Why output quality differs

AreaTypical extractionUnpapered approach
Scanned PDFsOften returns noisy OCR with broken lines.Reconstructs readable sections and cleaner text.
TablesRows collapse into plain text blocks.Preserves row/column relationships for downstream use.
Multi-column docsReading order can become scrambled.Improves sequence reconstruction for better readability.
Output formatsUsually one plain output format.Exports markdown, txt, and json.

Common failure modes to watch for

  • Skewed or low-resolution scans can reduce OCR quality.
  • Complex merged cells may need manual table cleanup in edge cases.
  • Heavily stylized forms can produce partial text loss across tools.
