What Numbermill does
Numbermill is a browser app. The buyer chooses the age (3–4, 4–5 or 5–6), the characters and where they sell, and types a child's first name or leaves it out. It makes a 37-page preschool math workbook (counting, tracing, patterns, mazes, a secret code from the name, a certificate and answers) and the full KDP cover sized to the page count and paper. Every answer is checked by the computer before the book can be downloaded.
Honest limits: no page editor, ages 3 to 6 and early math only, and the characters and layouts are shared by everyone who uses it.
The sales page is the demo: visitors flip through a whole book and type a name to see the cover made in front of them. Screen recordings of the app (first book, a personalised Etsy order, a day of Etsy orders from the CSV) are on the how-to guide.
Who the buyer is
KDP publishers. Paperback workbooks with the interior and the full cover ready to upload.
Etsy sellers. Instant-download PDFs, or made-to-order books with the child's name.
Teachers Pay Teachers. No-name PDFs in black and white, easy to print for a class.
Parents and grandparents. A one-off book for a child you know, printed at home.
Not a fit, so please don't send them, for buyers who:
- want to draw your own characters or move things around on the page (there is no page editor)
- need ages over 6 or subjects other than early math
- need trim sizes other than US Letter or A4
- expect sales without doing your own listings and marketing
Why it is easy to promote
Proof on the page. Visitors flip through a real book and make a sample cover with any name.
Low price. $7 once, no subscription, 30-day refund.
Clear audience. KDP, Etsy and Teachers Pay Teachers sellers, plus parents and grandparents.
An honest page. No fake countdowns or earnings claims, so your readers keep trusting you.
Email swipes
Copy, edit to your voice, and replace the parts in curly brackets.
