Google has made its SynthID Detector publicly available at synthid.com, giving anyone a single destination to check images, video, and audio for invisible AI watermarks. The tool supports watermarks from Google's own Gemini models as well as those from OpenAI, Nvidia, and Kakao, with Apple support expected soon. All three sources agree that the launch expands access beyond the journalists and media professionals who previously tested the tool.
The sources differ slightly on details. Ars Technica notes that the login requirement and daily quota of about 10 checks are meant to stop people from using the detector to develop removal tools, while Engadget and TechCrunch focus more on the practical limitations. All three emphasize that SynthID Detector is not a universal checker: it cannot identify content from companies using different standards, such as Meta, and watermarks can be stripped in some cases. TechCrunch adds that Google says people already make 1 million verification requests per day through its other tools.
Despite the caveats, the new website is a step toward easier verification of AI-generated media. It will not tell users which specific model created a file or which parts were edited, and it requires a login, but it consolidates checks that previously meant asking Gemini or visiting separate detectors. As Engadget puts it, the site makes these capabilities easier to access for people not already using Google's AI tools.
