Control Every AI Decision
Your Organisation Makes
LLM observability, prompt CI/CD, and EU AI Act compliance — in one platform.
Works with your stack
THE PLATFORM
Three Products. One Data Model.
LLM Observability
StackTrace
Know exactly what your AI did, why, and whether it was good — in real time.
Explore StackTrace →Prompt Management
FlowOps
Ship prompts like code. Version, promote, and A/B test across every environment.
Explore FlowOps →AI Governance
GovernAI
Govern with confidence. Policies, audit trails, and EU AI Act compliance reports — in one click.
Explore GovernAI →THE PROBLEM
Sound Familiar?
Prompt chaos
Prompts buried in code, no versioning, no safe rollout — one bad edit breaks production at 2am.
No audit trail
Can't prove to regulators what your AI touched, when, or what it returned. Auditors have questions you can't answer.
.NET ignored
Every observability tool built by Python devs, for Python devs. Your .NET team is left writing custom integrations.
PLATFORM OVERVIEW
