Numbermill is a browser app that makes personalised preschool math workbooks (ages 3–6), print-ready for Amazon KDP and Etsy, in about a minute.

How it works

1. Pick where you sell: KDP paperback, Etsy instant download or Etsy made-to-order.
2. Pick the characters and the age (3–4, 4–5 or 5–6).
3. Type a child’s first name, or leave it empty for a book any child can use.
4. Press Make book and download the interior PDF plus the full KDP wrap cover (spine included).

Inside every book

• 20 activity pages: counting, more or fewer, patterns, tracing, adding
• A secret code puzzle, an answer key and a certificate
• Full KDP cover and the values to type into KDP
• Etsy-ready files and file names
• Same settings always make the same book, so reprints match

No design skills, no writing, no monthly fee. Watch the app in action: 3 short screen recordings.
