The concept
Endpaper turns every indie bookstore's "Staff Pick" into a 60-second AI-narrated audio pitch in the bookseller's own voice — printed onto a shelf-talker as a QR code. A customer who's never spoken to a bookseller can suddenly hear Maya from the front desk explain why this novel changed her life — at 3pm on a Tuesday, while standing in front of the shelf. Stores see which talkers convert and re-cut their picks weekly with one click.

Where it stands
The archived incubator verdict was BUILDIT. That is an internal research signal, not a current market claim.
