Bring your own words
Paste any list of answers and clues — we validate it as you type and interlock the words for you.
Criss-cross layout
Words cross where they share letters, with no black-square grid to fill — perfect for themed and kids' books.
Print-ready PDFs
Every export pairs puzzle and clue pages with a matching solution key, sized for KDP.
Why not use a free generator?
Free generators are fine for a worksheet or a rainy afternoon. A book you sell on Amazon KDP needs the right to sell it, and pages made for print.

Frequently asked questions
How is this different from the regular Crossword tool?
The Crossword tool builds dense, symmetric New York–style grids where every square is part of two words. This free-form tool interlocks just the words you supply in a lighter criss-cross layout — ideal for custom word lists and themed books.
Can I use my own words and clues?
Yes — that's the point. Paste any list as ANSWER: clue, one per line. The editor validates each line and tells you exactly what to fix before you generate.
Do the PDFs include the solutions?
Every export includes matching solution pages alongside the puzzle and clue pages, so your book is complete.
Do I need an account to use the generator?
You can browse this page without an account, but generating and exporting puzzles requires signing in and credits.
Can I use designs from a free online generator in a book I sell?
Check its license first. Many free generators allow personal or classroom use only, so putting what they make into a book you sell can break their terms. Their downloads are usually sized for screens rather than print, too. Everything you create in Publish Aid is licensed for commercial use and exported as a print-ready PDF sized for Amazon KDP.
