Number Mystery Publisher Studio

An 8-step publishing studio for number-mystery puzzle books: titles, custom number lists, cover prompts, Etsy listings, promo kits, next-volume pages and a master AI prompt.

Number Mystery Publisher Studio
A publishing companion for number-mystery (find-the-number) puzzle books. Enter your project once, then use 8 builders: title and series lab, custom unique number list generator (TXT/CSV download), cover prompt builder, Etsy listing builder, promo content kit with a 7-day plan, next-volume back-page CTA and a master AI publishing prompt. It builds everything around your finished interior; it doesn't create or verify the puzzles themselves. Saves projects in your browser, exports/imports JSON, and works offline.
