Google's Circle to Search feature can tell you if an image was AI-generated

What is SynthID?

SynthID is Google’s proprietary watermarking system that embeds invisible metadata in content created or modified with its own AI tools.

• A dedicated SynthID detector was announced at I/O last year.
• The detector was later integrated into the Gemini app.

New Capabilities in Chrome and Search

With the update, users can assess an image’s origin through several methods:

• Circle to Search on Android can now flag AI‑generated content.
• Google Lens and Chrome’s Gemini integration can answer queries such as “Is this AI generated?”
• The tools can provide granular details, e.g., indicating that an image was captured on a Pixel phone and later edited with AI tools in Google Photos.

Limitations

• Granular detail is only available for images captured or edited with Google’s own tools.
• Images originating from other AI platforms may not be reliably flagged.
• Content credentials (an industry‑standard watermarking system) have been added to the native camera app in the Pixel 10 lineup and are now expanding to Pixel 8 and 9 models.

Industry Adoption

Google notes that OpenAI, Kakao, and ElevenLabs have committed to bringing SynthID technology to more of their AI‑generated content.

• OpenAI plans to integrate SynthID with images created via ChatGPT, Codex, or the OpenAI API.
• The Gemini app will receive content‑credential support today, with Chrome and Search integrations expected in the coming months.

Challenges and Outlook

No watermarking system is foolproof. Researchers have demonstrated ways to evade detection:

• Researchers tested AI watermarks and broke all of them
• Methods to remove watermarks and deepfakes

Despite these challenges, providing users with tools to verify the provenance of images is a valuable first step as AI‑generated content becomes increasingly convincing and ubiquitous.
