03What Tavra does differently
What Tavra does differently
- Identity-verified workers
- Every worker's identity is verified by Stripe before their first paid task.
- Checks agreed up front
- Workers see every check before they accept; a rejection needs a reason tied to one of them, and disputes go to an independent reviewer.
- Paid when posted
- No balance to load. Each batch is paid when posted, and rewards nobody earns are refunded automatically.
- Quality report
- Every batch ends with a report of the checks run, agreement scores and re-runs. Rejected work is re-run at no extra fee.
- Start estimate
- Before you pay, you see when the batch should start; if Tavra promises a start time and misses it, the fee is refunded.
04Before you decide
Before you decide
Prolific is open now. Tavra opens after launch testing and starts with US residents aged 18 and over. If your study needs to run before Tavra opens, or needs participants outside the United States, Prolific may suit you better.
