Google has finally open-sourced SynthID Text, which is its watermarking and detection tool for AI-generated text.

Developers can now use Google’s SynthID Text technology to determine whether text was made by their own AI models.

The move gives the entire AI industry an easy, seemingly robust way to silently mark content as artificially generated, which could be useful for detecting deepfakes and other damaging AI content before it goes out in the wild.

Google’s SynthID text watermarking technology, a tool the company created to make AI-generated text easier to identify, is now available open-source through the Google Responsible Generative AI Toolkit, the company announced on X.

Google is making SynthID Text, its technology that lets developers watermark and detect text written by generative AI models, generally available. SynthID Text can be downloaded from the AI platform Hugging Face and Google’s updated Responsible GenAI Toolkit.

It’s much easier for AI to fake text than it is for audio, images, or videos. As such, watermarking said content seems like an impossible task. However, it seems that Google has a solution in the form of the SynthID Text tool.

The company conducted a massive experiment on its watermarking tool SynthID’s usefulness by letting millions of Gemini users rank it.

Google's DeepMind division has announced a watermarking tool focused on detecting AI-generated text with high accuracy.
