AI OCR Enhancement — Fix OCR Errors with Claude AI

Standard OCR (Tesseract) converts images to text mechanically — it makes character-level errors that are hard to detect. AI OCR Enhancement adds a second pass: Claude reads the OCR output in context and corrects errors that no regex can catch (like 'rn' misread as 'm', or words split across lines incorrectly).

Common fixes include: wrong characters (0 vs O, l vs 1), merged words, incorrectly split words, wrong spacing, garbled passages from low-quality scans, punctuation errors, and inconsistent capitalisation from OCR misreads. The correction report shows a breakdown by category.

Yes. The correction report shows the total number of corrections, a category breakdown (wrong characters, merged words, spacing, etc.), and you can expand a panel to see the original OCR text alongside the corrected output.

Over 35 languages are supported, including English, Spanish, French, German, Chinese, Japanese, Korean, Arabic, Hindi, and more. Select the document language before processing for best results.

Tesseract is optimised for printed text. Handwriting recognition accuracy varies significantly. For clear, neat handwriting it can work, but cursive or mixed handwriting/print documents will have lower accuracy.

Yes. AI OCR Enhancement uses Claude AI for intelligent error correction, which requires a Pro plan. The standard OCR PDF tool (which adds a searchable text layer without AI correction) is available on all plans.

WhiskFile processes multi-page scanned PDFs with consistent AI correction across all pages. Processing time scales with document length — a 10-page PDF typically takes under a minute.

Yes. Select the document language from 35+ supported options before processing. The AI uses language context to correct errors more accurately. For mixed-language documents, select the primary language.

Yes. The AI is especially effective on low-quality scans where standard OCR produces many errors. It uses context and language understanding to reconstruct garbled passages that regex-based correction cannot fix.

Yes. Your PDF is processed on WhiskFile servers and deleted within 1 hour. Document content is never stored permanently or used to train AI models.

After processing, you see a detailed report showing: total corrections made, error categories (wrong characters, merged words, split words, spacing, punctuation), and a side-by-side comparison of original vs corrected text.

Yes. If your PDF already has an OCR text layer from another tool (Adobe, ABBYY, etc.), the AI will read and correct that existing text layer. You don't have to re-run OCR first.

OCR PDF adds a searchable text layer to scanned PDFs using Tesseract. AI OCR Enhance goes further — it runs OCR then uses Claude AI to fix the errors that Tesseract makes. Use OCR PDF for basic searchability, AI OCR Enhance when you need accurate, clean text.
