What happened
SEJ (2026-10-07): Google DeepMind opens SynthID Detector globally in English at synthid.com—checks image/video/audio for SynthID watermarks from Google and partners (incl. OpenAI, NVIDIA, Kakao). Explicitly not a general AI detector.
Why it matters
Content ops / trust: verify campaign assets before publish. Does not change Search ranking systems by itself.
