Google opens SynthID AI-content detector to the public, covering watermarks from Google and partners

Overview

AISummary of 14 articles

Google has opened its SynthID Detector to anyone at SynthID.com, letting users upload or paste an image, video, or audio file to check for a SynthID watermark from Google or partners OpenAI, NVIDIA, and Kakao, with Apple support coming soon.

Users must sign in with a Google, Apple, or OpenAI account, and Google says uploaded files are deleted right after scanning, a claim a Google Chrome-linked poster on X made. Google says SynthID has watermarked over 180 billion images and videos.

The tool only detects SynthID watermarks, so it misses AI content without them, such as output from Anthropic's Claude, xAI's Grok, and open-weights Chinese models. SiliconANGLE reports it cannot identify which parts of edited content are AI-made. Gizmodo's tests found Gemini and Grok gave inaccurate or unsupported answers about AI images and advises against treating results as definitive, while Ars Technica notes it did not independently verify how completely the detector finds watermarked content.

    Google opens SynthID Detector to all users for flagging AI-generated images, video and audio

    AIGoogle has launched SynthID Detector, a web-based tool anyone can use, after signing in with a Google, OpenAI or Apple account, to identify AI-generated images, video and audio.
