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 marketing, ads and follow-up autopilot for real estate agents
A week of real estate content is written, scheduled and posted to TikTok, Instagram, Facebook, LinkedIn and X every week, aimed at saving agents hours of manual work.
Campaigns for new-to-market listings, open houses, price drops and sales are generated automatically and billed per ad, so agents only pay for the ones they run.
Captures and tracks leads, flags the most valuable ones using AI, transcribes calls, and sends automatic text and email follow-up with ChatGPT4.
Agents claim a ZIP code on the national PropertySimple property portal so local buyers see their photo and contact details, with generated traffic pointed at the area.
