In Short: Google has launched a new website, SynthID Detector, which allows users to verify if media content was created using artificial intelligence (AI).

Google has launched a new website, SynthID Detector, which allows users to verify if media content was created using artificial intelligence (AI). The tool, previously available only to media professionals, is now accessible to everyone.

The SynthID Detector can identify media generated using AI from Google, OpenAI, NVIDIA, Kakao, and soon, Apple. Users can upload a photo, video, or audio file to determine if it contains a SynthID watermark, indicating it was created with AI.

According to Google, the watermarks are imperceptible to the human eye but can be detected by the SynthID Detector. The tool is integrated into Google's Search, Gemini, and Chrome, providing an alternative to the website.

Google's SynthID technology is designed to watermark content created by AI, making it easier to track and verify. However, the tool cannot distinguish between AI-created and AI-edited media, and it requires users to sign in to use it.

Google says its SynthID Detector is not a general AI detector but can only identify media that uses the SynthID technology. The company has integrated SynthID into its latest creative AI tools, such as Veo 3, which can generate synchronized audio.

Google claims that Gemini alone has integrated SynthID with over 180 billion images and videos, plus 240,000 years of audio. The company also plans to extend SynthID's reach by partnering with NVIDIA to mark media from the NVIDIA Cosmos model.

Despite these efforts, the tool is not infallible and may sometimes fail to identify content created by its makers' models. Google engineers have told Ars Technica that limiting access is necessary to prevent people from using the checks to develop SynthID removal tools.

Author Joanna Maciejewska expressed a sentiment captured by WinBuzzer, saying, “I want AI to do my laundry and dishes so that I can do art and writing, not for AI to do my art and writing so that I can do my laundry and dishes.”

What this adds

Google's SynthID Detector is now available worldwide in English, and it includes a daily usage quota of approximately 10 image, video, and audio checks.

The SynthID Detector is Google's response to the rapid increase in AI-generated content, which raises concerns about deepfakes and misinformation.
