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.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
