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.

Search a database of tens of millions of videos to find outliers — videos beating their own channel baseline by 5x–10x — along with the packaging that got them there.
Hand the agent an idea and it researches, outlines, writes multiple hook options, optimizes for retention, then humanizes the tone to match your voice.
Start from 157 proven thumbnail formats or clone a competitor's winning style, and get a publish-ready thumbnail in about a minute.
Turn a finished script into a complete video with voices, B-roll, motion graphics, and captions across 14 signature visual styles, or go faceless with an AI avatar.
