Google makes its SynthID Detector available worldwide, allowing users to check images, videos and audio for signs of AI-generated content.
Google has expanded access to its SynthID Detector, allowing people worldwide to check images, videos and audio files for signs of AI-generated content.
Pushmeet Kohli, vice president of Science and Strategic Initiatives at Google DeepMind, announced the development in a blog post. The tool, previously available in an early version to media professionals, is now accessible globally in English.
The detector allows users to check whether images, videos and audio contain SynthID watermarks in supported AI-generated content from Google and partner companies, including OpenAI, NVIDIA and Kakao. Apple is expected to join the initiative soon.
The expansion comes as technology companies develop tools to help users establish the origins of digital content as generative AI becomes more widely used.
Google said the wider access is intended to help people make informed decisions about the media they encounter online.
“As AI tools become better and easier to use, having clear context about the content you encounter online helps you make informed decisions about what to trust,” Kohli said.
Kohli said Google had been using SynthID to help identify AI-generated media since introducing the technology in 2023.
“To date, we’ve watermarked over 180 billion images and videos, along with 240,000 years of audio content,” he said.
SynthID works by embedding imperceptible watermarks in supported AI-generated images, videos and audio files. The detector allows users to check whether a file contains a SynthID watermark, helping them establish whether the content carries the technology’s identifying markers.
“With the new SynthID Detector, anyone can easily check if an image, video, or audio file was made with AI from Google or our partners, including OpenAI, NVIDIA, Kakao, and soon, Apple,” Kohli said.
Google introduced an early version of the detector last year to help media professionals verify AI-generated content. The latest expansion makes the tool available to the wider public.
The detector complements verification features available through Google Search, the Gemini app and Chrome. Google said the services collectively handle more than one million requests daily.
The expansion comes as concerns grow over the use of synthetic media to impersonate individuals, spread misleading information and facilitate online fraud.
In Nigeria, fabricated videos of public figures including ARISE News anchors have featured in financial scams, highlighting the risks posed by manipulated digital content. Regulators and technology companies are exploring ways to identify such material and protect individuals from its misuse.
