AI Checker: Google SynthID Detector
Need an AI check for a photo, video or audio clip? This AI Checker guide shows how to look for invisible watermarks using Google's official SynthID Detector. A watermark check can help identify supported AI-generated or edited media, but cannot prove that every other file is genuine.

NVIDIA
Detection applies to supported SynthID-enabled models and products. Not every AI-generated file from these companies contains a SynthID watermark.
How Does SynthID Watermarking Work?
SynthID embeds invisible digital signals into supported AI-generated content to help identify its origin.
Invisible Digital Watermarks
SynthID embeds digital signals directly into AI-generated images, audio and video. These watermarks are designed to be imperceptible to people viewing or listening to the content.
Resistant to Common Editing
SynthID watermarks are designed to survive common changes such as compression, filters and certain media edits. Significant modifications may still reduce detection accuracy.
Not a Universal AI Detector
SynthID searches for its supported watermark signal. It cannot automatically identify every AI-generated image, video or audio file from every AI company.
How to Use the Google SynthID AI Checker
Check supported AI-generated media in three simple steps.
Open Google Detector
Click the button on NumGenie to visit Google's original SynthID Detector website.
Upload Your Media
Select an image, video or audio file on Google's website. Use the highest-quality original file available.
View Detection Results
Google checks for supported SynthID watermarks and displays the detection result.
Understanding AI Check Results
Learn what Google's watermark detection results actually mean.
β Watermark Detected
A SynthID watermark was detected in the uploaded media. This indicates that the content was likely generated or edited using a supported AI model.
β Watermark Not Detected
No confident SynthID watermark was detected in the file. This does not prove that the content is authentic or human-created.
AI Checker Frequently Asked Questions
What is SynthID?
SynthID is a digital watermarking technology developed by Google DeepMind.
It embeds invisible digital watermarks into supported AI-generated images, videos and audio.
SynthID also includes separate watermarking technology for AI-generated text.
Why was SynthID created?
SynthID was created to improve transparency around AI-generated digital content.
As AI becomes more advanced, generated images, videos and audio can look and sound increasingly realistic.
SynthID helps people identify content generated or edited using compatible AI systems.
How does watermarking work?
When a compatible AI model generates content, SynthID embeds a digital watermark into the generated media.
For images and videos, the technology works with visual information.
For audio, it embeds a signal designed to be inaudible to listeners.
A compatible detector can later analyze the content and identify the hidden signal.
Which AI models and products use SynthID today?
Google uses SynthID across selected AI generation products and models.
Partners adopting SynthID technology include NVIDIA, OpenAI and Kakao.
Support depends on the individual product, model and content type.
Not every AI-generated file from these companies contains a SynthID watermark.
What types of content can the SynthID Detector analyze?
The public Google SynthID Detector supports three main media categories.
Images: Checks for invisible SynthID watermarks in supported image files.
Videos: Checks videos and may identify watermarked segments.
Audio: Checks compatible audio recordings, including AI-generated speech and music.
Text watermarking is separate from this public media upload detector.
How do I interpret detection results?
Watermark detected: A recognized SynthID watermark is present in the file.
This suggests the content was generated or edited using supported AI technology.
Watermark not detected: No confident SynthID watermark was identified.
A negative result does not confirm that the content was made by a human.
What is the difference between SynthID and AI detection tools?
SynthID searches for digital watermarks intentionally embedded during supported AI content generation.
General AI detection tools often examine patterns in content and estimate whether AI may have been involved.
SynthID checks for a specific watermark signal, while general AI detectors often use predictive analysis.
How robust is image, audio and video watermarking?
SynthID is designed to survive many common digital media transformations.
Examples include compression, certain filters, colour adjustments and some audio or video modifications.
However, no watermarking system can guarantee detection after every possible edit.
Significant changes to the original media may reduce detection reliability.
Why isn't there one universal watermarking standard for all AI companies?
Different AI systems generate different types of content.
Images, videos, audio and text each have different technical requirements for watermarking.
Developing a universal standard requires cooperation between AI companies, technology providers and standards organizations.
Digital watermarking and content provenance systems can work together to improve transparency.
