Stamp collecting

A stamp collecting app that starts with a photo of the page

Photograph an album page or a stock card. AI drafts an entry for each stamp it can make out, with a cropped photo — you correct the drafts and add what a philatelist actually records: country, year, denomination, condition.

Twelve fictional collectible stamps with landscapes, birds, and plants arranged on a dark album page.

What you get

Three things a stamp collection has to keep straight

Work a page at a time

Photograph the album page as it sits. AI drafts an entry per stamp it can make out — and for the singles that deserve their own portrait, photograph them individually and the entry keeps every shot.

Condition, in your own terms

Mint, used, hinged, the centring you would call it — the description and tags are free-form, so the collection is recorded in the vocabulary you already use, and searchable by it.

A value on the whole collection

Record a value per stamp or per page lot, then export an itemised PDF with totals or a spreadsheet when insurance documentation or a sale needs figures rather than memory.

How it works

From an album page to a catalogued collection

  1. The Keeper of Things capture sheet: catalogue a space, choose from gallery, or add manually.
    Step 01

    Photograph an album page or a stock card at a time.

  2. The Keeper of Things review screen showing items the AI detected in a photo, ready to accept.
    Step 02

    AI drafts an entry per stamp it can make out; you correct and confirm.

  3. The Keeper of Things inventory catalogue listing items with photos, locations, and categories.
    Step 03

    Country, year, and condition, searchable across every album.

  4. The Keeper of Things inventory grouped by category, showing Electronics and Furniture groups.
    Step 04

    Albums, stock books, and the box of covers — one collection.

FAQ

Cataloguing stamps, answered

Still curious? Reach us at [email protected] .

Can I group by country or era?

Yes — tags are free-form, so tag by country, period, or theme and search any of them back out. Collections keep one list across albums, so a themed set of entries reads together even when the stamps live in three binders.

Does it identify stamps or look them up in a catalogue?

No. There is no catalogue lookup — the AI describes what it sees in the photo, and the attribution stays yours: country, year, watermark, perforation, whatever catalogue numbers you use. The app’s job is keeping that record straight, not second-guessing it.

Stamps are small — will the AI catch every one on a page?

It drafts an entry for each stamp it can make out, and a crowded page will need some corrections — that is what the review step is for. Add anything it missed by hand in a few seconds, or photograph the important stamps individually for a cleaner record.

Is my collection private?

Yes. It is tied to your account, encrypted in transit and at rest, never sold, and never used for advertising. It is shared only if you invite family members to it.
