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-powered, Amazon TOS-compliant negative review removal service
Custom scanning software analyzes review patterns and content to isolate negative reviews that actually violate Amazon's policy categories.
A proprietary methodology drafts appeals that identify the exact violation and back every claim with structured, verifiable evidence.
A trained human team submits each case with accurate categorization and formatting through Amazon's official appeal process, never grey-hat tactics.
Submit an ASIN to receive a full violation scan, estimated removable review count and projected star-rating and revenue impact within 24 hours.
