## 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

## Splodge: Paint, Draw & Art

Splodge splits its interface into two clearly separated worlds. The studio side is built for real artwork: hundreds of brush styles with pressure response, layers and layer groups, masks, adjustment layers, perspective and symmetry guides, Quick Shape for clean geometric lines, re-editable text, and large high-resolution canvases with autosave and crash recovery. A photo effects panel can restyle an imported image with looks such as Cartoon, Oil paint, Neon or Glitch, and the effects stay re-editable so the original photo is never altered. A time-lapse feature replays any painting as a shareable video.

The learning side is deliberately oversized, warm and almost reading-free, aimed at younger artists though enjoyable at any age. Learn to Draw walks users through shapes step by step and awards a star for each attempt. The Coloring Book offers hundreds of outlined pictures to tap-fill, after which a "Grade me!" button evaluates how much was colored and how neatly the user stayed within the lines, responding with sparkles, stars and medals. Every finished piece is saved to a personal My Art shelf.

Child safety is treated as a design constraint rather than an add-on: a parental gate guards every exit, setting and purchase, there are no ads and no outbound links. Splodge is free to start, with an optional subscription unlocking the full studio, plus a one-time lifetime purchase. It is published by Toolbone LLP, a Singapore-based developer.

**Pricing & Plans:** Free to start. An optional subscription unlocks the full studio with monthly, 3-month, 6-month and yearly plans, plus a one-time Lifetime purchase. Billing runs through Google Play and everything sits behind a parental gate.

- **Layered painting studio:** Pressure-sensitive brushes with hundreds of styles, layers and groups, layer masks, adjustment layers, selections, transform tools and re-editable text.
- **AI-graded coloring book:** Tap-fill hundreds of outlined pictures, then press "Grade me!" so the app assesses coverage and line discipline and celebrates with sparkles, stars and medals.
- **Learn to Draw guides:** Friendly step-by-step shape tutorials that award a star for every attempt, building real drawing skill without pressure.
- **Re-editable photo effects:** Apply Cartoon, Oil paint, Neon, Glitch and other looks to an imported photo, and change them later without the original image ever being altered.
- **Parental gate and no ads:** Exits, settings and purchases are locked behind a parental gate, with no advertising and no links leading outside the app.

**Strengths:** Equally strong as a real art studio and as a kids' learning app; AI grading gives encouraging, non-judgemental feedback instead of scores; Strong child-safety design with a parental gate and no ads; One-time Lifetime purchase available alongside subscription plans

**Limitations:** Android only, with no iOS release; Photorealistic, professional-grade painting is not the focus; The full studio requires a subscription or lifetime purchase
