Google is expanding its SynthID verification tools to Search today, with Chrome support planned over the coming weeks. Users will be able to check the origin of images through Search features such as Lens, AI Mode, and Circle to Search.
The company is also launching an AI Content Detection API on Google Cloud, initially available to a group of trusted partners. Several companies are bringing SynthID watermarking to their AI-generated content, according to a blog post by Laurie Richardson, VP of Trust & Safety, and Pushmeet Kohli, Chief Scientist at Google Cloud and VP at Google DeepMind.
SynthID Verification In Search & Chrome
Google said it is expanding SynthID verification to Search today and plans to bring it to Chrome over the coming weeks.
Users can check whether an image was made with AI through features like Lens, AI Mode, and Circle to Search. You can ask questions like “Is this made with AI?” or “Is this AI generated?” to get verification results.
SynthID verification was already available in the Gemini app for images, video, and audio. It works by embedding imperceptible digital watermarks into AI-generated content.
C2PA Content Credentials
Google is also adding verification for C2PA Content Credentials, an industry standard for recording how media was created and modified.
The C2PA verification feature is rolling out in the Gemini app starting today and will roll out to Search and Chrome in the coming months.
AI Content Detection API
Google is launching a new AI Content Detection API on Google Cloud’s Gemini Enterprise Agent Platform, available to select partners. The API is a Google Cloud offering that Google says can detect AI-generated content made by Google and other popular models.
The API can help businesses evaluate and manage media across their platforms. Use cases include sorting feeds, preventing insurance fraud, fact-checking, and labeling synthetic media.
Initial partners include Shutterstock, Snap, Avid, Fox Sports, and Canva.
Industry Adoption Of SynthID
Companies including OpenAI, Kakao, and ElevenLabs are bringing SynthID technology to their AI-generated content. Google has open-sourced its SynthID text watermarking technology and partnered with NVIDIA to watermark AI-generated video from NVIDIA’s Cosmos models.
Meta, a fellow C2PA Steering Committee member, will start labeling camera-captured media with Content Credentials on Instagram. This means photos and videos shot on Pixel phones will be recognized and labeled on Instagram as camera-captured media.
Why This Matters
Google has been developing content-provenance tools since it first introduced SynthID in 2023. At that time, the technology was limited to select Google Cloud customers and was limited to images. The expansion to Search and Chrome moves verification from a specialized tool into surfaces where people encounter content every day.
The AI Content Detection API opens a different use case. Publishers and platforms that need to check whether content was made with AI will be able to access that capability through Google Cloud.
Searchers can already check image context through features like “About this image,” which Google expanded to Circle to Search and Lens in 2024. The SynthID verification adds a layer that checks for watermarks embedded at the point of creation, rather than relying on metadata that can be stripped.
The broader industry adoption of SynthID is worth watching. If more AI-generated media carries SynthID watermarks, Google’s verification tools have a wider base of content to check against. But SynthID only detects content watermarked with SynthID. Content from AI tools that don’t use it may not be identified through SynthID verification.
Looking Ahead
C2PA Content Credentials verification will come to Search and Chrome in the coming months. Google didn’t share specific timelines for broader availability of the AI Content Detection API beyond its initial partner group.
