At Google I/O 2025, Google introduced SynthID, a new tool designed to identify content created by its AI model, Gemini. As AI-generated text, images, and videos become more common, it’s important to know when something is made by a machine. SynthID works by embedding a unique digital signature in AI-generated content, helping users and platforms spot and verify what comes from Gemini.
This development aims to bring more transparency and trust to online content, especially as AI tools grow smarter and more widespread. Google hopes SynthID will help prevent misuse of AI-generated media and support efforts to keep digital spaces honest and safe for everyone.
