Search documented books and catalogues before spending on a complete report.
Services
Find the documentary lead, then decide the right expert review.
Start with the strongest objective evidence available: catalogues raisonnés, historical exhibition catalogues, published exhibition lists, old sales lists and art bibliography from the last 150 years and beyond. A catalogue reference can begin from $4.99; full attribution remains a human authentication service.
Dimensions, medium and date often remain more stable than translated titles.
Full title, page, reference and notes are reviewed by ConfirmArt before delivery.
Catalogue raisonné search
Search catalogues raisonnés, historical exhibition catalogues, published exhibition lists, old sales lists and art bibliography by unframed dimensions, medium, year and optional title. Full references are delivered through human review.
Authentication report
Private case intake, image and document review, comparative analysis, human expert reasoning, and a final report prepared for owners and professionals.
AI screening
A preliminary support tool for search and triage. It is not an authentication verdict and does not replace human report work.
Frame advice
A client-facing workflow where a frontal image and dimensions produce a technical frame recommendation, generated preview prompt and framer-ready material brief.
Restoration review
Condition images and documentation can be routed into a quote request for registered restorers.
Local in-person inspection
Request a quote from a regional authenticator who can travel to inspect the artwork when online review is not enough.
Advisory review
Qualified triage and documentation planning for collections, estates, galleries and professional inventory.
Authentication intake
Start with authentication, then add adjacent services when useful
Most cases begin with the artwork itself: front, reverse, signature, support, frame and provenance. ConfirmArt can refine the service scope after intake.
What to provide
Clear documentation makes the first review faster.
- Complete frontal image of the artwork
- Reverse, support, frame, stretcher and condition details
- Signature, inscriptions, labels, stamps and seals
- Invoices, certificates, provenance, catalogues or prior documentation
Human authentication
ConfirmArt does not base attribution verdicts on A.I. classifier scores.
By classifier scores we mean A.I. systems that attempt to classify an artwork as authentic or non-authentic from images. Those outputs can be confused by known training material, synthetic variation and superficial statistical similarity, so ConfirmArt does not use them to make attribution verdicts.
Our research uses catalogues raisonnés, historic sale lists, exhibition inventories, art books and archival literature, including sources more than 100 years old. We may use A.I. techniques to make research more efficient: searches, document tracking, charts, statistics and structured comparisons based on our databases and literature. Those tools help organize evidence; they do not judge authenticity.
The final opinion is formed through human review of object images, reverse, support, signature, labels, condition, provenance, comparative works, bibliography and stated limitations.

Request Authentication Service
Only your email and service selection are needed to submit the request. Optional images, dimensions and notes can be added now or later.
Payment is requested only for the Authentication report. Catalogue search, advisory, restoration and local inspection requests are reviewed first so the scope can be confirmed.
Authentication is a human expert review. ConfirmArt may use AI for bounded research support such as database, image, book or provenance searches, but not as a classifier verdict.
- Complete front image
- Reverse, support, frame and condition details
- Signature, inscriptions, labels or seals
- Invoices, certificates, provenance or catalogues
- Comparative images, references or previous opinions, if available
