COLLECTORS CATALOGUES
CREATE YOUR OWN MUSEUM

A cataloguing app for antiques

The story of an antique is half its worth — and stories evaporate when they live in someone's head.

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

Provenance that cannot be quietly rewritten

Every object carries a provenance chain that is append-only: bought at the Halifax flea market in 1998, inherited from your grandmother, restored in 2015. You can always add to the story; nothing lets you silently rewrite it. In ten years, that discipline is the difference between a documented piece and an anecdote.

A record you will be glad you made

Photographs from every angle, measurements, materials, maker's marks, condition and an honest note about what you do not know. Each piece gets a permanent number in your own register, and your records export freely — they are yours, not ours.

A museum, not a shop

There is no marketplace here and never will be: no valuations, no listings, no advertising. Arrange your pieces into museums of your own, share a museum with family or keep it private, and tick off the real museums you visit along the way.
