High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.

Reads questions from typed text or live system audio, so answers appear as soon as the interviewer finishes asking.
Show, hide, move, and send responses entirely through keyboard shortcuts, with no mouse movement that could give it away.
Set your programming language, spoken language, role, and custom prompts so answers match the interview you are walking into.
