Editor's Summary · OCR Software
Ask what happens to the output. If a person reads it, you want searchable documents and Adobe Acrobat or Readiris is enough. If a system consumes it, you want structured extraction with named fields, and that is a different product entirely.
For structured work, start with your document type. Invoices and receipts are solved problems — Rossum, Veryfi, Docsumo, Klippa and Nanonets are trained for them and need little setup. Resumes are their own hard problem, and Affinda is the specializt. For everything else, Google Document AI and Azure AI Document Intelligence give general capability with prebuilt models and custom training.
The consistency question decides the approach. Fixed layouts favor rule-based parsing — Docparser is predictable and debuggable. Variable layouts need AI extraction, and Sensible's per-field mix of deterministic rules and LLM inference is the pragmatic middle.
Check whether humans review low-confidence documents behind the scenes: it affects turnaround and privacy, and Veryfi is explicit that it does not.

How to choose OCR Software
Test with your worst documents, not your best — accuracy on clean scans is uniformly high and tells you nothing. If your document type is common (invoice, receipt, ID, resume), a specialized extractor will beat a general service and need far less configuration. Check pricing structure carefully: per-page cloud pricing that is trivial at pilot volume can become the largest line in a process at production volume, and a self-hosted engine may be cheaper despite worse accuracy.
Our research is independent and data-backed. We review thousands of tools and use real buyer signals — without the hype.
