Google opens SynthID verification site to the public
What happened
On 7 October 2026, Google launched a new website where anyone can verify whether an image, video or audio was generated by AI. The tool had previously been available in testing only to selected journalists, media professionals and researchers. The site supports a range of image, video and audio formats including JPG, PNG, MP4, MOV, WAV and MP3, with detection based on Google's SynthID watermarking technology introduced in 2023. On 8 October, The Decoder reported that Google had opened SynthID Detector to the public, allowing anyone to check whether images, video or audio were generated by AI from Google and its partners. The tool can identify invisible watermarks embedded by models such as Gemini, Veo and Lyria, and supports JPG, PNG, MP4 and MP3 formats. The report also said 180 billion images and videos already carry watermarks.
