Google DeepMind said on Oct. 7 that SynthID Detector, its tool for checking AI-generated media, is now available to all users through a standalone website. The service lets people upload images, videos, or audio files to see whether they were created with AI tools from Google or partner companies including OpenAI, NVIDIA, and South Korea’s Kakao. Apple is also set to join soon. According to an official blog post by Pushmeet Kohli, vice president of science and strategic initiatives at Google DeepMind, SynthID was introduced in 2023 to embed invisible digital watermarks into AI-generated images, video, and audio. Google said more than 180 billion images and videos have already been marked with SynthID, along with audio whose total duration equals 240,000 years. The company added that verification features built into Google Search, the Gemini app, and Chrome now handle more than 1 million queries a day. The detector is not a general-purpose AI checker. Google said it can only identify content generated by participating companies’ tools when that content carries a SynthID watermark. If media was made by other models or heavily modified, the result may show no detection. MacRumors also reported that users must sign in to use the site and noted the tool cannot tell whether content was fully generated by AI or merely edited with AI.

SynthID has been applied to more than 180 billion images and videos

In an official blog post, Pushmeet Kohli, vice president of science and strategic initiatives at Google DeepMind, said SynthID is a technology Google launched in 2023. It embeds invisible digital watermarks into AI-generated images, video, and audio.

Google said more than 180 billion images and videos have already been marked with SynthID watermarks. It also said the total amount of watermarked audio now equals 240,000 years in duration. Verification features built into Google Search, the Gemini app, and Chrome process more than 1 million queries each day.

Standalone website is live, with English-only interface for now

The newly opened version is a standalone website and currently supports only an English-language interface. According to MacRumors, users need to sign in before they can use it.

Supported file types include JPG, PNG, WEBP, and HEIC for images; MP4, MOV, and WEBM for video; and WAV, MP3, and FLAC for audio. For images, the detector checks whether a watermark is present. For video and audio, it highlights the segments that contain the watermark.

It is not a general AI detector

Google states on the detection site that SynthID Detector is not a general-purpose AI detector. It can only identify content generated by participating companies’ AI tools when that content carries a SynthID watermark. If the content was created by other models or has been heavily modified, the result may appear as not detected.

MacRumors also said the tool cannot distinguish between content generated entirely by AI and content that was only edited with AI.

OpenAI also moved on text watermarking earlier this week

On text watermarking, OpenAI said earlier this week that it had added watermarks to ChatGPT text outputs in the European Union. The company said it is using its own textGrain technology to meet labeling requirements under the EU AI Act.
