## 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.

## The prompt

Fill in the parts in [square brackets], or leave them and the AI will ask you for them.

```text
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.
```

## Step by step

1. Save the image, video or audio clip you want to check
2. Open gemini.google.com and click Add files to upload it
3. Paste the prompt and send it
4. Read what Gemini found and what it couldn't confirm

## What you'll get

A plain answer on whether Google's AI watermark is in the file, which parts it covers, what a negative result doesn't prove, and three checks to do yourself.
