Never buy the same book twice.

Point your phone at the bookshelf and Shelfmark catalogs every book your kid owns — then answers the only question that matters at the store: do we already have this one?

How it works

One photo does the cataloging

1

Snap the shelf

One photo captures the whole row — board books, worn spines, sideways stacks. Seconds, not an afternoon.

2

Tap to confirm

Most books add themselves. When two look genuinely alike, Shelfmark asks instead of guessing. One tap settles it.

3

Share the shelf

Send one link to the people who buy your kid books. They check it from any store aisle — no app, no account.

Built carefully

The boring promises, kept

Photos are not kept

Shelf photos are processed and then deleted. Individual book images are saved only if you opt in.

It never bluffs

A wrong “already owned” means a missed gift. When a match is uncertain, Shelfmark asks you — it does not guess.
