Pay, from live listings
Pay transparency: 2910 of 3060 current listings (95%) state what they pay. 2659 of the rate-carrying listings hedge the figure ("approximately", "up to"), so it is an indication rather than a commitment.
Computed from 58 distinct advertised rates across 2844 of 3060 currently listed roles that disclose an hourly rate - Prolific Participants repeats the same pay wording across listings, so each distinct rate counts once. Updated daily. See the AI-training pay index for how Prolific Participants compares.

Notes
Not every study is AI-related; include task category filtering in aggregator. Roles are scraped from Prolific's Greenhouse hiring board (job-boards.eu.greenhouse.io/prolificacademicltd) - one real requisition fans out across many city/language variants (117 requisitions -> ~2,700 postings after excluding plain Survey/Study Participants postings, which describe this same participant-marketplace business rather than a distinct role). Descriptions carry leftover ChatGPT chat-UI markup and repeated boilerplate; scripts/scrape-prolific.mjs sanitizes both before storing. User manually spot-checked listings on 2026-07-25 and confirmed they look legitimate. Prolific runs both a participant marketplace (open registration, research studies) and an expert network (AI training/evaluation roles) - the scraped role listings come from the expert-network side, and comparison copy must not describe it as marketplace-only.
