## 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

## Querri

Querri positions itself as the "AI data analyst for everyone." Rather than starting from a chart builder or a SQL editor, it starts from a question. Users connect apps and warehouses, Querri cleans and unifies the data into a Library that captures how the business actually works, and then answers are grounded in that shared context so finance, marketing, ops, and leadership all quote the same numbers.

The platform sells itself on reducing the setup tax of analytics. A connector agent handles integrations with systems such as Salesforce, HubSpot, NetSuite, QuickBooks, and Snowflake, and the onboarding promise is days rather than quarters. Beyond ad-hoc chat, Querri can rebuild an existing dashboard from a screenshot, schedule nightly monitors and insights, and package analytical workflows into reusable "Skills." An MCP integration lets teams pull Querri's cleaned data into Claude, ChatGPT, or Gemini, and there is a CLI for terminal-driven queries.

Querri also targets builders and resellers: consultants and vertical SaaS vendors can white-label the platform and embed it into their own products through an API, SDK, and CLI. The company advertises SOC 2, ISO 27001, and HIPAA alignment, plus workspace-level access controls for teams. Pricing is not published in detail on the homepage; there is a free start and a trial-style entry, then paid plans, so buyers should confirm current tiers on the pricing page.

**Pricing & Plans:** Free start available with paid plans; exact tier prices are not published on the homepage, so confirm on the Querri pricing page.

- **Library and governed data model:** Connect sources, then clean, profile, and model them into one Library that records business context, definitions, views, and facts so every answer uses consistent numbers.
- **Natural-language chat with export:** Ask in plain English and receive answers, charts, dashboards, slide decks, or Excel workbooks from the same conversation, with no SQL required.
- **Screenshot to dashboard:** Turn a picture of an existing dashboard or report into a working, data-backed dashboard inside Querri.
- **Nightly monitors, Skills, and MCP:** Schedule recurring insights, codify repeatable analytical workflows as Skills, and bring cleaned data into Claude, ChatGPT, or Gemini via MCP and a CLI.
- **White label and embed:** Agencies and SaaS vendors can rebrand and embed Querri in their own products using the API, SDK, and CLI.

**Strengths:** Question-first design keeps the workflow accessible to non-technical business users; Single governed Library reduces conflicting numbers across teams; Broad connector lineup plus MCP support for external AI assistants; Reusable Skills, nightly monitors, and screenshot-to-dashboard speed up recurring reporting

**Limitations:** Full pricing details are not on the homepage, so cost needs a sales or pricing-page check; Best results depend on clean source systems and a real data-modeling effort; Deeper white-label and embedding work may require engineering resources
