Check an Image for SynthID

Use the checker for the provider that may have produced the file. Not detecting a signal does not establish that a human created it.

File is sent to OpenAI

Check with OpenAI

Use an original image to check supported provenance signals from OpenAI C2PA and SynthID. The checker does not identify all AI-generated images.

Check with Google

Use the signed-in Gemini app for Google's public SynthID verification. The file goes from you to Google and never travels through GeminiWatermarks.com.

In Gemini, upload one image and ask: “Was this image created or edited by Google AI?”

Google AI tools are the current source of SynthID signals recognized by Gemini. This is not an all-provider detector.

Image checking and removal stay separate, and processing never reacts to checker outcomes.
