Midpoint - Card Centering Tool
Midpoint is an AI-powered mobile and web application that measures the centering of trading cards and predicts grading scores from major companies like PSA, BGS, CGC, and TAG. Users simply snap or upload a photo of a card, and the tool’s machine learning model automatically detects the card corners and print-frame corners within a second. It then calculates centering ratios, millimeter offsets, and provides an estimated grade for each supported grading standard. The app also includes a manual fine-tuning editor with draggable edge handles for sub-pixel adjustments when needed. Beyond centering, Midpoint performs an AI surface analysis that inspects edges, corners, print quality, and holographic finish, flagging any visible flaws. It generates a comprehensive report and a cleaned-up, slab-ready photo suitable for listings or sharing. The bulk upload feature allows users to drop a folder of card images and receive centering measurements and grade estimates for each card in a table, helping them quickly sort keepers from rejects before incurring grading costs. Midpoint is available as a progressive web app, as well as native apps for iOS and Android. It offers two free analyses upfront, after which users can subscribe weekly or semi-annually for unlimited use. The tool is designed for any lighting or background conditions and works on any card photo, though optimal results require a flat, well-lit capture.
