Google opens SynthID Detector to everyone

What is changing?

Google has expanded access to SynthID Detector after testing it with journalists and media professionals. Users can upload images, videos or audio at synthid.com to check for invisible watermarks from supported generation systems.

SynthID embeds an imperceptible signal during AI generation. Google DeepMind lists support from Google, OpenAI, NVIDIA and Kakao, while describing Apple support as forthcoming. The official video explains the technology.

A “watermark not detected” result does not prove that a file is authentic. Unsupported models, older content and heavy editing can produce that outcome. Google also notes rare false detections and recommends high-quality files and additional evidence.

AI Radar perspective: This adds a useful provenance check for design and video teams. Results should be assessed alongside the source and other evidence rather than treated as a standalone authenticity verdict.
