Paste a word list. Three minutes later you have a print-ready interior, a full-wrap KDP cover, and an Amazon listing — and a QR code on every page that says the word, spells it, and uses it in a sentence in a real voice. The child can finally use the book without an adult sitting next to them.
That page on the left came out of EchoBooks AI. The phone on the right is not a picture — it's the actual page loading live, right now, from the QR code printed on it.
A real page, straight out of the app — nothing retouched.
This is what your buyer's four-year-old sees and hears.
No app. No login. No account. Just a camera.
It's a quarter past eleven at night.
You have Canva open. You have twenty-six pages to lay out and you're on page four. The tracing font looked fine on screen and printed like a grey smudge. The clipart you found doesn't match the clipart on page two. You still have to write the description, guess seven keywords, and design a cover with a spine you don't know how to calculate.
And when it's finally done — after two evenings you won't get back — it lands on Amazon next to forty thousand books that look exactly like it, all priced at $6.99, all fighting over the same buyer.
You didn't lose because your book was bad. You lost because there was no reason to pick yours.
I want to show you a reason. It costs you nothing extra to add, no competitor in the category has it, and a parent can see it in the "Look Inside" preview in about two seconds.
Your book talks. Theirs doesn't.
Forty words means forty pages, each with tracing lines, letter boxes, a sentence, and a puzzle — laid out by hand, one at a time, matching perfectly.
Grey "ghost" tracing text vanishes on paper. Images under 300 DPI get rejected. Margins that ignore the gutter make the inner column unreadable.
Full wrap, bleed, and a spine width that changes with your page count. Get it wrong and KDP bounces the file back at you.
After all that work your book is one more silent worksheet book on a shelf of silent worksheet books, competing only on price.
Here's what actually happens after somebody buys a sight-words workbook.
Mum opens it with her four-year-old. Page one says "Read the word." And the four-year-old can't — that's the entire reason the book was bought.
So Mum reads it to her. Fine on Tuesday. On Thursday she's making dinner. By Sunday the book is under the sofa, and three weeks later the review says "my child couldn't use this on their own."
Put a QR code on that page and the sentence changes. The child scans it herself and hears:
Then she does the eight activities printed on the same page. The adult has been removed from the loop. The book gets used on Thursday. It gets used on Sunday. And the review says something very different.
That is the whole idea, and it is the reason your book is worth more than the $6.99 one beside it.
Dolch Pre-Primer, Dolch Primer, or Spelling Grade 1. The words load themselves — you don't type anything.
EchoBooks writes the teaching script for every single word. Don't like a line? Rewrite it. Want to hear it first? Press play.
Interior PDF, full-wrap cover PDF, and an Amazon listing pack. The audio goes live at the same moment — the QR codes work before you've uploaded anything.

That's the actual output. Nothing else to buy, nothing else to install.
I've bought "60-page" workbooks that were twelve pages repeated five times. This is not that. Hover or tap any page to see it straight.
The word, huge, with a line-art picture clue for a child who can't read it yet.
Hollow outline letters — fine motor practice that doubles as quiet time.
Empty letter boxes plus the scrambled letters underneath.
Two difficulty levels of real dotted letter paths — not grey text that disappears in print.
Ruled practice lines with a dashed mid-line, school handwriting style.
The same word three times with different letters missing.
A written example sentence for the word — the same one the voice reads aloud.
An 18-word grid to hunt the word down and circle it.
Word search, matching, secret code and maze, rotating so no two feel the same.
Checkpoints that let a child see progress — plus answer key pages, the thing reviewers always say is missing.
One switch adds a Name/Date header, so the same book also sells on Teachers Pay Teachers.
Straight renders from a book the app produced — tap any page to open it full size and read every line.

Back cover, spine calculated from your exact page count, and front cover — with the barcode area left clear the way KDP requires. The back cover even carries its own QR code so a browsing parent can hear the book before they buy it. Upload the file as-is.
A text file with your title, a written product description, 7 backend keyword suggestions, two category suggestions and a price range — generated for the exact book you just made. Copy, paste, publish.
I could have held these two back and sold them to you later. I didn't, because a $17 tool that can't produce a finished, uploadable book isn't a tool — it's a trailer.

Print a talking worksheet pack matched to this week's words. Children who need the word said aloud get it without pulling you away from the rest of the class.
Build the exact list your child is stuck on. They scan, they hear, they practise — and you get twenty minutes back.
Send home a booklet that keeps teaching between sessions, with your own words in it and audio that doesn't need you.
The audio pages live on my server at no cost to you, permanently. They're tiny text-and-audio pages; hosting them costs me almost nothing, which is exactly why I can promise it and a $5/month QR service can't.
It's a synthesised teaching voice, deliberately slowed with pauses for a young child. The phone at the top of this page is playing the real thing — that's precisely why I put it there instead of describing it.
Open the book in My Books, change what you like, generate again. It keeps its original codes, so copies already printed and sold keep working. I built that in because I knew it would happen.
Any phone camera opens the page. No download, no account, no sign-up, and nothing personal is collected from the child.
Not "value stack" filler — these are the four things that actually stand between a generated file and a live listing.
Every field on Amazon's upload screens in order, with what to put in each one, which trim size to choose, and the three settings that get children's books rejected. Follow it once and you'll never need it again.
Fill-in-the-blank title patterns pulled from how the category is actually titled — age brackets, promise words, series naming. Paste your theme in and you have a title.
A complete 20-word talking workbook, print-ready, with live QR codes. Print a page on your own printer before you build anything, so you can see exactly how the tracing lines and grids come out on paper.
The copyright page, the "this book belongs to" page and the parent instruction page — already written, ready to drop in. The unglamorous pages that make a book look professionally published.
Get in. Build a real book. Print a page on your own printer and scan it with your own phone.
If it doesn't do what this page says, email me at leo@leosterling.net within 30 days and I'll refund you. No form, no "tell us why", no hard feelings.
And your QR codes stay alive even if you refund. I'm not going to punish a child holding a printed book because their publisher asked for their money back.
I build software for self-publishers.
I built EchoBooks because I kept reading the same one-star review under children's workbooks — "my child needed me for every single page" — and it struck me that the problem was never the content. It was that paper can't talk, and everybody had quietly accepted that as a law of physics.
It isn't a law of physics. It's a QR code and somewhere to put the audio.
If a page won't generate or something breaks, you email me and you get me — not a ticket queue.
Sight Words + Spelling Grade 1, 8 activities per page, games, reviews, answer keys and a certificate — unlimited books.
A written teaching script and real audio for every word, on a QR code, hosted permanently at no extra cost.
Print-ready interior, full-wrap cover with calculated spine, and a written Amazon listing with keywords.
KDP upload checklist, 50 title formulas, a finished sample book, and front-matter templates.
A parent opens the Look Inside preview on your book and sees a QR code on every page. She scans one out of curiosity, standing in her kitchen, and hears a friendly voice teaching her daughter a word.
She hasn't seen that before. Neither has anyone else browsing that category today.
That's the whole edge — and it takes about three minutes per book to build.
And there's still a live QR code further up this page you can test before you spend a cent.
