Worth noticing
It explicitly says it cannot detect SynthID from pixels and treats missing provenance as inconclusive.

Field notes

The page separates readable provenance layers from vendor-specific checks that remain outside its reach: for example, it says Claude text checking needs Anthropic's key and SynthID pixel detection requires official portals. Its FAQ also cautions that screenshots, re-encoding, and platform processing can strip metadata, so a negative result is not a reliable authorship verdict.
