## 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

## Realyst

Realyst is a browser extension built for people who evaluate single-family homes and want the numbers without leaving the listing page. Once installed, it adds its own analysis layer on top of Zillow.com, so a normal property page also shows a running model of what that home would look like as a rental: rent assumptions, mortgage terms, vacancy allowance, renovation estimates and the resulting return metrics. The pitch is speed — investors and realtors can screen listings far faster than rebuilding a spreadsheet for every address.

The extension leans on a configurable financial model rather than a single canned output. You adjust inputs such as expected rental rate, mortgage rate, vacancy rate and renovation budget, and the cash-on-cash return and ROI figures update to match your assumptions. A neighbourhood comparison view can line up the profitability of up to 80 nearby properties at once, which makes it easier to spot the outliers in a subdivision before scheduling showings. Results can be saved and exported to CSV or PDF for later review or sharing with a partner or client.

Realyst also layers in AI assistance: five GPT-4 powered prompts cover things like renovation estimates and neighbourhood market trends, and homeowners and buyers get a plain-language PDF summary with nearby comparables plus property, neighbourhood and demographic context. A two-day free trial is offered through in-app purchase, and the extension is distributed on the Chrome Web Store.

**Pricing & Plans:** Free two-day trial via in-app purchase; continued use requires a paid subscription (pricing shown in-app).

- **Adjustable financial model:** Tune rental rate, mortgage rate, vacancy rate and renovation estimates to see how each assumption moves cash-on-cash return and ROI.
- **Neighbourhood-level comparison:** Compare the projected profitability of up to 80 nearby single-family properties in a single click to spot the strongest candidates fast.
- **GPT-4 powered insight prompts:** Five built-in AI prompts generate quick takes on renovation costs, market trends and other decision inputs that are awkward to look up manually.
- **Export and reporting:** Save results and export to CSV or PDF, and generate a homeowner/buyer summary that includes comps, neighbourhood and demographic context.
- **Zillow-native workflow:** Everything runs on the listing page you are already viewing, so there is no separate app to open or address to re-enter.

**Strengths:** Analysis appears directly on Zillow, so screening requires almost no extra steps; Inputs such as rent, vacancy and mortgage rate are editable instead of fixed; Neighbourhood comparison over many properties speeds up shortlisting; Exports to CSV and PDF make results easy to share or archive

**Limitations:** Only works on Zillow listings for single-family homes; Insight quality on any given address depends on Zillow's underlying data; Free trial is short and pricing must be checked inside the extension
