Colophon

Provenio is a knowledge graph of art history — 282,731 nodes, 5,796 artists, 86,841 works, three centuries of transactions — served through 27 tools any AI assistant can call. The piece you just saw, Genesis, is that graph breathing: real masters, on a real timeline, synchronising on real lines of influence. Nothing on this site is invented.

A language model will, when it does not know, invent a plausible answer. For art — for provenance, attribution, restitution — a plausible invention is worse than silence. So Provenio is built to refuse it: every claim is bound to a source row, and where the record is empty it returns the empty seat rather than a guess. The honesty is not a disclaimer. It is the engineering.

One person, end to end: the ontology and graph (CIDOC-CRM · PROV-O), the Model Context Protocol server and REST API, the evaluation harnesses that certify quality externally rather than by self-report, six-language localisation in an auction-house register, and the artwork you are standing in. Built with an agent system of the maker's own design — the same method offered to clients.
