## 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

## PseudoEditor

Writing pseudocode usually means wrestling with a plain text editor: no highlighting, no error checking, no way to save your work across devices. PseudoEditor was created to fill that gap — the team describes it as the first browser-based dedicated pseudocode editor and compiler, and the core editor remains free to use.

The editor gives you dynamic syntax highlighting for keywords, functions, data types and conditionals, plus autocomplete for common constructs. A built-in compiler lets you test whether what you wrote actually behaves as intended, catching structural mistakes while you design the algorithm rather than after you have already translated it into code. Light and dark themes keep long sessions comfortable.

Paid features extend the editor into a learning and translation tool. PseudoEditor Pro unlocks an AI Tutor, intelligent code generation, and unlimited use of converters that translate pseudocode into Python, C++, and other languages, plus an ad-free interface. Schools and universities can also purchase institutional licensing with teacher controls and specification-aligned compilers.

**Pricing & Plans:** The editor and compiler are free to use and supported by ads. PseudoEditor Pro is a paid upgrade that adds the AI Tutor, code generators, unlimited converter use and ad removal; bulk institutional licensing is available for schools and universities.

- **Pseudocode editor with syntax highlighting:** Keywords, functions, data types and conditionals are highlighted, with autocomplete and light or dark themes to make writing algorithms faster.
- **Built-in pseudocode compiler:** Run your pseudocode in the browser to verify logic and surface structural errors before you translate it into a real language.
- **Cloud project saving:** Create a free account to store projects securely online and pick them up from any device, at home or in class.
- **AI code conversion (Pro):** Convert pseudocode into Python, C++ and other programming languages, with a large free allowance and unlimited use on Pro.
- **Exam board and institutional support:** Toggle syntax rules to match AQA, OCR, CIE, Edexcel and IB specifications, with bulk licensing and teacher controls for classrooms.

**Strengths:** Free core editor and compiler with no install required — it runs in the browser; Purpose-built for pseudocode, unlike general code editors that have no pseudocode mode; Covers major exam board specs (AQA, OCR, CIE, Edexcel, IB) which matters to students; Cloud saving and cross-device access for projects

**Limitations:** Advanced AI features such as the tutor and unlimited converters sit behind the paid Pro tier; The free version is ad-supported, which can distract during longer study sessions
