How it works

Nothing about the process is a black box. Here's exactly what happens between your upload and your download, and why it's built this way.

Upload

JPEG, PNG, or HEIC (converted automatically). One photo is the whole input.

No folder to curate, no batch to assemble first — the everyday case is the one favorite shot from a trip, so that's the whole first step. A whole Field Trip Folder is possible later, but never required to start.

Location & date, confirmed

Pulled from your photo's EXIF GPS and reverse-geocoded automatically. Wrong guess? Edit either before generating.

EXIF and reverse-geocoding can be wrong — a phone's clock, a stitched panorama, a photo taken indoors near a window. Rather than trust the guess silently, it's shown to you and stays editable until you confirm it. What ends up on the card is only ever what you confirmed.

Customize, previewed live

Paper texture, caption font, layout, and photo filter — see the change before you commit to it.

A handful of real choices, not a full editor — every option previews instantly, so nothing about the final card is a surprise at generation time.

The stamp is painted

A field researcher's stamp is painted for your scene: transparent background, no rendered text, your photo untouched.

Your original photo is never sent anywhere to be redrawn. Only a short description of the scene goes to image generation, and only to produce a small, transparent-background stamp — decoration next to your photo, never a replacement for it.

Composed, not arranged

Photo, stamp, aged paper, and a typeset caption are assembled into the final 3:2 postcard deterministically — never left to a model to lay out.

The layout is fixed code, not a prompt: roughly 58% photo to 42% paper, every time. The same inputs produce the same composition, so the result is dependable rather than a fresh roll of the dice per card.

Yours to keep

Download the PNG — it's saved to your ledger automatically. Add a back side, message and address, whenever you're ready.

Every card gets a reference number and a place in your ledger the moment it's made — not just a download, an entry. The idea holds up best on the second and third card, not the first.
