AI governance, testing, and observability for regulated enterprises
Dozens of pre-built evaluations cover quality, safety, security, and performance, with LLM-as-a-judge scorers, session-level metrics, and support for writing your own custom tests against your own data.
Import a repository and run evaluation suites automatically on every change, benchmark each iteration, and block releases when a metric regresses beyond the threshold you define.
Trace every request through multi-step agent workflows, including tool calls and retriever steps, with token counts, latency, cost per request, alerting integrations, and subpopulation analysis.
Register each AI system with an owner, purpose, data sensitivity, and risk tier, score inherent risk across multiple dimensions, and move systems through staged approval gates before they reach production.

The control layer for conversational and agentic AI
Define the policies an AI must follow and have them enforced at runtime rather than hoped for in a prompt.
Detect frustration, hesitation, risk and changing intent so an agent adapts instead of replying on autopilot.
Constrain which tools and actions an autonomous agent may take, and when it must escalate instead.
Record which policy governed each interaction, why an action was allowed, and what triggered an intervention.
