Google has expanded global access to its AI content verification tool, SynthID Detector, enabling users around the world to check images, videos, and audio files for signs of artificial intelligence-generated content.
The announcement was made by Pushmeet Kohli, Vice President of Science and Strategic Initiatives at Google DeepMind, who disclosed in a blog post that the detector, previously available only to selected media professionals in an early-access phase, is now accessible globally in English.
The SynthID Detector is designed to identify digital content embedded with SynthID watermarks, a technology developed by Google to help distinguish AI-generated media from human-created content. The tool supports content generated by Google and partner companies, including OpenAI, NVIDIA, and Kakao, while Apple is expected to join the initiative in the near future.
According to Google, the move is aimed at improving transparency online and helping users make informed decisions about the content they encounter as generative AI tools become increasingly widespread.
“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.
Google introduced SynthID in 2023 as part of efforts to address growing concerns about misinformation, digital deception, and the misuse of AI-generated media. Kohli revealed that the technology has already been used extensively across Google’s AI ecosystem.
“To date, we’ve watermarked over 180 billion images and videos, along with 240,000 years of audio content,” he said.
The technology works by embedding imperceptible digital watermarks into supported AI-generated images, videos, and audio files. When a file is uploaded to the SynthID Detector, the system analyzes it to determine whether the watermark is present, helping users verify the content’s origin.
“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 added.
Google first rolled out an early version of the detector last year to support journalists and fact-checkers in verifying AI-generated content. The latest expansion extends access to the general public.
The detector complements other verification and transparency tools available across Google products, including Google Search, the Gemini app, and the Chrome browser. Google said these services collectively process more than one million verification-related requests each day.
The global rollout comes amid growing concerns over the use of synthetic media for impersonation, misinformation campaigns, and online fraud.
In Nigeria, manipulated videos featuring public figures and media personalities, including presenters from ARISE News, have reportedly been used in financial scams and deceptive online schemes, underscoring the need for stronger tools to identify and authenticate digital content.
As governments, regulators, and technology companies seek solutions to combat the misuse of AI-generated media, Google says the wider availability of SynthID Detector represents a significant step toward improving transparency and trust in the digital information ecosystem.
