One edit, everywhere, immediately
Canva has no publish-and-update layer: once a book is exported, emailed or printed, every copy is frozen. Change the gate code, lose a restaurant, add a house rule, and each copy has to be produced again. chucho holds the property's content in one place. Edit it and the public page, the phone guide and the tablet all read the new version on their next load — including the copies already in a guest's hands.
