Know if a viral photo, clip or voice note was made by Google AI
Gemini can spot an invisible watermark inside a picture, video or voice clip and tell you if Google's AI made it.
Published . Steps as of October 2026.
How can I tell if a photo or video was made with AI?
Upload it to Gemini and ask "Is this AI generated?" As of October 2026, Gemini checks images, videos under 90 seconds and audio under an hour for Google's SynthID watermark and content credentials. A yes is strong evidence that Google's AI made or edited it. A no only means no Google mark was found, since other companies' AI may not leave one, so also look for the original source before you share.

Your prompt
Fill in your details. Skip any you like.
This AI can't be filled in from a link, so the button copies your prompt: paste it into the new chat.
The prompt that gets copied
I've attached [WHAT IT IS, e.g. a video clip a relative forwarded me]. I saw it [WHERE YOU SAW IT, e.g. in a family group chat]. Please check whether this was created or edited with Google AI, using any SynthID watermark or content credentials you can detect. Tell me in plain words: what you found, which parts of the file it applies to, and how sure you are. Then be honest about the limits: if you find nothing, explain what that does and doesn't prove, since other AI tools may not leave a mark you can read. Finally, give me three simple things I can check myself before I share it or believe it, like looking for the original source.
Upload a suspicious image, short video or audio clip to Gemini and ask if it's AI generated. Gemini checks for Google's hidden SynthID watermark and content credentials, then explains what it found.
