A company must extract structured data — invoice number, line items, totals — from thousands of vendor invoices. Which service extracts structured fields from documents?
A.Azure AI Vision OCR alone
OCR gives text, not field-level structure — invoice fields need Document Intelligence.
B.Azure AI Document Intelligence
Prebuilt invoice models extract named fields/tables. Correct.
C.Azure AI Custom Vision
Custom Vision classifies/detects objects in images — not form fields.
D.Azure AI Search
AI Search indexes content for querying — not field extraction.
Why this answer
Document Intelligence (formerly Form Recognizer) extracts STRUCTURED data — key-value pairs, tables, line items — from documents using prebuilt models (invoices, receipts, IDs) or custom-trained ones. OCR gets raw text; DI understands document structure and semantics.
