## 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

## Propwrite

Propwrite is a web-based tool aimed at the Norwegian real-estate market. It focuses on the paperwork side of property transactions rather than listing marketing: you search an address, get an overview of registered rights and encumbrances, and order authoritative documents such as the grunnbok and pantebok straight from Kartverket, the national mapping and cadastre authority.

The pitch is speed and simplicity. Instead of working through traditional ordering routes that take longer, Propwrite presents a streamlined ordering flow and delivers the documents faster, which matters for agents, lawyers and buyers working against deadlines. Documents come from Kartverket's authoritative registers, so they carry the same legal standing as ordering them yourself.

Access requires logging in; new users can register from the login page. Pricing is not published on the site, so exact per-document costs should be confirmed after signing in. Interface and content are in Norwegian, reflecting its domestic focus.

**Pricing & Plans:** Account registration appears free; document orders are the paid element and no public pricing page exists, so exact per-document costs are not published.

- **Search by address:** Enter a Norwegian property address to retrieve a consolidated view of the property's registered information.
- **Easement and encumbrance lookup:** See tinglyste servitutter, including rights of way, utility-line rights and other registered encumbrances.
- **Direct document ordering:** Order pantebok, grunnbok and other property documents pulled directly from Kartverket's systems.
- **Faster delivery:** A streamlined ordering process intended to get documents to you quicker than traditional methods.
- **Official-source documents:** Documents originate from Kartverket's authoritative registers, the same source used by authorities.

**Strengths:** Searches and document orders live in one Norwegian-focused interface; Documents come from Kartverket's authoritative registers; Easement and encumbrance overview helps surface hidden rights early; Registration is straightforward from the login page

**Limitations:** Processing and delivery times depend on Kartverket's own systems; Content is Norwegian-only, which limits use outside Norway; No public pricing page, so costs must be checked after signing in
