Prolific

Prolific is an online platform designed to help researchers, product teams, and organizations recruit high-quality human participants for studies, surveys, and experiments. It provides access to a large, diverse pool of verified participants who can be targeted based on detailed demographic and behavioral filters, enabling precise sampling for academic research, UX testing, market research, and data collection. The platform supports a wide range of study types, including behavioral experiments, longitudinal studies, randomized controlled trials, and remote usability tests, and integrates easily with external survey tools and experiment platforms.

Prolific offers transparent participant compensation, pre-screening tools, and built-in quality controls such as attention checks and performance metrics to reduce low-quality responses and fraudulent activity. Researchers can manage the full lifecycle of a study, from designing eligibility criteria and setting quotas to monitoring live participation and exporting clean, structured datasets.
