With AI tools becoming more powerful, creating realistic photos, videos, and even deepfakes has become easier than ever. As a result, it’s getting increasingly difficult to tell whether online content is real or AI-generated. From edited images to manipulated videos, misinformation can spread quickly if content is not verified.
To tackle this challenge, Google has introduced a Content Transparency feature through its Google Gemini app. This tool helps users identify whether an image or video was created or modified using Google’s AI tools.
How Google Gemini detects AI-generated content
Google uses a special watermarking technology called SynthID. This technology embeds hidden, invisible markers into AI-generated content. These markers cannot be seen by the human eye but can be detected by Gemini.
Using this system, users can check the authenticity of images, videos, and even audio files created with Google’s AI.
What you need
-
The Google Gemini app (latest version recommended)
-
The image or video you want to verify
This feature is available in supported countries and languages, making it accessible to users worldwide.
Step-by-step: How to verify photos and videos
-
Open the Google Gemini app on your phone.
-
Upload the image or video you want to check.
-
For videos, files can be up to 100MB in size and up to 90 seconds long.
-
-
Once uploaded, ask Gemini a simple question such as:
-
“Was this created using Google AI?”
-
“Is this image or video AI-generated?”
-
How Gemini gives results
Gemini scans the uploaded content for the SynthID watermark. It then uses its reasoning capabilities to explain what it finds.
For videos, Gemini can even identify specific sections where AI was used. For example, it may respond:
“SynthID detected in audio between 10–20 seconds. No SynthID found in visuals.”
This helps users clearly understand whether the entire content or only certain parts were created or altered using AI.
Why this matters
As AI-generated content becomes more common, tools like Google Gemini play a crucial role in fighting misinformation and deepfakes. By making content verification simple and accessible, Google is helping users make more informed decisions about what they see and share online.
