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.
AI blueprint analysis and instant material takeoffs for roofing contractors
Ask questions about any roofing project and get answers on pitch, quantities, flashing details and material requirements, each tied back to the exact place in the blueprint or spec.
Revent rates each opportunity against your crew's skills and capacity so you can prioritise the bids you are actually likely to win.
Automatically counts shingles, underlayment, flashing and other components and consolidates roof specs, measurements and quantities in one place.
Scans lengthy specification packages and RFP documents to extract the details that drive an estimate, replacing manual reading and spreadsheet work.
