For mineral collectors
Catalogue your mineral collection. Design and print collector-grade labels. Keep your data on your computer.
ClearBench is a native desktop app built for mineral collectors who want their catalogue to be theirs alone, with IMA-approved species names, Mindat locality and minID fields, acquisition stories, and photos. Not a web service. Not a spreadsheet. Not a database that someone else can read.

Three things, done well.
ClearBench isn't trying to be a database, a label printer, and a cloud sync product all at once. It's a focused desktop app that does the three things mineral collectors actually need.
Catalogue every specimen
IMA species autocomplete, Mindat locality and minID fields, dimensions, weight, hardness, fluorescence, acquisition story, who you bought it from, what you paid, where it sits today. Your full mineralogy on your machine, cross-referenced with the records the field already uses.
Design your own labels
Six starting templates designed for cabinets and show tables, all at 50×40mm. Twelve bundled fonts. Full control over every field, font size, and alignment. Output a sharp PDF at exact size and print it on your own printer. A4 and Letter sheet layouts ship today.
Keep your locality private
Mineral localities don't belong on a third party's server. ClearBench stores everything on your computer. No upload, no telemetry, no analytics on your specimens.
Selling at shows? Built for that too.
Show mode tracks every sale from setup to pack-up. Track stock separately from your personal collection, scope to the active show, record sales as they happen, print label sheets and price tags. Same app, same privacy, no extra purchase. ClearBench is built for how mineral dealers actually work.
Track stock at every show
One inventory list across every show you do. Filter to the items you have on the table right now, scan a SKU, mark it sold. Prices, locality, photos, all on the table-side device.
Record sales as they happen
A sale is two clicks: pick the piece, enter the price. ClearBench logs the date, the show, the buyer (optional), and the actual price paid. End-of-show reports show what sold, by show, by category, by margin.
Print price tags + bulk-import
The same label engine prints price tags at the size and shape dealers actually use. Drop in a CSV of stock from your spreadsheet to bulk-load a fresh table; round-trip back to Excel any time.
Built for mineralogy, not generic cataloguing.
ClearBench knows what a mineral specimen actually carries on its label and in its record. The fields are the ones you'd expect to see in a serious collection catalogue.
Your localities never leave your computer.
Locality data has consequences. A precise mine + pocket name in a searchable database can attract amateurs, devalue specimens, or even put a site at risk of cleanout. ClearBench's privacy architecture isn't a marketing line. It's the only sensible default for collection data.
Stored on your device only
Every specimen, photo, and locality string sits on your computer. No upload, no copy on any server, no third-party access, including ours. We literally cannot read your collection.
No analytics on your records
No telemetry on what you type, photograph, or print. We don't track which mineral names you search or which localities you record.
Backups stay yours
Full-catalogue backups are plain .clearbench JSON files you save where you want: your hard drive, an encrypted external, your own cloud. For day-to-day work, export any collection straight out to CSV, Excel, plain text, or a vCard for contacts, then round-trip back in after a bulk edit. The format is documented and stable.
No lock-in
If we vanish tomorrow, your collection is still yours, in a format you can re-import into other tools. The .clearbench backup file is plain JSON that opens in any text editor; the CSV, Excel, and plain-text exports open in tools you already have.
Labels that earn their place in the cabinet.
Six bundled templates from clean to ornate, with full control over font, size, alignment, and prefix. All text rendered as SVG paths via opentype.js, pixel-accurate at every zoom and on every printer.

Common questions from mineral collectors.
Does it use the IMA-approved mineral name list?
+
Yes. The mineral name field autocompletes from the IMA-approved species list bundled in the app, with no Google or Mindat API call. When you confirm a mineral, ClearBench autofills the chemical formula, crystal system, IMA status, Strunz class, Mohs hardness, specific gravity, and Mindat ID from the bundled Wikidata snapshot. You can edit any field afterwards. Common trade-name variants (gem names, marketing names) trigger a 'did you mean' warning before commit.
Does it record Mindat locality IDs and minIDs?
+
Yes, both as first-class fields. Every specimen carries a Mindat locality ID (the six-character locality reference, e.g. 13513 for Sweet Home Mine) and a Mindat minID (the per-specimen ID for collectors who've registered theirs). They're searchable, render on labels if you want them to, and round-trip cleanly through CSV import / export. Cross-reference your collection with the database the field already uses, without having to rely on it being online.
Can I import my Mindat data? Does it sync live with mindat.org?
+
Not live. ClearBench imports CSV files (per-collection round-trip), so you can export a CSV from Mindat or any spreadsheet and bring it into ClearBench, but there's no always-on API connection to mindat.org. That's deliberate: a live sync would mean your acquisition prices, locality precision, and personal notes touch a third-party server every time you edit, which would compromise the privacy model collectors come to ClearBench for. CSV covers the actual workflow (one-time import, occasional sync) without the privacy cost.
Will the labels print on Avery sheets?
+
The print composer renders an A4 sheet with a 4×7 grid (28 labels at 50×40mm), centred with margins to match the most common cabinet-label sheet sizes. PDF output is exact-size; what you see on screen is what comes out of the printer. Custom sheet sizes for non-Avery formats are on the roadmap.
How does it handle locality hierarchy?
+
Localities are structured as mine / district / city / state / country (with mineral-relevant labels: 'mine' instead of 'street'). Each level is optional. The label rendering joins the non-empty levels with commas, so a specimen with just country reads naturally, as does one with the full chain. You can also override the joined locality on a per-label basis when you want the label to read differently than the catalogue record does.
What about photos? Where do they live?
+
Drag photos from your computer straight onto a specimen, one at a time or a whole folder at once. iPhone HEIC photos work without any conversion step once they're on your computer. Everything's stored locally; nothing's uploaded anywhere. The first photo on each specimen becomes the cover image you see in the catalogue, and you can swap it any time.
Can I track loans, valuations, and provenance?
+
Yes. Each specimen has loan history (current borrower + a log of past loans), insurance / valuation fields, ex-collection / provenance attribution, and timestamped field notes. There's also a 'specimen links' feature for cross-referencing related pieces ('same pocket as MIN-0042'). A provenance chain document can be exported as a PDF for any specimen.
