## What Prolific does

Prolific connects researchers and AI teams with vetted participants. For AI work it offers human evaluation of models and collection of human feedback ([Prolific](https://www.prolific.com/model-evaluation)). It is a natural fit for [RLHF and preference data](https://aidataforsale.com/data/rlhf-preference-data) and [evaluation datasets](https://aidataforsale.com/data/evaluation-datasets) where you need a defined, demographically described group of people.

## Where it fits

Participant platforms create new judgments on demand. They do not supply the real-world archives (support conversations, code history, documents) that AI teams also license. Many teams combine the two: licensed data for training, participant panels for evaluation.

## Things to check before you sign

- How participants are screened and paid, and how quality is checked.
- Whether consent covers the specific AI use you plan.
- What demographic and expertise filters are available.
