Mineral Collection Tracker & Manager - Free Digital Catalog for Collectors

Cabinet No. 40 Collector Panel is a cloud-based web app for mineral collection management and keeping your own specimen catalog online. Built for collectors who want order in their specimens: fast search, one consistent record per piece and a public profile to show the collection to others.

Cloud catalog. Each specimen is stored once, with name, locality, size in mm, mass, acquisition date and your own notes. You attach high-resolution photos. Everything is available from any device, no install needed.

Virtual cabinets and shelves. You arrange the collection into cabinets and shelves, mirroring how it physically sits at home. Every specimen can have a fixed slot, so you always know what is where and the layout shows up on your public profile.

Bulk import from Excel and CSV. If you already have a spreadsheet, upload it - the column mapper lets you map your headers to panel fields, parses sizes and detects duplicates by signature (full_id or the combination of name + location + size). You choose whether to skip or overwrite duplicates.

Printable collector cards. The built-in Figma-style layout editor lets you design your own card: from a small under-specimen tag to a full A5 sheet. You pick which fields are printed, add a collection logo and export a print-ready PDF for the selected specimens.

AI-assisted mineralogical descriptions. A Gemini-powered assistant generates a four-section description from species name and locality. Available in English, Polish, Spanish, Italian, German, French, Japanese and Portuguese - all output is fully editable.

Public profile and sharing. Every collector gets a public profile with virtual cabinets, an origin map, mineralogical class statistics and a wishlist. A single specimen can be shared by link without exposing the rest of the collection.

The Hobby plan is free forever up to 20 specimens. Paid plans (Starter, Explorer, Curator) raise the specimen, print layout and AI generation limits. An annual Pro subscription is available. Whether you call it mineral collection management software, a mineral cataloging app or a specimen manager - this is the dedicated tool for it.

Field mode (beta). Quick offline specimen sketches in the field - snap a photo, save name and locality. Once back online, sync everything with one click. Quick specimen capture (beta) lets you add a new specimen in seconds without filling the full form.
