Getting Started ​

Google SynthID is a digital watermarking tool developed by Google DeepMind. It embeds invisible watermarks into content generated by Google AI models, allowing you to verify whether images, videos, or audio were created by Google AI.

What You Can Do ​

  • Verify images for SynthID watermarks using the Gemini App on computer, Android, or iPhone
  • Verify videos up to 90 seconds long to check for AI-generated content
  • Verify audio files up to 1 hour long for embedded SynthID watermarks
  • Use alternative methods when SynthID results are unclear — visual artifacts, reverse image search, metadata analysis
