SynthID Detector
Google's public tool for checking whether an image, video, or audio file carries a SynthID AI watermark, now open globally in English.
Overview
Google opened SynthID Detector to everyone globally in English on October 7, 2026, via the portal at synthid.com. The tool checks images, video, and audio for the invisible SynthID watermark embedded by Google and partner generators, including OpenAI, Nvidia, and Kakao, with Apple support to follow. Google states it is explicitly not a general AI detector: it can only identify media from systems that have adopted SynthID, not AI content in general. Since SynthID launched in 2023, Google says it has watermarked more than 180 billion images and videos and 240,000 years of audio content, and built-in SynthID checks in Search, the Gemini app, and Chrome now handle over 1 million requests daily.
