## 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

## Step1

Step1 is a Chrome extension that describes itself as an AI-based Web3 user graph. Rather than judging accounts on raw activity alone, it analyses behaviour and reputation signals to build a profile of each participant, then estimates how much that user deserves from reward and incentive programs.

The problem it targets is a familiar one in Web3: distinguishing genuine contributors from freeloaders and automated farming accounts. Incentive campaigns are frequently drained by bots and low-effort wallets, while real users are under-rewarded. Step1's stated goal is to shift that balance by scoring quality of engagement and proposing economic models that reward it.

It is a lightweight extension installed from the Chrome Web Store, offered by Step1 official. It collects web history to perform its analysis and declares that this data is not sold to third parties or used for creditworthiness decisions. Note that the listing has not been updated since mid-2023 and has a small user base, so it is best treated as an early-stage Web3 experiment rather than a mainstream productivity tool.

**Pricing & Plans:** Free to install from the Chrome Web Store. No paid tier is listed.

- **AI-driven user graph:** AI and big-data methods combine on-chain signals into a picture of who a Web3 user is and how they behave.
- **Reward optimisation:** Scores and compares participants so that genuine contributors stand out from freeloaders and farm accounts.
- **Fair incentive models:** Aimed at making incentive programs fairer by rewarding high-quality participation rather than volume.
- **Simple Chrome extension:** Installs from the Chrome Web Store and runs alongside your normal Web3 browsing.
- **Cross-platform analysis:** Analyses user activity and reputation across Web3 rather than relying on a single protocol's data.

**Strengths:** Free Chrome extension with no paid tier; Targets a real Web3 problem: separating real users from freeloaders; Runs in the browser with minimal setup; Declares data is not sold to third parties

**Limitations:** Very small install base (roughly 73 users), so there is little community or documentation support; Extension has not been updated since July 2023, which is a long gap for a Web3 product; Requires a Chrome-based browser and an active Web3 wallet to be useful; Claims and metrics around reward optimization are hard to verify independently
