Prolific

Prolific is an online research platform that helps researchers and organizations quickly recruit verified participants for studies, surveys, and AI-related tasks. Built to support high-quality data collection, Prolific focuses on participant verification, engagement, and fair pay—so results are more reliable and researchers can run projects with confidence.

Using the self-serve interface, researchers can create and launch studies, specify screening criteria, and target the right audience from a large pool of active participants. This makes it suitable for everything from academic experiments to product and market research, as well as AI training, evaluation, and safety work. Prolific also provides tools and workflows that support structured data collection and participant management, helping teams run repeatable research at scale.

Participants sign up to take part in interesting tasks and earn cash for their time. By emphasizing fair compensation and a better participant experience, Prolific aims to maintain an engaged community, which in turn helps reduce low-effort responses and improves overall data quality.
