Bad inputs
- Expecting OCR output from the checker.
- Using it to correct scan quality.
- Skipping review when the OCR result will be reused in a formal document.
Output checklist
- Confirm OCR is needed instead of text extraction.
- Review likely blockers before running PDF OCR.
- Plan a manual check of names, totals, dates, and line breaks.
Failure modes
- Low contrast and rotated scans can still produce weak OCR.
- Language and handwriting issues require manual review.
- Readiness signals do not predict every OCR error.
Runtime limits
- Browser-local checker.
- No OCR is run.
- Use before server-backed OCR when quality matters.
