How to Compare OCR Tools in 2026: Checklist and Test Plan
Published OCR scores rarely match your documents. Use this checklist to shortlist tools, then run the same few files through each one.
Languages and scripts
- Check that your exact script is supported, including right-to-left text, diacritics and mixed-language pages.
- Test one real page in each script before you rely on a tool.
Input and output
- Which inputs does it take: photos, screenshots, scanned PDFs, native PDFs?
- Which outputs: plain text, Word, searchable PDF, structured data? Check whether Word output keeps layout or only the text.
Privacy and retention
- Find out where files are stored, how long, and whether they are used for training.
- Look for encryption in transit and at rest and a documented deletion period.
Cost and limits
- Compare free limits, per-page pricing and file-size limits against your real volume.
- Check what needs an account and what does not.
A simple test plan
- Pick five to ten files that include your hardest cases.
- Run each through every tool, then proofread names, numbers and dates against the originals.
- Choose on the results you saw, not on a vendor average.
