Microsoft's enterprise OCR and document processing service combining traditional OCR with deep learning for layout analysis, table extraction, key-value recognition, and custom model training.
Microsoft's service that reads and extracts data from forms, invoices, and documents — automates paperwork processing with industry-leading table extraction.
Azure AI Document Intelligence (formerly Form Recognizer) is Microsoft's cloud OCR and document processing service that combines traditional OCR with deep learning models for layout analysis, table extraction, key-value pair recognition, and document classification. It's the most feature-rich of the major cloud document processing services and benefits from Microsoft's decades of investment in OCR technology.
The service offers prebuilt models for common document types (invoices, receipts, W-2 forms, contracts, health insurance cards) that extract specific fields without custom training. The invoice model, for example, extracts vendor name, invoice number, line items, totals, and payment terms with high accuracy. For custom document types, the custom model training feature lets you label 5-10 example documents and train a model that extracts your specific fields.
The general layout analysis model is where Document Intelligence excels for AI applications. It returns detailed document structure: text lines with bounding boxes, paragraph groupings, table structures with cell-level precision, heading detection, and reading order. The table extraction is industry-leading — it correctly handles merged cells, spanning headers, nested tables, and tables that span multiple pages.
Document Intelligence supports the prebuilt-read model for high-volume OCR, the prebuilt-layout model for structural analysis, and specialized prebuilt models for specific document types. The newer models also provide markdown-formatted output, making integration with LLM pipelines significantly easier.
Pricing is per-page with rates varying by model. The Read model starts at ~$1.50 per 1,000 pages for basic OCR. The Layout model costs $10-50 per 1,000 pages for structural analysis. Prebuilt models run $10-100 per 1,000 pages depending on document type. Custom models cost more but offer domain-specific extraction.
The Azure ecosystem integration is a double-edged sword. If you're on Azure, Document Intelligence integrates seamlessly with Blob Storage, Cognitive Search, and Azure OpenAI Service. If you're on AWS or GCP, you're adding a cross-cloud dependency. The SDK support is excellent for .NET and Python, good for Java, and adequate for JavaScript.
Document Intelligence is the strongest choice when you need accurate table extraction, custom field extraction from specific document types, or are already invested in the Azure ecosystem. For simpler OCR needs or if you want to avoid cloud vendor dependency, open-source alternatives like Docling offer competitive quality for common use cases.

Azure AI Document Intelligence is Microsoft's enterprise document processing service with industry-leading table extraction and prebuilt models for common business documents. The markdown output mode makes it particularly valuable for RAG and LLM pipeline integration. Best for enterprises on Azure needing accurate, compliant document processing at scale.
Extracts detailed document structure including text lines with bounding boxes, paragraphs, tables with cell-level structure, headings, reading order, and page dimensions. Returns results as structured JSON or markdown.
Use Case:
Processing a multi-page contract to extract table structures, heading hierarchy, and reading order for a legal document analysis system.
Cell-level table extraction with support for merged cells, spanning headers, row/column headers, nested tables, and tables spanning multiple pages. Each cell includes content, row/column indices, and bounding boxes.
Use Case:
Extracting complex financial tables from annual reports where accurate cell-to-header mapping is critical for automated data analysis.
Pre-trained models for invoices, receipts, W-2 tax forms, ID documents, contracts, health insurance cards, and more. Each model extracts document-specific fields with high accuracy out of the box.
Use Case:
Automating accounts payable by extracting vendor, amount, line items, and payment terms from incoming invoices without custom model training.
Train custom extraction models by labeling 5-10 example documents in Document Intelligence Studio. Supports both fixed-template and free-form document types with transfer learning for reduced data requirements.
Use Case:
Training a model to extract specific fields from a company's proprietary report format that no prebuilt model covers.
Returns document content as clean markdown with headers, tables, and paragraph structure preserved. Eliminates JSON-to-text post-processing for LLM pipeline integration.
Use Case:
Feeding extracted document content directly into an Azure OpenAI prompt for summarization or Q&A without custom format conversion code.
Classifies documents into categories (invoice, contract, form, letter) and routes them to appropriate extraction models. Supports custom classification models for domain-specific document types.
Use Case:
Building a document intake system that automatically classifies uploaded files and routes each type to the correct extraction pipeline.
$1.50 per 1,000 pages
$10 per 1,000 pages
$10-100 per 1,000 pages
$50+ per 1,000 pages plus training costs

Azure AI Document Intelligence works with these platforms and services:
We believe in transparent reviews. Here's what Azure AI Document Intelligence doesn't handle well:
Document Intelligence has better table extraction (especially for complex tables with merged cells and spanning headers) and more prebuilt document models. Textract has simpler pricing and tighter AWS integration. For complex documents with tables, Document Intelligence typically wins. For simple OCR within AWS environments, Textract is more natural.
With the Read model (basic OCR): ~$15. With the Layout model (tables + structure): ~$100. With prebuilt models (invoices, receipts): ~$100-1,000 depending on document type. Custom models: ~$500+. Exact costs depend on features used and whether you're on a commitment tier.
Yes — you need an Azure account and a Document Intelligence resource, but no other Azure services. The REST API and Python/JS/.NET SDKs work from any environment. However, you still pay Azure and are subject to Azure's SLA.
The Layout model can return document content as clean markdown with headers, tables, and paragraphs preserved. This markdown can be fed directly into LLM prompts for summarization, Q&A, or analysis without writing custom JSON-to-text conversion code. It's particularly useful for RAG pipeline ingestion.
