## 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

## Scite

Scite is an AI-powered research platform built on an unusually deep index of scholarly content. Rather than summarising abstracts, it reads across more than 300 million full-text articles along with preprints, books, patents, clinical trials, grants and datasets. Its distinguishing feature is the Smart Citation: when an article cites another, Scite classifies the context, showing whether the later work supported, contrasted with or merely mentioned the earlier finding. That gives researchers a fast way to judge how well a result has held up.

The platform pairs that citation intelligence with an AI Assistant that answers research questions using retrieved literature, linking each claim back to the specific sentence in the specific paper so answers can be verified in one click. Search runs over full text, helping you find what is actually inside a paper rather than relying on metadata. Collections let you organize and monitor papers, and citation data extends to authors, journals, institutions and funders.

Scite integrates into existing research workflows through an MCP server that plugs into ChatGPT, Claude and other MCP-compatible assistants, a Zotero plugin, a browser extension that surfaces citation badges on the web, and an API for programmatic access. The company is now part of Research Solutions, with publisher agreements covering dozens of publishers plus the open access corpus. Researchers can start with a free trial, and institutional or enterprise access is arranged through sales.

**Pricing & Plans:** Free trial available, with paid individual subscriptions and institutional or enterprise plans priced on request. Students and researchers should check whether their university library already provides access.

- **AI Research Assistant:** Ask a research question and get an answer assembled from the scientific literature, with every claim linked to its originating paper and sentence.
- **Full-Text Search Across 300M+ Articles:** Search more than 300 million articles, preprints, books, patents and datasets using full text rather than abstracts alone.
- **Smart Citation Classifications:** See at a glance whether later work supported, contrasted with, or mentioned a paper, claim, author, journal or institution.
- **Works Where You Write:** Run Scite inside ChatGPT, Claude and other MCP-compatible assistants, or tap citation data through the Zotero plugin and browser extension.
- **Collections, API and Library Integration:** Organize, save and monitor papers in collections, and use the API and full-text holdings options for team or library workflows.

**Strengths:** Citation-context classification that goes beyond simple citation counts; Full-text coverage of 300M+ scholarly works, including patents and datasets; Answers trace back to specific sentences for easy verification; Integrates with ChatGPT, Claude, Zotero and browser workflows

**Limitations:** Full-text depth and premium features sit behind paid plans; Coverage is deepest where publisher agreements exist; niche or regional journals may be thinner; Some institutional access requires checking whether your library already subscribes; Advanced features such as the API and MCP integrations are aimed at heavier users
