Google Opens SynthID Detector to Public
SynthID Detector is now publicly available but only identifies content from specific vendors.

Google launched the web-based SynthID Detector on October 7, making AI content verification tools available to the general public for the first time.
Previously restricted to journalists and media professionals, the new tool identifies images, video, and audio generated by models from Google, OpenAI, Nvidia, and Kakao. Users must sign in with a Google, OpenAI, or Apple account to access it.
A significant limitation is that it only detects content embedded with the invisible SynthID watermark. Major competitors like Anthropic’s Claude, xAI’s Grok, and many Chinese open-source models do not use this standard and will be missed. The tool also cannot distinguish between fully AI-generated content and AI-edited material, nor can it pinpoint which parts were modified.
Google states it is working to extend partnerships and advocates for industry-wide standards, but no universal solution currently exists.
