Frequently Asked Questions

What is AI autograph authentication?

AI autograph authentication (also known as AI signature authentication) uses pattern recognition to analyze handwriting and signature characteristics. The system compares signatures against verified reference data to identify consistencies or potential concerns related to authenticity.

Can AI verify a signature's authenticity?

AI can assist in assessing signature authenticity by identifying patterns, inconsistencies, and visual features within an autograph. While no authentication method is 100% conclusive, AI-based analysis provides consistent and objective insights to support collectors and buyers.

How accurate is Signatrue's AI autograph analysis?

Signatrue's AI autograph analysis is designed to deliver consistent and repeatable results based on signature pattern comparison. Each review provides a clear outcome such as “Likely Genuine” or “Not Genuine” to help users make informed decisions.

What is the difference between Rapid Review and Pre-Authentication?

Rapid Review is based on submitting a public auction or marketplace link and is intended for quick pre-purchase checks. Pre-Authentication requires uploading photos of the autograph and provides a deeper analysis with a permanent certificate.
