Recruit verifiably human participants.
No artificial ingredients.

The academic-first participant pool. Verified identities, live face-authentication before every study, and a Participant Authenticity Score on every session.

The full Participant Authenticity Score launches in August 2026; identity verification and per-study face-authentication have been live since 2018.

Our Minds contribute to cutting-edge research at leading institutions.

Verifiably human, session by session

Bots, LLM-written answers and click-farms quietly corrupt online data. We fuse dozens of real-time signals into one score per session — the Participant Authenticity Score (PAS) — so you decide with evidence, not hope.

Identity

Verified, then re-verified

Government photo ID, face-matched to a live selfie — and a live face-authentication before every study confirms the same human is present.

Entry gate

Blocked before your stimuli

A sub-30-second pre-study scan hard-blocks known automation and pool-banned fingerprints before the participant reaches your study.

Network & device

Screened at the edge

Datacenter and VPN origins, TLS fingerprints, and headless or automation markers — tiered into hard-stop versus suspicious.

Behaviour

Typed, not injected

Typing rhythm, pointer motion, paste and focus provenance: text that appears without genuine keystrokes is treated as injected, not typed.

Responses

Answer forensics

Timing versus reading time, cross-participant similarity, free-text canaries — and optional session audio, the hardest signal to fake.

No single check decides. Everything converges on one server-side score with three action bands — include, review, exclude — and you set the strictness. We don’t quote a “100% detection” figure; nobody honestly can.

We focus 99% on academic research

Prolific was founded as Prolific Academic — today its growth engine is AI-lab data work, and academia is the discounted tier. On Testable Minds, your study is the main event: human-reviewed before launch, matched to a curated pool, disputes handled by us.

Built and run by academics Earnings capped at $600/year Commission from 10–30%, priced for research budgets

Participant earnings are capped so you sample more naive participants, not professional survey-takers.

Tailored to the needs of academic research

Verifiably human — reconfirmed before every study

Verifiably human — reconfirmed before every study

Our Verified Minds go through advanced identity verification by human and machine. Before each experiment their identity is reconfirmed, so we can guarantee basic demographic details such as age, sex, and nationality.

Attentive participants

Attentive participants

Our participants join because they want to help advance the field of science through their participation. Through earning limits and fair rates we ensure that participants and researchers’ motivations are aligned.

Dispute handling by us

Dispute handling by us

Unlike other platforms, we handle all participant disputes. You only need to communicate with us, although you have the option to directly message your participants through our platform.

Run any online study

Run any online study

Recruit participants for any browser-based survey or experiment. There are additional synergies with studies built in Testable that make collecting data for your research easier than ever.

Target demographics

Target demographics

Use our built-in filtering tool to only target your ideal participants for your studies. If the characteristic you are looking for is not covered, don’t worry: You can build your own short screener surveys to select for any trait.

Choose your data

Choose your data

You only need to pay for data that you approve. Most of our researchers do not reject any participants, but if you find the occasional bad apple, you can reject their result and help us maintain the high quality of our pool.

Scheduled studies

Scheduled studies

Take control of your study timing with advanced scheduling. Choose when your experiment goes into field and during what times of day it should run. You can also account for the local time zone of your participants.

Private panel management

Private panel management

Create your own panels of participants based on previous studies. Use this for longitudinal studies or to easily draw on a subsection of participants with specific characteristics that you curated.
