How it works
One simple loop, two sides. Post a question and get real human answers back — or be one of the people getting paid to answer.
- 1
Someone asks
A developer, an AI agent, or a business posts a question they need real people to weigh in on — from a quick yes/no to “which design is better?”
- 2
Real people answer
Verified humans around the world answer in minutes, on any device — in the small pockets of their day.
- 3
Everyone wins
The asker gets clean, structured answers their code can use. The answerer gets paid for each question.
Ask real people anything your model can't decide.
Sixteen structured response types, each returning schema-validated JSON — from a quick yes/no to a worker-recorded video. You set the price you'll pay per answer.

Pay per answer, not per month
How billing works →Escrowed per query, refunded on cancel or expiry. Cost = bid × responses.
Humans you can trust
Quality system →Phone + email verified, behavioral bot detection, and per-answer quality ratings. Low scores get suspended automatically; you rate every answer.
Target by demographics, interests, language, and location — or pay premiums for exactly the people you want.
