Upload photographs of a piece from several angles and Provenance X returns a
structured reference opinion: a reading of the form and workmanship, an estimated
date range, flagged features that give pause, and the visually closest objects
retrieved from museum collections and auction results worldwide, compared point
by point.
What this opinion is
The report is generated by AI. It is a reference opinion, not a verdict.
It is not a certificate, it does not replace hands-on examination by a qualified
institution, and it should never be your only basis for buying, selling or valuing
a piece. Final judgement on authenticity and value rests with an accredited
institution examining the object itself.
What it does
- Reads every angle — form, body and glaze, decoration, reign mark and foot ring each get their own line, not one vague sentence
- Estimates a date range — a range with the reasoning behind it, rather than a single confident year
- Flags what does not fit — including features that contradict the proposed dating
- Compares against real objects — visually similar pieces from museum collections and auction results, with sources and hammer prices
Reference data
The search set covers published collection data from a number of public museums
together with published auction results, a substantial share of which carry real
realized prices that can be used for comparison.
