Trust OS: Responsible AI powered by observability, oversight, and control.

BuildBuild with confidence and ease. Design, test, and launch your AI agent in days, not months, using tools that simplify every step.
TestValidate early, before it matters. Detect, analyze, and fix potential issues long before they impact your customers.
EvaluateStay in control, always. Monitor results in real time, measure impact, and continuously optimize your business performance.

See inside every conversation. Everything is logged and easy to trace.

Stay in control of what your AI says and does.

Review & grade responses

Every response gets a quality score. Flag outliers, surface patterns, and grade against your standards — without reading every conversation manually.

Hallucination & unsafe content detection

Detect factual errors, off-policy responses, and safety violations automatically. Know about it before your customers do.

Kill switch & escalation controls

Pause, redirect, or kill any AI flow instantly. One-click escalation to a human agent — with RBAC so the right people own the right agents.

Stay in control of what your AI says and does

Every change tested before it touches a customer.
business outcomes

Staging, real-conversation test suites, gradual rollout, and A/B data — so every deploy comes with evidence, not faith.

Staging environments

A production mirror with real integrations and policies. Catch issues early, before they reach customers.

Gradual rollout & A/B testing

Ship to 10% first. Run two versions head-to-head. Get hard data on resolution rate and CSAT before you commit to either.

Test Upgrade

Run real conversations through your new version. Catch issues early, before full release.

With zero-touch improvement, your AI keeps getting better while you sleep.

Observability catches the issue, Control tests the fix, and Oversight keeps everything on policy. ZTI runs the whole loop for you.
