Enterprise AI and plagiarism detection for content integrity
Identifies AI-generated text across 30+ languages and leading LLMs, with reported accuracy above 99% on internal English test sets.
Searches 60 trillion websites, 16,000+ open-access journals and internal repositories to catch paraphrasing and hidden copying.
Extends detection to AI-generated video, audio and images so teams can verify content beyond text alone.
A scalable API and workflow integrations automate content analysis inside LMS platforms, publishing tools and enterprise systems.

On-premises biometric identity verification SDKs
Face recognition, face liveness, deepfake detection, ID document recognition, ID liveness, and a combined eKYC suite — pick only what you need.
Server SDKs run on your own Linux hardware or private cloud via Docker, with air-gapped and VPC-friendly options and no per-call charges.
iOS, Android, Flutter, and React Native SDKs run matching and capture locally, including offline, so nothing is uploaded.
Layered passive and active liveness plus deepfake detection help stop presentation attacks and synthetic media.
