Prolific is a platform where researchers can recruit participants for their online studies. Prolific integrates with survey tools like SurveyMonkey or Qualtrics and experiment platforms such as Gorilla. It's easy to sign up, connect your survey or experiment and begin recruitment. Participants can be pre-screened using dozens of demographic-filters, and study responses start arriving in minutes. The platform launched in 2014 with a focus on high data quality and ethical participant reimbursement, and has built up a large community of researchers and participants, with over 36,000 studies completed so far.
