Google $GOOGL is expanding its SynthID digital watermarking and content verification tools to Google Search and the Chrome browser, the company said at its annual I/O developer conference. Users will be able to check whether an image, video, or audio file was generated by AI through Search features including Lens, AI Mode, and Circle to Search, as well as through Gemini in Chrome.
SynthID verification is available in Search starting Tuesday. The Chrome rollout is expected over the coming weeks, the company said. A query such as "Is this made with AI?" or "Is this AI generated?" will trigger the verification check.
The announcement builds on an existing capability in the Gemini app, where SynthID verification for image, video, and audio has been used 50 million times globally since its introduction, the company said. Launched three years ago, SynthID works by embedding imperceptible signals directly into AI-generated content. To date, the technology has been applied to over 100 billion images and videos, along with audio totaling 60,000 years in length, according to Google.
Alongside SynthID, Google is also adding verification for C2PA Content Credentials — an industry standard that documents how media was created or modified — to its products. Gemini app users gain access to C2PA verification on Tuesday, while Search and Chrome are expected to follow in the months ahead. Having debuted Content Credentials support in the Pixel 10's camera app, Google is now widening that integration to include video recording on Pixel 8, 9, and 10 devices, a change expected in the coming weeks.
Among the new partners adopting SynthID are OpenAI, Kakao, and ElevenLabs, a move that extends the watermarking framework to platforms outside Google's ecosystem. In a statement quoted by Mashable, OpenAI described the pairing as mutually reinforcing: "These two systems reinforce each other. C2PA helps content carry detailed context; SynthID helps preserve a signal when metadata does not survive."
A new AI Content Detection API, offered through Google Cloud's Gemini Enterprise Agent Platform, is also being introduced to give organizations tools for spotting AI-generated media regardless of which model produced it. The company said it is launching the API with a group of trusted partners and will refine it based on their feedback.
Instagram will also gain the ability to recognize and label Content Credentials embedded in media shot on Pixel devices, giving creators a way to establish the authenticity of their posts on the platform. Both Google and Meta $META are members of the C2PA steering committee.
Broader accessibility is the driving ambition behind the expansion, according to Google CEO Sundar Pichai. "We want to make sure more people have easy, seamless access to these tools."
