Prolific
Recruit verified participants and collect human data for research, AI training, evaluation, and targeted studies.
About Prolific
Prolific helps research and AI teams recruit verified people for studies, model evaluation, and human data collection. Its self-serve platform provides access to more than 300,000 active participants, over 300 audience filters, representative and quota samples, custom screening, direct messaging, workspaces, and unlimited users. Teams can pay as they go without a monthly platform fee. For projects that need more operational support, managed services are available at a custom price and can cover sourcing, participant onboarding, curation, quality assurance, analysis, and reporting. The open API supports study creation, submission approval or rejection, bonuses, messaging, participant groups, short surveys, and workspace administration. Prolific is a practical fit when a team needs targeted human feedback quickly and wants control over recruitment and submission decisions. Because spend depends on each study and managed work requires a quote, buyers should estimate the complete collection budget before launch.
