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.
Real-time multi-modal content moderation for text, images and video
Screens text, images and video through one platform so a single set of policies can cover every content type you host.
Content is evaluated on submission so violations can be blocked or flagged before they go live, rather than in a nightly batch.
Detects policy-violating material such as abuse, unsafe imagery and other categories you need to keep off your platform.
Dedicated detectors for written content and visual content let you tune sensitivity per medium instead of forcing one threshold on everything.
