Questions
Answers before you ask
Patina is not open yet, so any price, trial or plan named in these answers is planned rather than on sale.
Does Patina tell me what my item is worth?
No, and it never will. Patina identifies maker, era and origin, and it does not produce a dollar value or price estimate. Valuation is a professional's job and we say so on every result.
How reliable are the identifications?
Every result is an AI-generated estimate, not an expert appraisal, and it should not be the sole basis for a purchase or sale decision. That is why each result carries a confidence level and a persistent disclaimer, and why low-confidence results are flagged rather than dressed up.
What does the appraisal flag actually do?
When the model's confidence falls below the set threshold, the result is flagged and you are given a referral link to a vetted appraiser. It is a handoff, not a verdict.
Is there an iOS or Android app?
Not at launch. Patina runs as a mobile-first web app you open in your phone browser, with camera capture or photo upload built in. Native app store distribution is not part of this build.
What happens to the photos I take?
A photo you submit is sent to a multimodal vision model to produce the identification, and your ten most recent results stay in your own signed-in history. The privacy page sets out the detail.
Do I need an account?
Yes. Scans are tied to an account so your monthly quota and your history work, and you can sign in with email and password or a magic link.
When can I use it?
Patina is pre-launch and the waitlist is open. Join it and we will write to you when scanning opens, with no other mail in between.
