It's a simple way to check whether an image has been created or manipulated, with a few caveats.
Key facts
- Meta embeds its own watermark, called Content Seal, into its AI creations and offers a web-based detector tool, though a 2026 report from Reuters found that it sometimes failed to accurately spot them
- In 2025, it launched a limited version of SynthID Detector for certain researchers and journalists, and now it's available for everyone
- A Google spokesperson reportedly told Ars Technica that users are limited to around 10 checks per day to prevent them from using the detector's output to find a way to remove SynthID
- Google introduced SynthID in 2023, which adds an imperceptible label to AI-generated content, but there was no way for regular users to check for one until now
Summary
With the proliferation of generative AI tools pumping out images, videos and even songs in recent years, it's hard to spend time on the internet without wondering whether what you're seeing or hearing is real. Google introduced SynthID in 2023, which adds an imperceptible label to AI-generated content, but there was no way for regular users to check for one until now. Since the launch of SynthID, Google's Gemini AI model has embedded a watermark in everything it creates. That's a big improvement over Google's previous process. That means the new tool can tell whether media was made with AI models from OpenAI, NVIDIA and Kakao, in addition to Gemini.
