AI Watermark Database

A filterable watermark database and archive of documented provider claims — provider, mechanism, claim status, evidence authority, AWC support, and last verified. Not a watermark certificate search or a complete catalogue of every AI system.

How to read a record

Evidence authority

Official, independently verified, observed, or unverified — the strength of the source, not the polarity of the claim.

Claim status

Documented, ruled out, conditional/partial, unknown, or not applicable.

Provider detector availability

Public, announced, unavailable, or unknown. Announced is not public.

AI Watermark Center support

Available, not available, planned, or not applicable. Support does not prove the provider mechanism exists.
