How to check a Keepsake or delivery

Use the option that matches what you received: a file, a file id, or a full Keepsake.

Anyone can use yubikiri.art/verify. You do not need an account. Your file is checked on your device — we never upload the art itself.

Option 1 — Drop the file you received

Open Check a Keepsake or delivery.
Drop the exact final file the artist delivered (or choose it from your device).
If it matches, you'll see which completed room it came from and the artist's public page.

Only the exact file matches. A resized JPEG, a screenshot, or a re-exported PSD will not match.

Use a link that looks like /verify?credential=yk_cc_…, or paste the yk_cc_… id on the verify page.
You'll see the file name, artist, and whether the record still checks out.

This confirms the process record for that exact file.

Paste a Keepsake id (yk_ks_…) or open a link that includes it.
Read whether the sealed process record checks out, whether its finals still match, and whether it has reached the daily public list.

Full walkthrough: Keepsake guide.

Match: the exact file or record matches a completed Yubikiri commission room or solo piece.
No match: Yubikiri has no matching delivery record for that exact file. Many honest copies (resized, compressed, recolored) will not match.
