Google opens SynthID Detector to everyone for checking AI watermarks

Google has made its SynthID Detector publicly available at SynthID.com, letting anyone upload an image, video or audio file to check for the invisible SynthID watermark. The tool recognizes content from Gemini and partner models including OpenAI, Nvidia and Kakao, with a limit of about 10 checks per day and a required Google, OpenAI or Apple login.

• Checks run on SynthID.com after logging in with Google, OpenAI or Apple
• Users are limited to roughly 10 checks per day to protect watermarks
• Detects marks from Gemini, OpenAI, Nvidia and Kakao; Apple support pending
• Media without SynthID, such as Meta's AI output, is not detected
