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.
Turn spreadsheet data into custom choropleth maps and interactive embeds
Choose from world, continent, country, US state, county and ZIP code maps, each divided into regions you can color individually.
Paste from Excel, upload CSV, connect Google Sheets or Notion, or type a prompt like "color states by population" and let the AI map it.
Smart color scaling picks palettes and breakpoints for your dataset and generates a matching legend without manual configuration.
Publish a live map with tooltips, popups, click-through links, pan and zoom, then embed it via one line of code or by pasting the link into Notion, WordPress, Ghost or Substack.
