Analyse YouTube comments for sentiment, emotion and topics — and query them directly.
See how actively viewers responded to a video, with engagement metrics derived from the comment section rather than from view counts alone.
Understand the emotional temperature of a comment section through automated sentiment and emotion classification of individual comments.
Identify the most frequently discussed subjects so you can see what viewers actually took away from the video.
Type a question and get an answer grounded in the actual comments, useful for gauging demand for a follow-up video.
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.
