Why we stand out:

  • Our best-in-class accuracy is derived from our sole, research-backed mission and use of multiple models per modality

    We can detect AI-generated fraud and disinformation in near- or real time across all modalities including audio, video, image, and text.

    Our platform is designed for ease of use, featuring a versatile API that integrates seamlessly with any system, an intuitive drag-and-drop web application for quick ad hoc analysis, and platform-agnostic real-time audio detection tailored for call center deployments.

    We’re privacy first, ensuring the strongest standards of compliance and keeping customer data away from the training of our detection models.
