Get high-quality text, voice, image, video, or interaction-driven feedback from our diverse, vetted, and reliable participants.
From rich, focused datasets, to API-driven data annotations at scale, gather high-quality feedback, iterate fast – and launch first.
Generate rich, human-powered multimodal data for AI
Build more accurate models. And iterate faster.
Our pool contains 150k+ fully vetted and verified participants, who are monitored constantly by our automated Protocol algorithm. It’s balanced, bot-free, and demographically diverse.
Diverse, vetted, and bot-free pools
Our taskers are engaged and reliable and deliver rich, accurate annotations and data.
Reliable taskers with rich answers
We have taskers from 38+ countries who speak 80+ languages.
Representative samples are also available for the US and UK.

Filter taskers fast
Integrate any third-party tool or custom-built tool with a simple link.
Or integrate, scale, and automate with our API.
Or integrate, scale, and automate with our API.
Tools
Use your own tools
Save specific sets of tasker filters that reflect the needs of your organisation or project. Then easily apply them again and again to new studies.
Filter-sets
Set rules and save filter-sets
Once you’ve used a tasker you can re-contact them, save them, or train them for specific tasks.
Communication
Contact, train, and retarget taskers
Put your high-performing or especially trained participants into groups and re-target these across different tasks or studies.
Participant groups
Group high-performing taskers
If you can control the uniqueness of your tasks, then set up multi-submissions to allow a participant to take your study over and over. (Thresholds configurable).
Multi-submissions

Data for AI that sets the standard
Planned EU legislation means AI companies will need to prove where their data has come from. All data sourced via Prolific is fully auditable, as well as being bot-free and mitigating bias.
Collect complete datasets in less than 2 hours
Getting started is simple. With no contract or subscription – just a pay-as-you-go fee for each completed response.
