Your questions, answered
How does Prolific's infrastructure integrate with our existing tools?
Our API-first approach allows seamless integration with your development environment and evaluation systems. As a result, we support all types of data formats for training and evaluating AI models and products.
Can I run multiple research workstreams?
With Prolific's platform, you can run parallel evaluation programs across different teams and workstreams. Each project can have custom participant requirements, data needs, and timelines while sharing the same infrastructure. This removes bottlenecks and enables independent team operations without duplicating operational overhead.
Can Prolific support large scale annotation and evaluation needs?
Our infrastructure scales from simple pilot evaluations to enterprise-wide data collection programs. With access to 200k+ participants, our flexible API, and expert-led managed services, you can keep expanding the volume and complexity of your evaluations without having to rebuild your operational foundation.
How does Prolific compare to traditional labeling providers?
Traditional labeling providers use large annotation teams on hire. They offer little transparency into their profiles and selection criteria.
Prolific gives you direct access to verified evaluators through self-serve or managed options. This gives you both the quality assurance of managed services and the transparency and control of direct access, with much faster turnaround times.
