SynthID Detector expands access

Google has expanded SynthID Detector to everyone globally in English. The tool checks supported images, video and audio for signals associated with AI generation from Google and participating partners.

A watermark is one piece of evidence

The Google announcement names partners including OpenAI, NVIDIA and Kakao, with Apple described as coming soon. The detector extends earlier access aimed at media professionals and joins verification features in Google’s consumer products.

Google expanded English-language access to SynthID Detector for checking supported AI-generated images, video and audio. The service looks for watermarks from participating tools, so its coverage depends on the origin and processing of the content.

The scope is supported watermarked media. It is not a universal test for whether a file is authentic, accurate or made by a person. Content from other systems, and changes made after generation, can complicate what a detector is able to find. The absence of a detected signal cannot settle the question by itself.
