OCR and documents

OCR reads text in images; document AI structures forms, tables, and layouts for downstream RAG or workflows.

Invoice/automation wins live here—and so do silent number errors. Always verify critical fields.

Detect text regions → recognize characters → optional layout/entity extraction → human review for high stakes. Pair with Course 09 for retrieval over PDFs.

OCR a receipt; check totals digit-by-digit.

⚠️ Myth: Pretty OCR text means correct amounts.

✓ Reality: Digit swaps are common; validate checksums/fields.
