is. Nail them, and Amazon starts selling your book for you.
The problem? No author can track all of them. That's what BookSignal does. It reads every demand signal Amazon watches, weighs them the way the algorithm does, and hands you one simple verdict on any idea: GO or SKIP.
So instead of guessing and praying, you get the one edge almost no author has: you can actually read the signals Amazon uses to decide who gets promoted - and who gets buried. You publish with all of them baked in, and Amazon starts selling your book for you, ahead of everyone still hoping.
I'm Paul Clifford, founder of Designrr - the largest eBook creation platform in the world, trusted by over 450,000 authors, including people at Amazon, LinkedIn, Harvard and Meta.
Over the years we've helped tens of thousands of people turn what they know into published books. And we kept watching the same heartbreaking thing happen: talented people writing genuinely good books that went nowhere - because they'd bet months of work on a topic nobody was actually searching for.
So we spent the last year building the tool we always wished our authors had - one that reads the demand signals hiding in Amazon's own data and answers the one question that decides whether a book makes money: will people actually buy this, before you write it?
That's BookSignal. It's the first new app we've released in eight years - and it's the one I'm proudest of.
Same you. Same effort. Completely different result - because this time you're not guessing. You're reading the signals.
Imagine publishing a book you already know will sell - before you write a single page. Not hoping. Knowing. A book Amazon puts in front of buyers for you, that delivers real value to your readers and pays you month after month while you sleep - no marketing budget, no late nights slaving over a manuscript and praying it sells the day it drops.
BookSignal kills the hunch. It's an AI Amazon-intelligence engine that plugs straight into Amazon's live data - the real search volume, rankings, and sales moving through your niche right now - and reads the market back to you in plain English. Think X-ray vision into a market every other author walks into blind.
Say you want to write on anger management. Type it in. BookSignal reads the market data and tells you straight: too broad, too much competition - skip it. The page-one books have thousands of reviews; you'd be invisible for years.
But it doesn't strand you at "no." It surfaces the ways in - the profitable angles hiding inside that broad topic:
Three green-lit GOs from one idea you almost wrote blind - and together, a $2K-a-month slice of a market you'd have been invisible in. Then it hands you everything to win each one:
No rough estimates. No inflated numbers to get you excited. Just the truth, and the plan - before you write a word. And it works in your niche: with hundreds of millions of buyers shopping Amazon every month, there's proven demand for almost any topic you can imagine.
Picture two authors publishing the same week. The first writes a solid book on "meditation," picks a title that sounds nice, guesses a category, prices it on a hunch, and waits. Amazon has no reason to push it - so it doesn't. Silence.
The second uses BookSignal: same effort, same quality - but she's writing "meditation for new moms," a term real buyers actually search, she's in a category she can rank #1 in, and she's priced where the data says it sells.
So Amazon sees a winner: within weeks it slots her under a rival's bestseller, drops her into "customers also bought," and pushes her to its own buyer list so she starts making $100/day from book sales without spending a dime. Same effort - wildly different outcome. One published on a hunch and vanished. The other spoke the algorithm's language, and Amazon sold it for her.
Answer a few quick questions about your interests and expertise - or skip ahead and type in a topic you've already got. Either way, BookSignal hands you a list of proven, in-demand book ideas to choose from, each with a demand score beside it. Pick the one that catches your eye.
Takes 30 seconds. No idea where to start? Even better - BookSignal finds the angles for you.
Click any idea and BookSignal drills in - checking real Amazon demand and the books you'd be up against, then handing you a clear verdict: how much it can realistically earn, and whether you can actually win the niche.
This is the whole game. You find out if there's money there before you spend a single day writing - and if it's a SKIP, BookSignal points you to a nearby pocket where there is.
Get the exact books to write, the proven keywords and categories to use, and a step-by-step publishing plan. Your book goes live already optimized for Amazon to promote it for you - no SEO rabbit holes, no guesswork, no figuring it out alone.

Say you're into wellness and business but have no clue what to write. Here's how BookSignal reads the demand signals in your niche and takes you from "no idea" to "ready to publish" in five minutes - tool by tool, before you write a word.
Answer a few quick questions about what you're into, and Niche Finder hands you proven topics with real Amazon demand - "mindfulness for entrepreneurs," "stress management for founders," "morning routines for busy professionals" - each with a demand score beside it. You finally publish what you love and make money doing it.
Click a topic and Topic Explorer pulls the books ranking for it right now, then gives it to you straight. "Mindfulness for entrepreneurs"? SKIP - page one has thousands of reviews; you'd be invisible for years. But it shows you the way in: "mindfulness for first-time founders" - strong demand, few real competitors, a realistic income. GO. Now you know it's worth writing - before you spend a day on it.
Pick your winner and Book Ideas hands you a whole list of titles to publish in that niche - like "The 5-Minute Founder Reset" - each with its own proven keywords and the exact category to rank in. Instead of gambling on one title, you build several - each quietly banking income, month after month.
Every keyword and category is pulled from live Amazon data - the exact terms you can actually rank for, and the categories where it's easiest to grab a #1 Best Seller badge. Drop them into your title and description and you're speaking the algorithm's language. No SEO rabbit holes, no jargon - just copy, paste, done.
Don't know how to price it, title it, or what to do after upload? Just ask. It's trained to give you exact, step-by-step answers for every part of getting a book live - like a seasoned publisher on call 24/7.
Drop in any book's Amazon rank and instantly see how many copies a day it's selling and what it's earning. Confirm a niche has real money in it - and prove the numbers with your own eyes before you commit.
Found a book that's crushing it in your niche? Paste its Amazon link and Bestseller Spy reads the demand signals behind it - the exact keywords that book ranks for, with real monthly search volume, its rank on each one, and the categories it's winning in.

Five minutes in: you've got books you know will sell, the keywords to get them found, and a plan to publish - and you haven't written a word yet.
BookSignal doesn't just hand you a single idea - it hands you a whole list of winnable books in your niche, each with proven demand and real profit potential. So instead of betting everything on one title and hoping, you publish several - each one validated against the same demand signals, each one Amazon promotes for you:
It's a steady, reliable - and most importantly, REALISTIC - income that grows every time you add another book to your shelf. $5K isn't a miracle, it's just a matter of how many you publish. And with the eBook creation bonus, banging out high-quality books has never been faster.
"Hit #1 bestseller in two ultra-competitive categories within two days of release. None of my four previous books had ever sold."
