## Prolific

Prolific operates a marketplace where researchers and organisations post studies and verified participants complete them for payment. The pitch is quality over volume: instead of a massive but unvetted panel, Prolific verifies participants, applies attention and honesty checks, and lets requesters filter by detailed demographic, professional, and behavioural criteria. That makes it possible to target narrow, representative groups — for example coding experts, healthcare professionals, or specific national populations — which matters when a study compares groups or needs to generalise beyond a convenience sample.

In recent years Prolific has leaned heavily into AI. Its AI offering covers human preference data for fine-tuning and reinforcement learning, safety evaluation, red-teaming, and benchmarks across languages and tasks. It also publishes a leaderboard of model quality based on human evaluation, and offers developer-facing tooling such as a human-feedback API, agent workflows, and a Model Context Protocol server so AI pipelines can call for human input programmatically. Alongside this, the original academic and market-research business remains central.

Pricing is usage-based. Requesters pay for participant rewards plus a platform fee, and researchers either fund studies per response or talk to sales for larger programmes and managed services. Because rates depend on study length, targeting criteria, and volumes, published list prices are rare — the platform directs larger customers to a sales conversation.

**Pricing & Plans:** Usage-based for requesters: you pay participant rewards plus a platform fee, with custom quotes for large or managed programmes. Participants earn per completed study; joining is free.

- **Verified, targetable participant pool:** Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
- **AI data and human feedback:** Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
- **Built-in data-quality controls:** Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
- **Fast study launches:** Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
- **Participant side with guaranteed pay:** Participants get a clear per-study reward, flexible scheduling, and a minimum pay standard enforced by the platform.

**Strengths:** Strong focus on data quality with verification and attention checks; Granular targeting that supports niche and representative samples; Fast turnaround compared with traditional panel providers; Growing AI-focused tooling including a human-feedback API and MCP server

**Limitations:** Pricing is quote-based for many use cases, which makes budgeting less transparent up front; Participant availability in some narrow demographics can be limited or slower to fill; Costs add up quickly for large multi-country or longitudinal studies

## Screenify

Screenify positions itself as a fully automated screener rather than another skills-assessment tool. The company reports that customers see around a 33% reduction in time to hire, 10x more hiring capacity, and up to 90% lower hiring costs, figures it attributes to removing scheduling back-and-forth and manual first-round screening. Customer testimonials cited on the site mention over 80% alignment between Screenify's evaluations and internal team assessments, which is the kind of claim worth validating against your own roles during a trial.

The workflow is deliberately simple. A recruiter builds the interview, writes the questions and scoring criteria, and sends invitations to applicants. Candidates receive an email with a custom intro video and then complete the conversation on Google Meet or Zoom at any hour, which removes the usual scheduling friction and tends to improve completion rates. Screenify then returns scored summaries so the hiring team can shortlist quickly.

Integration is handled through applicant tracking systems as well as non-ATS tools such as Typeform and Airtable, and companies without an ATS can still share candidate details inside the platform. Plans scale by job role and interview volume, with a 7-day free trial on paid tiers and custom pricing for high-volume or private-infrastructure requirements.

**Pricing & Plans:** Screenify uses volume-based pricing with a 7-day free trial on paid plans: Starter at $149/month covers 1 job role and up to 100 interviews per month, Growth at $629/month covers up to 5 job roles, 500 interviews, up to 3 integrations, and custom branding, and larger requirements are quoted custom. Credits are only charged for interviews that candidates start and join.

- **Fully automated screening:** Create an interview, define scoring criteria, and send invitations automatically so screening, scheduling, and feedback collection happen without manual coordination.
- **Adaptive, personalised interviews:** Every interview is tailored to the role and the candidate's experience, and the AI follows up on responses the way a human interviewer would.
- **Consistent AI scoring:** Candidates are scored against your company's criteria using AI evaluation, which reduces interviewer bias and keeps comparisons fair across applicants.
- **Candidate-friendly experience:** Applicants get an email invite, a custom intro video, and the freedom to interview any time through Google Meet or Zoom, with your own branding throughout.
- **ATS and workflow integrations:** Connect Screenify to your ATS or to no-code tools like Typeform and Airtable so candidate data flows into the systems you already use.

**Strengths:** Fully automates first-round screening, scheduling, and feedback collection; Candidates can interview any time via Google Meet or Zoom, improving completion rates; AI scoring applies your criteria consistently and reduces interviewer bias; Works with ATS platforms as well as non-ATS tools like Typeform and Airtable

**Limitations:** Pricing starts at $149/month, which is steep for very small teams or occasional hiring; Interview credits are metered monthly, so high-volume hiring seasons can push you into an upgrade; Advanced features such as custom branding and multiple ATS integrations are gated behind the Growth tier; AI scoring is consistent but still benefits from a human review pass for senior or highly specialized roles
