## 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

## Sortio

Sortio addresses a problem almost everyone shares: folders like Downloads, Documents, and shared drives fill up with inconsistently named files that are painful to sort by hand. Instead of dragging files around, you type an instruction such as "rename documents by date and type, then file them by trip" and Sortio interprets it. It inspects each file's actual contents — text, dates, amounts, names, image metadata — generates a clean, consistent filename, and moves the file to the folder it belongs to, creating missing folders along the way.

The workflow is built around safety and transparency. Before anything happens you get a preview of every proposed rename and move, and any pass can be undone. Everything runs locally, and Sortio also supports a local LLM (for example via Ollama) or bringing your own API key so sensitive files never have to leave your machine. Rule-based sorting is free and unlimited, while AI sorting runs against a monthly allowance.

Sortio is aimed at freelancers, lawyers, realtors, bookkeepers, consultants, project managers, and home archivists who must file large batches of documents against clients, matters, properties, or projects. It runs on macOS 11+, Windows 10/11, and Linux, and the community frequently votes on which features get prioritized next.

**Pricing & Plans:** Freemium structure with a free tier that includes a one-time AI trial allowance, unlimited rule-based sorting, and up to 5 rules/3 Spaces. Pro is $14.99/month or $99/year (~$8.25/mo) with a monthly AI allowance of up to 5,000 files per run, unlimited Spaces and automations, and unlimited renaming. Team is $290/seat/year ($29/seat/month) with doubled pooled AI allowance and shared workspaces; Enterprise starts around $50/seat/month with SSO, audit logs, and centralized billing. Local LLM/BYOK usage is unmetered and consumes no allowance.

- **Prompt-driven sorting:** Describe the result you want in plain English and Sortio plans the renames and folder moves for you.
- **Content-aware renaming:** Reads inside each file to build meaningful names such as date, vendor, amount, or person, instead of leaving cryptic originals.
- **Preview and undo:** Every move is shown before it happens, and any sorting pass can be rolled back completely.
- **Privacy-first local processing:** Files stay on your machine, with local LLM and bring-your-own-key options on every plan.
- **Rules, Spaces, and watch folders:** Set up free unlimited rule-based sorting plus monitored folders that auto-sort files as they change.

**Strengths:** Works offline with strong privacy controls, including local LLM and BYOK support; Preview-then-apply workflow with full undo removes the risk of mass-moving files; Free tier with unlimited rule-based sorting and a real AI trial allowance; Available on macOS, Windows, and Linux with an active, feedback-driven community

**Limitations:** AI sorting on the free tier is limited to a one-time trial allowance; The best results depend on writing a clear, well-scoped prompt; Desktop-only — there is no web app or mobile version
