What It Is
You create puzzle and activity books built around one theme, such as a season, a hobby or a specific audience, using an AI tool to generate word lists and layouts, and publish them on Amazon's print-on-demand service.
The Pitch
Kimberly shows a themed activity book that an Amazon sales estimator puts at about 100 or more copies a month, and says each new theme is 'just a new word list away'.
Who It’s Best For
People who enjoy puzzles and can spot specific audiences.
The Truth (as we see it)
Sales estimates come from a third-party tool, not the publisher. Puzzle books are a crowded KDP category, so a distinct theme and careful checking of AI-made puzzles matter. The video is sponsored by Genspark, the AI tool she demonstrates.
