Our Methodology

How we test, score, and review OCR and document extraction software.

Our Test Document Set

Every tool we review is tested against the same standardized set of real-world documents:

  • 50 invoices — from 30+ different vendors, varying formats, languages, and quality levels
  • 20 receipts — retail, restaurant, and service receipts (digital and photographed)
  • 10 bills of lading — shipping documents with complex table structures
  • 10 bank statements — multiple banks, varying layouts
  • 10 miscellaneous — contracts, forms, medical documents

Documents include clean digital PDFs, scanned documents at various DPI levels, and photographs taken with smartphones. This represents real-world conditions.

Scoring Rubric

Each tool is scored on six dimensions with the following weights:

  • Accuracy (25%) — Field-level extraction accuracy on our test set.
  • Ease of Use (20%) — Time to first extraction, learning curve, documentation quality.
  • Pricing Value (20%) — Cost per page at three volume tiers (100, 1,000, 10,000 pages/month).
  • Integration Depth (15%) — API quality, native integrations, webhook support.
  • Document Versatility (10%) — Range of document types and multi-language capability.
  • Support & Docs (10%) — Response time, support channels, knowledge base quality.

Review Updates

We re-test every tool quarterly. When a tool releases a major update, we re-test sooner. Each review page shows the last update date.
