# SynthIDDetector.org — agent index

SynthIDDetector.org is an independent tool that checks whether an image likely came from Google AI. It reads Content Credentials (C2PA) and AI metadata in the browser for free, and offers a sign-in pixel-level AI scan. It does not decode the SynthID watermark — only Google's detector (https://synthid.com) can do that.

SynthIDDetector.org is not affiliated with, endorsed by, or sponsored by Google or Google DeepMind. SynthID is a trademark of Google LLC.
