Overview
- Users can upload a photo in the Gemini app and ask if it was AI‑generated to check for Google’s SynthID watermark.
- The launch covers images only and can currently confirm content created or edited by Google’s own tools that embed SynthID.
- Google says support for verification of video and audio is coming next, with plans to bring the capability to surfaces such as Search.
- Images produced by the new Nano Banana Pro model in Gemini, Vertex AI and Google Ads now carry C2PA metadata for traceable origins.
- Independent research has shown watermarks and metadata can be stripped or defeated, reinforcing calls for automated platform‑level flagging rather than manual checks.
