Iteration Layer vs Azure Document Intelligence
Azure Document Intelligence uses pre-built models and custom training where a schema is enough.

Why developers switch from Azure Document Intelligence
Azure requires training custom models before you can extract data from new document types.
Schema-defined extraction, no training
Azure requires choosing a pre-built model (invoice, receipt, ID) or training a custom one on labelled documents. We skip the model entirely: define the fields you want, send your document, get typed JSON back.
17 typed field types, not raw text
Pre-built Azure models return field values as strings. We return typed results — dates as ISO dates, currencies as amount-plus-symbol objects, IBANs validated, addresses structured. No post-processing needed.
No Azure subscription required
Azure Document Intelligence requires an Azure subscription, resource groups, and managed identity configuration. We are a plain HTTP API — one endpoint, one API key.
