## 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

## You.com

You.com began as an AI-native search engine built around user control and privacy, and has since grown into a search-and-inference infrastructure company. Today its centre of gravity is the developer platform: a real-time web index exposed through Web Search, Contents, Answer, Research and Finance Research APIs, tuned for feeding live, citable data into large language models rather than for human browsing alone. Web Search returns ranked results in roughly 0.4 seconds at p50, Contents turns URLs into clean Markdown or HTML, and the research tiers plan, search repeatedly and cross-reference sources before answering.

The Inference Router is the other pillar. It provides one OpenAI-compatible chat completions endpoint that routes across leading open-weight and third-party models, with multi-provider failover, per-model cost visibility, usage and spend controls, and optional built-in You.com web search so requests can be grounded in fresh results without a separate integration. Security features include US-hosted models, zero data retention options and a 99.9% uptime SLA for the enterprise tier.

A consumer-facing AI search and assistant experience remains available, including an interactive demo of the search API on the homepage. The product is primarily aimed at engineering teams building RAG pipelines, agents and chat products who would otherwise assemble search, scraping and model routing themselves.

**Pricing & Plans:** API pricing is per call with no minimums, seats or platform fees. A free tier offers 100 Web Search queries per day via the MCP server with no API key or card. Paid usage includes Web Search at $5 per 1,000 calls, Contents at $1 per 1,000 pages, Answer at $5 per 1,000 calls, Research from $12 to $1,200 per 1,000 calls depending on depth, Finance Research from $110 per 1,000 calls, and model-dependent Inference Router pricing. Enterprise plans add custom QPS, SLAs and dedicated support.

- **Real-time Web Search API:** Ranked web and news results returned in around 0.4 seconds at p50, with highlights, knowledge, extraction and domain filters for production RAG workloads.
- **Contents API:** Submit URLs you already have and get back clean Markdown or HTML per page, priced per page returned rather than per request.
- **Agentic research endpoints:** Answer returns a cited response in one call, while Research plans, reads full pages and cross-references sources across five depth tiers.
- **Inference Router:** One OpenAI-compatible chat completions API that runs leading open-weight models with automatic multi-provider failover.
- **Built-in grounding and security:** Optional server-side You.com search grounds model responses, with US-hosted models, zero data retention, SOC 2 and DPA-ready terms.

**Strengths:** Fast, cited real-time web data designed for LLM consumption; Generous free MCP tier of 100 searches a day with no API key; Transparent per-call pricing with no seats, minimums or platform fees; Inference Router combines many models with built-in web grounding

**Limitations:** The platform is developer-first, so non-technical users get less from it; Every endpoint is billed per call, and deep research tiers add up quickly; The consumer search and assistant product is no longer the main focus
