• Ossus AI add-ons Application

  AI add-ons for library management: an inventory feature that identifies books by reading the spines in photos of up to 30 books on the shelf, a vendor comparison agent that splits a purchase list across book vendors, and a grant agent that finds grants a library qualifies for, tracks deadlines and writes applications; they run with Ossus's own library system or alongside an existing one, sold through a booked meeting with no prices published.
