What is OCR Confidence Score?
A 0–100 score an OCR engine assigns to each recognized character or word, indicating how certain it is.
OCR engines output a confidence score per character, word, or line. Low-confidence regions usually correspond to blurry scans, unusual fonts, or handwritten text. Workflows use confidence thresholds to flag content for human review instead of trusting it blindly.
