Iteration Layer vs Azure Document Intelligence
Azure Document Intelligence extracts fields from pre-built models — not general markdown from any document.
Why developers switch from Azure Document Intelligence
Azure outputs model-specific field values, not clean markdown — and requires model selection or training first.
Markdown from any document, no model needed
Azure requires choosing a pre-built model (invoice, receipt, ID) or training a custom one. We take any document — PDF, image, or Office file — and return clean markdown immediately, without model selection.
Image description included
When you send an image file, we return both OCR markdown and a natural language description of the image content. Azure returns structured field values tied to a specific document model, not a readable markdown representation.
No Azure subscription required
Azure Document Intelligence requires an Azure subscription, resource groups, and managed identity configuration. Iteration Layer gives you a direct HTTP API with shared credits, EU processing, n8n, and MCP.
Feature-by-feature comparison
We went through the docs so you don't have to. Here's how every feature compares — including the ones where we're not the better choice.
| Feature | Iteration Layer | Azure Document Intelligence |
