In December 2025, Google unveiled a cutting-edge AI video detection capability within its Gemini app. This new feature empowers users to ascertain whether a video was crafted using Google’s AI technology. Users can simply upload the video and input relevant prompts for verification. Built upon SynthID digital watermarking technology, this tool is currently tailored to recognize video content produced exclusively by Google’s own AI tools. It imposes certain constraints: the file size must not exceed 100MB, and the video duration is capped at 90 seconds.

Having previously been utilized for image detection, the extension of this technology to video verification signifies a significant leap forward in Google’s commitment to bolstering transparency in AI-generated content. Beyond the detection tool, the Gemini platform boasts a comprehensive creative suite, encompassing AI-driven drawing, video generation, and intelligent editing. This suite forms a seamless, end-to-end workflow, spanning from content creation to authenticity verification.

The introduction of this feature not only amplifies users’ capacity to discern AI-generated content but also reinforces the trustworthiness of the platform’s content ecosystem through advanced technological measures.
