Google launched a new website on Tuesday that anyone can use to verify whether a piece of media content – whether it’s a picture, video, or audio clip – was generated by AI.

Last year, Google provided this tool for testing to some journalists, media professionals, and researchers on Google I /O, and now it is open for everyone to use.

The website supports multiple formats: images include JPG, JPEG, PNG, BMP, WEBP, AVIF, HEIC, HEIF, TIFF, TIF, and GIF; videos include MP4, MOV, and WEBM; audio includes WAV, MP3, OGG, FLAC, AAC, and M4A.

Google uses SynthID, a technology that was introduced in 2023 to identify whether media is generated by AI. Google's Nano Banana, Veo, and Lyria models, as well as tools with generative capabilities such as Gemini, Flow, ProducerAI, and Vids, will all add watermarks to any media generated by SynthID.

OpenAI, NVIDIA, and Kakao also support SynthID, while OpenAI still maintains its own content verification website. Reports indicate that Apple is also set to join in supporting it as well.

Google has embedded the SynthID verification function into the Gemini app and Google Chrome. The company stated that currently, people initiate 1 million content verification requests per day.

Microsoft and Meta also have their own content watermarks and verification standards. However, these tools are not foolproof and often cannot identify content generated by their own models.
