Our platform is designed for immediate deployment. Self-serve projects can launch in minutes, and results can start to arrive within hours. Managed services projects will depend on various factors relating to project scope, evaluation requirements, and other considerations.
You can connect Prolific to any data collection interface using our UI or API. Collect any data format—text, images, audio, and video—for a wide range of alignment techniques, such as supervised fine-tuning (SFT), Reinforced learning from human feedback (RLHF), direct preference optimization (DPO), and more.
With our self-serve platform, you control the process. We provide the infrastructure and participants. You design tasks in your evaluation tool or our AI Task Builder, set criteria, and analyze results.
With managed services, we handle everything from participant sourcing to quality assurance. You define requirements and get verified results.
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
