Google launched a web-based SynthID Detector that anyone can use to identify AI-created and AI-edited images, videos, and audio. Google says more than 180 billion pieces of content carry SynthID watermarks.

AI brief

Google's SynthID watermark detector is now publicly available, letting anyone check whether images, videos, or audio were created by Google's AI or partners such as OpenAI and Nvidia. Google says more than 180 billion pieces of content already carry the watermark.

Why it matters: It gives the public a way to check whether content was AI-generated, though the text notes the tool's coverage is limited.
