COLLECTORS CATALOGUES
CREATE YOUR OWN MUSEUM

An artifact database for private collectors

Museums solved artifact record-keeping long ago. This brings the same discipline to a private collection.

Collectors Catalogues is free on Android, works in the browser, and carries no advertising and no marketplace. Get the app → · About it

Records with a museum's spine

Every artifact gets an accession-style permanent number, photographs, measurements, materials, condition, and a written examination. Identifications carry confidence levels and a "why I think so" — because "Roman, probably 2nd century" recorded honestly is worth more than a confident story that falls apart under one good question.

Recording history without endangering it

Findspots are exact for the owner and blurred for everyone else, location data is stripped from uploaded photographs, and there is no marketplace: no prices, no route from "found it" to "sold it", no advertising. The point is documentation — collections that end up better recorded than they would otherwise have been.

More than storage

Put an object on a turntable and let people spin it. Ask the identification board about the piece that defeats you. Join a project with other collectors around a shared question. Or keep everything entirely private — the record is the point, and it is yours to export at any time.
