According to @GeminiApp on Twitter, Google has integrated a powerful AI-generated content verification tool into the Gemini app, allowing users to upload images or videos to detect if they were created or edited with Google AI via the SynthID watermark (source: @GeminiApp, Dec 18, 2025). This enables businesses and content creators to easily identify AI-generated media, strengthening trust and transparency in digital content. The practical application of SynthID within Gemini is significant for industries such as media, advertising, and online platforms seeking reliable AI content detection solutions.
