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.
Source-backed AI research over SEC filings for public companies
Ask plain-English questions about 10-Ks, 10-Qs and 8-Ks. The assistant retrieves the relevant filing excerpts and streams an answer with citations you can open to inspect the source text.
Deep Mode extracts entities and relationships from filings and maps companies, people, products, ownership, strategy and risk into a dual-view network where every node links back to evidence.
Search extracted connections to answer who is tied to whom and how, then follow dated events across filing periods to see how leadership, strategy and risks evolved.
Add companies to a watchlist and get AI-summarized notifications when a new 8-K, 10-Q or Form 4 lands, with insider transactions organized for quick review.
