Google originally launched SynthID, its digital watermark for AI-generated
content, as a way to detect whether an image was created using the company's
Imagen model in 2023. Now, at Google I/O 2025, the company is introducing a
public-facing tool called SynthID Detector that claims to detect those
watermarks in just about anything you upload.

SynthID Detector will be available as a web portal where you can upload
images, video, audio and text to be scanned. Once uploaded, SynthID Detector
Google claims the portal can tell you whether your upload contains AI-
generated material and even "highlight specific portions of the content most
likely to be watermarked." For audio, the tool is supposed to be able to
identify a specific portion of a track that contains the watermark, too.

SynthID was designed to mark content from Google's models but Google hopes
other companies will adopt the watermark for their own AI output. An open
source version of SynthID is already available for text watermarking, and as
part of the rollout of SynthID Detector, Google is partnering with NVIDIA to
mark media its NVIDIA Cosmos model generates. SynthID Detector won't be the
only tool that can spot Google's watermark, either. The company says GetReal
Security will also be able to verify if media contains SynthID.

Considering the sheer number of ways Google hopes people will using AI to
create images, video, text and audio, from the Audio Overviews in NotebookLM
to short films made with its new Flow tool, it makes sense that it would
offer a way to know if any of those things are real. Until models from one
company produces the vast majority of content or a digital watermark reaches
widespread adoption, though, a tool like SynthID Detector can only be so
useful.

Journalists, researchers and developers can join a waitlist to try SynthID
Detector through Google's online form.
