What is SynthID?

SynthID is a suite of tools from Google DeepMind for watermarking and identifying AI-generated content. It embeds imperceptible digital watermarks into images, text, audio, and video produced by AI models. These watermarks survive common modifications like cropping, filtering, and compression, allowing reliable detection later.

SynthID is already integrated into Google products like Imagen and Gemini, and an open-source text watermarking toolkit is available for developers. It's designed for creators, platforms, and organizations that want to maintain transparency about AI-generated content without degrading quality.
