Google rolls out improved SynthID AI content detector, now available globally
Summary
Google expanded its SynthID AI content detector to recognize watermarks from multiple partners beyond its own Gemini, making it easier to verify AI-generated media. The new detector is available via SynthID.com with login-based access and a daily usage quota, and supports detectors from Google, OpenAI, Nvidia, Kakao, and soon Apple. The article notes limitations (not all AI content is watermarked) and suggests cryptographic labeling as a potential future improvement.
