How it works

1

Set up your book

Title, how many puzzles, age group, trim size. Pick themes from a list of 42, type your own, or leave it empty and let the AI choose.
2

Copy the prompt into any AI

One click copies it. The AI sends back the words and the kid-level clues. Copy its answer.
3

Paste it back and download

The app builds every grid, numbers the squares, lays out the pages and adds the answer key. Then you download the PDF interior.

The AI picks the words. The app builds the grids.

That split matters. Ask an AI to draw a crossword and it invents squares that do not line up — two words crossing on letters that do not match, numbering that skips. You only find out after you have printed a proof copy.

So the AI is only asked for the part it is good at: words and clues. The interlocking is done by the app, the same way every time.

Every crossing letter is shared by both words, and the squares are numbered in reading order — the way a solver expects to read them.

What lands in your PDF

Title page, copyright page and a "This book belongs to" page
A how-to-solve page with a worked example, so a child can start alone
One puzzle per page with Across and Down clue lists
An optional word bank under each puzzle for younger solvers
A full answer key at the back, four filled grids to a page
An optional thank-you page at the end
Up to 60 puzzles in one book

Turn any of those pages off if you do not want them.

Three age levels, and they really are different

Pick the age group and the whole page changes with it — how many words, how long they are, how big the squares are, how the clues are written, and whether the answers are listed at the bottom.

Click any page below to open it full size.

Sample puzzle page for ages 6 to 7 — **Ages 6–7** 6 words of 3 to 5 letters. The squares grow to fill the page for small hands, and every answer is listed in a word bank at the bottom.

Sample puzzle page for ages 8 to 9 — **Ages 8–9** 10 words of 3 to 7 letters, clues written at a third-grade reading level. Word bank still there if they need it.

Sample puzzle page for ages 10 to 12 — **Ages 10–12** 14 words of 4 to 9 letters in a denser grid, and no word bank — at this level they spell it out themselves.

Set up for KDP, not just for printing

The margins are the part that gets books rejected or trimmed badly. They are already handled:

Inside margin (gutter)	0.75 in — KDP asks for at least 0.375 in
Outer, top, bottom	0.50 in — KDP asks for at least 0.25 in
Mirrored pages	Wide margin on the left of odd pages, on the right of even pages
Minimum page count	Padded to 24 pages automatically, and kept to an even number
Fonts	Embedded in the PDF
Resolution	Vector text and lines, so there is no DPI to worry about
Trim sizes	8.5 × 11, 8.25 × 11, 8 × 10, 7 × 10, 6 × 9 in

A panel in the app shows these numbers for your book while you work, with the KDP minimum next to each one.

What else you could use

Free crossword makers on the web will build you a puzzle. They hand back one puzzle as an image or a single sheet — you still have to place it on a page, set the margins, build the answer key and assemble the front matter yourself, once per puzzle.

Ready-made PLR puzzle books are cheaper still, but every other seller has the same pages.

This app is for the step in between: you want your own books, with your own themes, laid out correctly, without doing the layout.

What it does not do

It is built for children. No cryptic clues, no adult-size grids.
It is English only.

Runs in your browser with no install, no account and no monthly fee
Works offline. Nothing you type is uploaded anywhere.
A README with the three steps written out
Unlimited books, and you keep 100% of what you sell

Questions

Do I need to be online?

Only for the AI step, because the AI runs in your browser on their website. The app itself works with your Wi-Fi off.

Windows or Mac?

Both. Any current browser — Chrome, Edge, Firefox or Safari.

Do I have to tell Amazon the puzzles came from an AI?

Yes. KDP asks you to declare AI-generated content when you publish, in a section of the upload form. It is private to Amazon and never shows on your book's page. The app prints a line on your copyright page saying the puzzle content was generated with AI assistance.

Can I sell the books I make?

Yes, on KDP or anywhere else. You keep all of it. You may not resell or give away the app itself.

Which AI should I use?

Any of the four. Free ChatGPT and free Gemini both handle it. For a big book, ask for ten puzzles at a time and use the "Add to book" button — the app joins the batches together.

Can I come back to a book later?

Yes. "Save book file" stores your whole book in one small file. Open it again any time to reprint or change it.

What if it does not work for me?

Email me within 30 days and I will refund you. Tell me what went wrong if you have a minute — that is the part I actually need right now.
