The Trust Gap
Your AI works. But how do users know? Metrics don't build trust—humans do.
Without HumanJudge
95% accuracy before deployment + irrelevant LLM benchmarks
Human validation: Blackboxed, model deployment driven
"How do I know this works?"
Trust gap: Users see only claims
With HumanJudge
95% accuracy
AI Reviewers: "100% correct"
"Real Human verified this."
Trust built: Public proof

Common Questions
What is Real-time HITL?
Human-in-the-Loop means real humans evaluate your AI outputs. Real-time means this happens continuously as outputs arrive — not one-time batch reviews.
How does this build trust?
Users trust humans over algorithms. Real-time HITL gives you public proof that verified experts continuously evaluate your AI — transforming claims into evidence.
Does this replace automated testing?
No. Real-time HITL complements automated metrics. Machines catch obvious failures; humans provide the trust layer users actually believe.
Who are the experts?
Verified domain professionals: doctors for medical AI, lawyers for legal AI, engineers for code. Credentials are public — that's how trust is built.
How does Langfuse integration work?
Outputs flow from Langfuse → evaluation queue → expert reviews → scores sync back to your dashboard automatically.
