Humanlayer ai
The Human QA Layer for AI Startups
We evaluate LLM outputs, test AI agents, catch hallucinations, and ensure your model behaves safely and correctly.
Boutique human evaluators — not giant BPOs. Quality over volume.
Why humanlayer?
WHAT WE DO
AI cannot evaluate itself, and founders need trusted human judgment to ensure their models behave correctly. That’s where we come in. HumanLayer AI provides a boutique, high-quality evaluation layer built for teams that demand accuracy and clarity. We offer fast turnaround, hands-on communication, and expert oversight without the bloated, impersonal BPO structures. Just precise, reliable human intelligence supporting your AI.
LLM Answer Evaluation
We evaluate every output across the dimensions that matter most: correctness, hallucination detection, tone, logical consistency, safety compliance, and overall completeness. This ensures your model isn’t just generating responses but reliable, accurate, and context-appropriate results that your users can trust.
Agent QA
We thoroughly evaluate your AI agents across all critical aspects of performance, including task execution, workflow steps, error detection, user intent understanding, operational efficiency, and overall success rate. This gives you a clear picture of how reliably your agents function in real-world scenarios and where they can be improved.
Safety & Compliance
We assess your model’s behavior through rigorous safety evaluation, including toxicity screening, bias detection, jailbreak attempt testing, and comprehensive guardrail validation. This ensures your AI remains aligned, secure, and compliant no matter how users interact with it.
Domain Specific Review
We bring domain-specific human judgment to areas where nuance truly matters, including fitness, real estate, lifestyle content, European cultural context, and creator-focused tools. This ensures your AI delivers responses that feel accurate, natural, and deeply aligned with the expectations of real-world users in these verticals.
