## Parseur

Parseur solves the copy-paste problem teams face when information arrives as PDFs, scans or email bodies. You forward a document to a dedicated mailbox, drag it into the app, or push it through the API, and Parseur identifies the document type, extracts the fields you named in plain English, and normalizes and validates each one before export. Because new layouts are handled by the AI engine rather than a hand-built template, a vendor changing its invoice format does not break your workflow.

Outputs are designed to land where your team already works: Excel and CSV downloads, Google Sheets, webhooks, or thousands of applications through Zapier, Make and n8n. The platform also keeps a full audit trail so every processed document can be traced back to the record it produced, with alerts whenever a document needs a human look.

The service is aimed at operations, finance, property, logistics, retail and HR teams who process high volumes of structured paperwork. It is EU-hosted, states compliance with GDPR, CCPA and PDPA, is SOC 2 Type II compliant with HIPAA in progress, and applies TLS 1.2+ encryption in transit and AES-256 at rest. A free tier includes a monthly page allowance, and paid plans scale with volume.

**Pricing & Plans:** Free to start with a monthly page allowance included, then pay-as-you-grow plans that scale with document volume and features. Enterprise pricing is available on request.

- **Vision AI and Text AI extraction:** Name the fields you want in plain English and the AI pulls them from clean digital PDFs, blurry scans and email bodies, adapting to new layouts automatically.
- **Multiple document intake channels:** Forward documents to a dedicated email address, drag and drop them in the app, or push them in via the API, webhooks or automation platforms.
- **OCR for scans and images:** Character recognition converts photographed receipts and scanned paperwork into machine-readable text before extraction.
- **Normalization and validation:** Format, clean and validate every extracted field so totals, dates and IDs arrive consistent rather than as raw strings.
- **Exports and 1,000+ integrations:** Download as Excel, CSV or JSON, or send parsed data in real time to Google Sheets, CRMs, ERPs and thousands of apps through Zapier, Make and n8n.

**Strengths:** Handles messy real-world inputs including blurry scans and emails, not just clean PDFs; No template building required for new layouts when using the AI engines; Broad integration coverage through Zapier, Make, n8n and a documented API; Strong compliance posture with EU data residency, SOC 2 Type II and GDPR alignment

**Limitations:** Pricing scales with page volume, so very high-throughput teams need a custom quote; Extraction accuracy still depends on document legibility and field naming; Advanced validation logic has a learning curve for non-technical operators

## 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
