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.

Track, evaluate, and ship AI models and agents in one connected environment.
Log metrics, losses, and media from training runs and compare them side by side in interactive charts to spot what actually improves your model.
Run automated hyperparameter sweeps and visualize parameter importance so you can converge on better configurations faster.
Version datasets and model artifacts, track lineage, and promote models through a registry from training to production.
Build, log, and evaluate LLM prompts and applications, with tracing and evaluation tools grouped under an LLMOps workflow.
