Ethical data that benefits everyone
We invest in and protect our participants. So you can build your research on rich data and ethical practices.
Fair pay is crucial to high quality responses. Our minimum pay threshold ensures you get the detailed data you need and participants get the compensation they deserve.
We protect the identities of our participants. You get their honest responses because they feel secure in giving them.
Participants always opt in to tasks. They don’t have to take part in anything they don’t want to do.
Frequently asked questions
Prolific is a platform that connects researchers and companies with high-quality participants you can trust. You can also use the platform to manage your relationship with participants. This includes making payments and recruiting the same participants again.
No corner cutting - We invest in our participants. Paying participants fairly and treating them well is crucial to getting their best responses. Our customers love the rich, accurate, and comprehensive free-text responses they get from our participants. And that’s before you even have to train them on any task. Our robust vetting processes, which includes ID and discrepancy checks, also ensure participants are real and answering honestly.
Designed for speed and scale - Run projects with thousands of participants. Automate your flows with our API. Re-target the best participants again and again with no time delays.
English fluency - While we have participants in all OECD countries, they’re mostly based in the US or UK and speak native English. And we have over 130,000 active and ready.
Prolific is incredibly flexible. You can use it for many different use cases — too many to list! If we have the participants you need and you have the annotation tool then we’ll work well together. If you can’t see the participant demographics you need in our pool, chat to us. We’ll respond quickly and can often help.
Integrate any annotation tool, whether that’s your own tool or a third party tool. As long as you don’t need participants to share personally identifiable information, then you’re good to go.
Try adding as many relevant filters as you can. Then run a short survey where you ask further screening questions. You can often find the audience you need - but we might not have asked the unique questions you’re looking for.
You can set up tasks to start however you like, as long as you pay participants for their time. For example, you could include written instructions or an explainer video and a few sample tasks for them to practice. You can easily split tasks into multiple sessions and only graduate the most accurate participants to the next session.
