Google expands public access to SynthID Detector

What happened

Google announced wider SynthID Detector access on October 7, 2026, describing the tool as available globally in English. Its announcement links directly to the official detector.

The tool checks images, video and audio for SynthID watermarks from Google and participating partners, including OpenAI, NVIDIA and Kakao. Google listed Apple support as forthcoming. DeepMind explains that SynthID embeds an imperceptible signal in supported generated media.

How to read a result

This is a check for a particular provenance signal, not a universal AI detector or a verdict that a scene is true. No detected watermark does not prove human authorship. The announcement’s scope should not be stretched to every file from every AI tool.

The public detector page did not expose usable account or quota information in this source check. No sign-in, upload or functional detector test was performed.

What to do with this

Editorial suggestion: Check provenance alongside the original uploader, date and independent reporting. Preserve the file and result if they matter to your work. Do not upload private or confidential media without permission, and avoid making accusations from a detector result alone.
