What is changing?
Google opened SynthID Detector to everyone worldwide on October 7 after previously testing it with media professionals. The English-language portal checks uploaded images, video or audio files for SynthID, Google's imperceptible watermark.
Coverage is not limited to Google output. According to the announcement, the detector can also check content watermarked by OpenAI, NVIDIA and Kakao, with Apple support coming soon. Google says its built-in verification features across Search, Gemini and Chrome now handle more than one million requests per day.
The result does not definitively prove whether a file is generally AI-generated; it looks for a SynthID signal added by supported providers. An absent watermark therefore does not mean the content was made by a person. For creative teams, the portal adds one more provenance signal to pre-delivery checks.
