Google SynthID watermark helps debunk AI-generated McConnell image
11 reported
Google’s SynthID system was used to debunk a high-profile AI-generated hoax image of Senator Mitch McConnell, according to a TechCrunch report. A picture circulated online earlier this week appearing to show McConnell covered in tubes in a hospital bed in extreme distress. The image was shared widely on Reddit and X. By Wednesday, fact-checking site Snopes debunked the image, noting it registered as containing the SynthID watermark designed by Google to identify AI-generated pictures. The watermark worked as intended in what the report described as a win for anti-deepfake technology. McConnell’s health has been the subject of intense speculation since he checked into the hospital after an emergency call on June 14, and he has been largely absent from the public eye. In this case, the evidence proved to be entirely fake.

Snopes debunked the image, noting it contained the SynthID watermark.
SynthID is an invisible signature visible to SynthID algorithms but unnoticeable to casual observers.
The watermark survives screencaptures across multiple platforms.
SynthID can only be used when an image-generation tool participates in the program.
Gemini models have included the watermark since the program launched in 2025.
OpenAI joined the program in May 2026.
Anthropic does not participate in the program.
Users can check images by asking a Gemini model or uploading to OpenAI’s public image verification tool.
