What these guides do and don't claim

We sell one of the things these pages compare, so it's worth saying how they are written.

  • No other shop's prices are quoted. Prices change whenever a competitor decides to change them, and a number printed here would be stale without anyone noticing. The comparisons are about what changes in the book, not about what it costs elsewhere.
  • No customer counts, reviews or testimonials. We'd have to invent them, and a made-up number is worse than an empty space.
  • Where we're a bad fit, the guides say so. A toddler is better served by a cheaper board book, and a gift needed tomorrow can't be written to order. Both are written down rather than skipped.
  • The AI part is stated plainly. Our books are drafted by AI and finished by a human editor, and the guide on buying AI-made books asks the same questions of us that it asks of anyone else.

How ordering works

Three steps, and the first two are done before you close the tab — nothing to install, nothing to post.

  • You pay $9.99 and tell us the child's name, age and whatever you want in the story on the payment page.
  • You upload two or three photos of them on the page you land on straight after checkout — pick the files and you're done, no email to write. Prefer email? Send them to info@kater.jp from the address you paid with instead.
  • The finished book comes back to the address you paid with as a print-ready PDF within 7 business days. If we miss that, you get a full refund without asking.

One thing worth knowing before you count backwards from a date: we're in Japan, so business days here are Japanese weekdays. Weekends and Japanese public holidays don't count, and they don't fall on the same days as yours. How the 7 days are counted is written out on the refund page. If your date is tight, email us before you pay and we'll tell you whether it fits.
