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.
The control plane for trusted enterprise agents and models
See the performance of every agent and predictive model in a single pane of glass, with every action, token and dollar traceable by user and team.
Fiddler Centor Models power policy enforcement and continuous evaluation inside your network, avoiding external LLM API calls and their hidden costs.
Detects and redacts PII, PHI and secrets on the same request path — before a prompt reaches the model and before a response reaches the developer — with sub-80ms latency.
Keeps a living inventory of every connected agent and records each enforcement decision, with who triggered it and what happened, ready for GRC and AI regulation audits.
Widely used for quick AI text detection, but less comprehensive for enterprise plagiarism and code auditing.
