Starting with Itō Jakuchū • Expanding to Edo-period Japanese art

Authenticity risk scoring for Japanese artist seals — with explainable AI.

Upload a photo of a hanging scroll or painting. We detect the seal, compare it to authenticated references, and generate a client-ready report with an authenticity probability and a clear explanation.

Designed for collectors, galleries, auction houses, and labs. Human expertise stays in the loop — AI makes it faster, consistent, and scalable.
What you get
Client-ready documentation, designed for trust

Risk score + probability

Calibrated output designed for non-technical decision makers.

Explainable factors

Stroke structure, seal geometry, ink diffusion cues, and confidence tier.

Audit trail

Seal crops, match references (when available), and report metadata.

Product

A practical workflow that turns one photo into a seal-based authenticity assessment and an explainable report.

Seal Detection

Finds and crops seals from complex artwork photos (scrolls, paintings).

Similarity Engine

Compares the seal embedding to authenticated references (metric learning).

Explainable Report

Converts similarity into probability + readable reasoning and caveats.

Who it’s for
Fast pre-screening, triage, and documentation
  • Collectors & dealers: reduce uncertainty before purchase.
  • Auction houses: consistent pre-check at scale.
  • Museums & labs: structured evidence for internal review.
  • Insurers: risk scoring and repeatable documentation.
Why we start in Japan
A perfect “beachhead” for trust + data moat
  • Rich seal/signature culture → strong visual features for AI.
  • High-value, trust-based transactions → explainability matters.
  • Scalable into ukiyo-e, lacquer, ceramics, and wider Asian art.
Important: JapaneseSeal is an AI-assisted system. It does not replace expert judgment—its purpose is to accelerate verification and provide consistent, documented analysis.
