Google has opened SynthID Detector globally in English, expanding access beyond media professionals. Anyone can check images, video and audio for hidden marks from Google and participating providers OpenAI, NVIDIA and Kakao. Apple support is planned later. The change gives the public access to a provenance signal for supported media, rather than a guarantee that every AI-generated file can be identified.
Google opened SynthID Detector to everyone on October 7, with access available globally in English. The earlier version was limited to media professionals. The free website lets people submit an image, video or audio file for a check. It looks for SynthID, the hidden watermark that participating AI tools add to the media they create, giving an indication of that content’s origin.[1], [2]
The detector checks media from Google and participating providers OpenAI, NVIDIA and Kakao. Its scope depends on those supported marks: the public opening does not turn it into a checker for every possible AI creation. An image, a video sequence and an audio file are all eligible media types. The announcement concerns detecting the invisible marks within those files, rather than certifying the truth of what their contents portray.[1]
Google says SynthID has marked more than 180 billion images and videos since its launch in 2023, alongside 240,000 years of audio. Built-in checks in Search, the Gemini app and Chrome now handle more than one million requests daily, according to the company. Apple support is a forthcoming addition to the detector’s current provider list. These existing checks accompany the newly opened public website.[1]
