Archival Index Card Detector

Upload any archival scan — single card, multi-card sheet, or full page — and the model will draw a box around every index card it finds. Trained on a mix of NLS Advocates Library pages, US Navy multi-card biographical records, and cropped BPL + Rubenstein cards.

Find a failure case? It becomes training data for the next iteration — open an issue on the model repo with the image.
