Google launches SynthID media verification site to publicly identify AI-generated content
Understand the story
Google has launched the SynthID verification website, allowing anyone to upload images, video, or audio to detect whether they were AI-generated. Previously the tool was only open in testing to selected journalists, media professionals, and researchers; with this launch it is open to everyone. According to TechCrunch on October 7, 2026, supported formats include images such as JPG, PNG, WEBP, and GIF, videos such as MP4, MOV, and WEBM, and audio such as WAV, MP3, OGG, FLAC, AAC, and M4A. The same day, Ars Technica reported that the SynthID detector went live at SynthID.com and can now identify watermarks from all partners; previously external users could only query watermarks through Gemini, and the old detector only recognized Google's own SynthID, so content like ChatGPT images carrying SynthID watermarks was not flagged. According to The Decoder on October 8, SynthID Detector can detect invisible watermarks in content generated by models such as Gemini, Veo, and Lyria, and over 180 billion images and videos now carry SynthID watermarks. That report listed the supported formats as JPG, PNG, MP4, and MP3.
