Flexible, usage-based pricing

Prolific helps you collect high-quality human data to power AI development and research. Whether you're developing AI models and products, gathering behavioral insights, or conducting market research, we connect you with verified participants who match your exact needs.

We help you collect quality data and human feedback faster and more reliably than alternatives. Our platform combines instant access to verified participants, transparent pricing, and flexible expertise to match your needs. Whether you're collecting data for AI development or research, you can start receiving responses within hours while maintaining end-to-end transparency into your data collection.

We manage quality by maintaining a bar for entry and participation on our platform. We have 200,000+ active participants on the platform, with more than a million on the waitlist. Protocol, our AI-powered quality monitoring system, runs 40+ checks to verify identity during onboarding and analyze behavioral data when they contribute data to ensure only verified participants on the platform. You have full control over submission approval and can reject submissions that show negligent behavior (e.g. failed attention and comprehension checks). For more details on approvals and rejections, check out our help center article.

We offer three flexible plans to match your needs:

• Self-serve: Get immediate access to our full platform and general crowd. Perfect for teams who want to launch projects quickly and manage their own data collection process. Includes all core features like demographic filtering, custom screening, and integrations.
• Self-serve Plus: All the benefits of self-serve, plus expert support for your custom needs. Ideal when you need specialized participants or help managing complex, ongoing projects. Includes dedicated participant pool management, custom sourcing, and fast-track support.
• Managed Services: End-to-end project support from our expert team. Best for organizations who want to focus on results while we handle everything from strategy to delivery. Includes full project management, quality assurance, and comprehensive reporting.

You can switch between plans as your needs evolve.

Our pricing is straightforward and transparent:

• Self-serve: You pay a participant reward that you set, plus a platform fee.
• Self-serve Plus and Managed services: Pricing is customized based on your project scope and requirements.

For self-serve users, our platform fee is usually 42.8% for corporate customers, and a discounted 33.3% for academic or non-profit customers.

Typically, we recommend you pay participants at least £9.00 / $12.00 per hour, while the minimum pay allowed is £6.00 / $8.00 per hour. For tasks requiring specialized skills (like experience in AI annotation tasks, coding experience, or advanced STEM degrees), we recommend higher compensation, to reflect their expertise and the complexity of the tasks. Fair compensation leads to better data quality and higher engagement, especially when publishing complex tasks or studies.

You don’t need to sign a contract or pay for a subscription to get started. You can simply pay as you go by adding funds to your wallet and launching a study or a task.

Our participant management service includes a dedicated support to coordinate all participant needs. This usually includes delivering any custom training modules, curating the right pool of participants, monitoring engagement, quality assurance, and strategic planning to build participant pools for ongoing needs.
