SynthID Detector, Google’s web tool for finding AI-generated or AI-edited content, is now available to all users. It works on images, video, and audio created with AI tools from Google, OpenAI, NVIDIA, and Kakao. The tool is free, and signing in with a Google, OpenAI, or Apple account is required.
The website will also be among the first AI detection tools to recognize images produced by Apple’s AI features, such as Image Playground. Google says support for images created and edited with Apple Intelligence is coming soon.
Google has worked on SynthID Detector for more than a year, with earlier versions available to journalists and other media professionals. Anyone can now visit synthid.com to check whether content has a SynthID watermark. Google also supports detection of SynthID watermarks and C2PA content credentials through Circle to Search and the Gemini app. A dedicated website makes these tools more accessible, particularly for people who don’t already use Google’s AI products.
Like other AI detection tools, SynthID Detector has limits. It can’t catch all AI-generated content because companies use different watermarking standards. Watermarks can also be removed in some cases. Google’s site doesn’t separate content made entirely by AI from content that was only edited with it, so it can’t say how a piece was produced or which parts may be synthetic.
SynthID Detector is a positive step, but verifying AI-generated content is still far from foolproof. Tools like it rely on a mix of different standards, so there is no universal checker. Meta, for example, has been testing its own web tool, which identifies images created or edited with its latest Muse Image models but not those from other companies or its earlier models.
Still, Google appears likely to bring more companies on board with SynthID over time. It said earlier that ElevenLabs had committed to supporting the watermarks. On its website, Google says it is continuing to expand its partnerships so the tool can detect more generated media.
