About this app

CatalogSnap turns your phone into a capture station for library cataloging.

Photograph catalog cards and book pages, and the app uploads them straight to your own CatalogSnap server on your local network — where they are turned into structured MARC21 records for review and import into your library system. No cloud, no third party: your data stays with you and your institution.

Built for librarians

• Retroconversion — capture printed catalog cards for digitization
• New acquisition — photograph several book pages in one batch
• Offprints — scan inventory book pages
• Subject analysis — assign subject headings from book pages
• QR pairing — connect to your CatalogSnap server in seconds

On-device and private

Card edge detection runs on the phone using Google ML Kit — the app itself needs no cloud service. Photos are held in the app's private storage until they reach your server, then deleted; they are never saved to your gallery. The app contains no analytics, no advertising, no crash-reporting SDK, and no user accounts. Your photos and catalog data go to your own server and nowhere else.

Requirements

CatalogSnap is a companion app: it needs a running CatalogSnap server on the same local network, paired once via QR code. It is intended for professional, institutional use by libraries.
