## Summary

Previously, users had to rely on Gemini for detection, which was cumbersome and limited to Google’s own watermarks. The new tool at [SynthID.com](https://synthid.com) supports watermarks from partners like OpenAI, Nvidia, Kakao, and soon Apple, though it only returns a yes/no result rather than detailed analysis.

Google reports SynthID has been embedded in over 180 billion images and videos and 240,000 years of audio from its Gemini models alone. The update aims to simplify verification for users outside Google’s trusted program, though it lacks the granularity of internal tools.

## Key points

- SynthID.com now detects watermarks from Google, OpenAI, Nvidia, Kakao, and Apple’s AI systems
- Tool returns only a yes/no result, unlike Google’s internal tool that highlights watermarked regions
- Google claims 180B images/videos and 240,000 years of audio from Gemini use SynthID

## Why it matters

A unified detector for multiple AI providers could standardize watermark checks, but limited output may reduce its utility for forensic analysis.
