About

Gretchen AI is a verification platform from Berlin for organisations that cannot afford to be wrong about what is real. It analyses images, video, audio and text in real time and detects more than 80 types of deepfakes and synthetic media. Detection alone is not enough. Gretchen AI also evaluates context and source credibility and examines metadata and provenance, because authentic material can mislead as well. Every result is explainable and ready for editorial or official use. Gretchen AI can be embedded into existing IT infrastructure and offers a social media integration, so content can be verified right where it spreads. The platform is GDPR-compliant and serves public authorities, security and defence, newsrooms and image agencies. Gretchen AI was used by the State of Berlin to help citizens check suspicious content during the 2026 Berlin state election.

About

NVIDIA Synthetic Video Detector is an AI-powered microservice designed to determine whether a video is real or AI-generated. It is optimized for content produced by diffusion models and built for media authentication, digital forensics, content verification, broadcast workflows, and media-integrity services. The model analyzes MP4 video input and returns a prediction for each frame on a scale from 0 to 1, where values closer to 0 indicate real footage and values closer to 1 indicate synthetic content. It is designed to remain robust under common video-compression conditions, helping preserve detection reliability when footage has been processed or distributed through typical media pipelines. It uses a Vision Transformer architecture based on an ensemble of DINOv2 and DINOv3 backbones, combining visual representations to distinguish authentic footage from generated video. Input frames are cropped to 504 x 504 pixels and normalized before inference.
