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 answers grounded in 300M+ scholarly full texts
Ask a research question and get an answer assembled from the scientific literature, with every claim linked to its originating paper and sentence.
Search more than 300 million articles, preprints, books, patents and datasets using full text rather than abstracts alone.
See at a glance whether later work supported, contrasted with, or mentioned a paper, claim, author, journal or institution.
Run Scite inside ChatGPT, Claude and other MCP-compatible assistants, or tap citation data through the Zotero plugin and browser extension.
