Norn reads your size charts and recommends each shopper's size, fewer wrong sizes, and fewer returns. Upload an image or PDF and Norn turns it into a sizing grid you review and publish. Then surface that recommendation anywhere: the product page, a customer account, a returns portal, or your own stack through our REST API. Matching stays server-side, your chart is the single source of truth, and nothing's locked in, your sizing and results are yours to query and export.

• Remembers a shopper's measurements across every product that shares a chart.
