watermarking over 100 billion images and videos and 60,000 years of audio
In an era of generative media, we believe that identifying authentic, unedited content can be just as important as knowing when a file was made or edited using AI.
More content across the web will soon carry these imperceptible watermarks, as companies like OpenAI, Kakao and ElevenLabs are bringing SynthID technology to more of their AI-generated content.
