Hi Product Hunt, I'm Dau and I made DT Labs.
DT Labs is a set of browser tools for people who make puzzle books, activity books and printables to sell on Amazon KDP and Etsy: word search, sudoku, crossword, maze, nonogram, cryptogram, kakuro, Mathdoku, Bimaru, bingo cards, dot-to-dot, mandala, planners, math worksheets and tracing worksheets.
I wanted puzzle pages I could trust, so every puzzle is built from its rules by an algorithm, not AI. Sudoku, kakuro, Mathdoku and Bimaru puzzles are checked to have exactly one solution. Each tool builds a print-ready PDF at KDP trim sizes, with answer keys. You can make and preview everything with a free account; free exports carry a watermark, and DT Labs Membership exports clean files with a commercial licence.
There are also free KDP calculators for spine width, royalties and trim sizes, and free printable sets (Thanksgiving, Christmas, math and tracing worksheets) if you just want pages to print.
Making and previewing is free. Paid apps for research and marketing are sold separately.
Which puzzle type or trim size would you like to see next?
