Prolific vs. Cint

Prolific gives you direct access to 300k+ vetted participants. No sales call required.

To access Cint's Exchange, you need to go through Cint's onboarding and credit process and sign a Buyer contract. Pricing (rate card or dynamic) is set by an account team, with no published rate.

Prolific's managed research services team brings together over 30 years of combined experience in academic research, acting as an extension of your team for all your complex projects. 

Cint offers a managed services option for handling complex projects, though its core model remains programmatic and self-serve by default.

With Prolific, there’s no minimum spend. Pay per participant, starting from your first study. 

Cint doesn't publish a self-serve spend threshold — but access itself requires completing the buyer contract and credit process first, regardless of budget size.

Prolific has an MCP server that lets your agent launch studies, wait on completion, and receive structured responses — without writing API code. 

Cint is working with Potloc to develop and test a Cint Model Context Protocol (MCP).

Prolific recruits, verifies, and monitors its own respondents, tracking behaviour over time to maintain quality. 

Cint pools respondents across multiple third-party panels, so you're sourcing indirectly rather than from a single controlled panel. That means each underlying panel has its own quality control standards, and those inconsistencies can carry through to your results.
 

Our Expert Network spans 90,000+ professionals across 40 countries, covering business, finance, marketing, engineering, healthcare and more. Where most panels verify once, we verify continuously. Every professional is cross-checked against independent signals, including current role, employment history and LinkedIn presence. Job roles are standardised to O*NET titles, so you can get the expert insight you need fast, without guessing whether someone really is who they say they are. Combine with 300+ consumer filters to further refine your audience. Access Experts in seconds from Prolific’s UI or API.

Cint isn't a proprietary panel, so it can't apply one uniform verification standard across all its participants.

Every Prolific participant undergoes identity and quality verification with over 110 checks, plus ongoing behavioural and identity monitoring across studies. 

For Cint verification happens mainly at the panel-partner level before entering the Exchange. Cint's own layer adds tools like Trust Score and third-party fraud checks, but standards vary by supply source.

Prolific enforces a minimum hourly reward of £6/$8 to ensure all participants are paid fairly. 

Cint doesn't publish a company-wide minimum participant pay floor — incentive rates are set per project by individual panel partners and clients.

On Prolific, studies with broad eligibility criteria typically fill rapidly, with a median fill time of 2 to 2.5 hours for a sample size of around 100 participants. 

Cint states the first 100 completes typically arrive within a day.

The 100% Human Guarantee supports high-quality research on Prolific. If a submission in your study is identified as non-human through our Bot authenticity checks, you’ll receive double the costs for that submission as Prolific credits. Since February we’ve checked over 5 million responses have been Just 0.05% were flagged as low authenticity. 

Cint have no guarantee in place.

Prolific goes beyond removing bad actors, investing in educating its participant base about the requirements for AI-moderated studies. This includes a specialised, video-enabled participant pool trained to provide the descriptive, multi-modal feedback that turns a simple interview into a rich data source, backed by interview-experience screening and enforced camera/audio quality standards. 

Cint has general quality layers in place but no built-in filters to screen for participants with prior interviewing experience and no support function to educate or upskill participants specifically for AI-moderated formats.
