Google has made SynthID Detector, its free web tool for identifying AI-created and AI-edited content, publicly available at synthid.com. The tool flags images, video and audio made with AI tools from Google, OpenAI, NVIDIA and Kakao, and support for Apple's Image Playground and Apple Intelligence is coming soon. It requires login via Google, OpenAI or Apple account. Limitations include inability to detect all AI content or distinguish fully created from merely edited media.
