AI Evaluation

Real Humans for AI Training & Evaluation

Survey Diem connects AI companies with verified US consumers who can evaluate model outputs, compare responses, test AI experiences, and provide high-quality human feedback.

AI needs real human judgment.

Models can generate answers, conversations, recommendations, summaries, and decisions at massive scale. But companies still need people to tell them what is helpful, trustworthy, natural, safe, accurate, and aligned with real user expectations.

Preference Ranking

Have verified users compare AI outputs and identify which response is clearer, more useful, more human, or more trustworthy.

Model Evaluation

Collect structured feedback on AI performance, hallucinations, tone, helpfulness, relevance, and user satisfaction.

Trust & Safety Testing

Use real people to evaluate whether AI systems produce inappropriate, misleading, unsafe, biased, or low-quality responses.

Most survey companies think:
“AI tasks are not surveys.”

But:

  • RLHF,
  • model eval,
  • preference ranking,
  • trust/safety evaluation,
  • human feedback collection

…all evolved from the same fundamental mechanics as survey research.

Built for verified human feedback.

Survey Diem was designed around data quality from the beginning. Our panel runs through a mobile app, uses identity verification, blocks VPN-driven fraud, and keeps panelists inside a controlled app experience instead of exposing raw survey links.

Example AI evaluation tasks

Compare Two AI Responses

Show users two model outputs and ask which is better, safer, clearer, or more persuasive.

Review AI Conversations

Have consumers rate chat quality, empathy, helpfulness, trust, and whether the assistant understood the user.

Test AI Agents

Let real users evaluate whether shopping, research, support, or productivity agents successfully complete tasks.
