Google has expanded its SynthID Detector, now allowing anyone with internet access to scan images, videos and audio for concealed AI‑generated watermarks. The rollout, announced in a recent blog post, makes the tool globally available in English, moving beyond its prior limited release for media professionals.
**What does the SynthID Detector do?**
The detector checks whether a file carries a SynthID watermark, an imperceptible marker embedded by supported generative‑AI systems. By identifying these markers, users can determine if the content originated from Google or its partners, helping to verify authenticity.
**Who announced the expansion?**
Pushmeet Kohli, vice‑president of Science and Strategic Initiatives at [Google DeepMind](https://deepmind.com/), revealed the development in a blog entry. He emphasized that as AI tools become more accessible, clear context about digital media is essential for informed decision‑making.
**How extensive is the watermarking effort?**
Kohli noted that since introducing SynthID in 2023, Google has embedded watermarks in over 180 billion images and videos, plus roughly 240 000 years of audio content. The detector now supports content from Google and partner firms such as [OpenAI](https://en.wikipedia.org/wiki/OpenAI), [NVIDIA](https://en.wikipedia.org/wiki/NVIDIA), and [Kakao](https://en.wikipedia.org/wiki/Kakao), with Apple slated to join soon.
**Why is the tool important for Nigeria?**
In Nigeria, fabricated videos of public figures—including news anchors—have been used in financial fraud schemes. The broader availability of the SynthID Detector offers a practical means for individuals and regulators to spot manipulated media and curb its misuse.
Kohli summed up the initiative: “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.”
The detector complements verification features already present in Google Search, the Gemini app and Chrome, which together handle more than one million verification requests each day.
