What is Azure AI Document Intelligence?

This content applies to: v3.1 (GA) | Latest version: v4.0 (preview) | Previous versions: v3.0 v2.1

Note

Form Recognizer is now Azure AI Document Intelligence!

• As of July 2023, Azure AI services encompass all of what were previously known as Cognitive Services and Azure Applied AI Services.
• There are no changes to pricing.
• The names Cognitive Services and Azure Applied AI continue to be used in Azure billing, cost analysis, price list, and price APIs.
• There are no breaking changes to application programming interfaces (APIs) or SDKs prior to and including v3.1. Starting from v4.0, APIs and SDKs are updated to Document Intelligence.
• Some platforms are still awaiting the renaming update. All mention of Form Recognizer or Document Intelligence in our documentation refers to the same Azure service.

Azure AI Document Intelligence is a cloud-based Azure AI service that enables you to build intelligent document processing solutions. Massive amounts of data, spanning a wide variety of data types, are stored in forms and documents. Document Intelligence enables you to effectively manage the velocity at which data is collected and processed and is key to improved operations, informed data-driven decisions, and enlightened innovation.

| ✔️ Document analysis models | ✔️ Prebuilt models | ✔️ Custom models |

General extraction models

General extraction models enable text extraction from forms and documents and return structured business-ready content ready for your organization's action, use, or development.

Read | Extract printed
and handwritten text.

Layout | Extract text, tables,
and document structure.

General document | Extract text,
structure, and key-value pairs.

Prebuilt models

Prebuilt models enable you to add intelligent document processing to your apps and flows without having to train and build your own models.

Invoice | Extract customer
and vendor details.

Receipt | Extract sales
transaction details.

Identity | Extract identification
and verification details.

Health Insurance card | Extract health insurance details.

Business card | Extract business contact details.

Contract | Extract agreement
and party details.

US Tax W-2 | Extract taxable
compensation details.

US Tax 1098 | Extract 1098 variation details.

Custom models

Custom models are trained using your labeled datasets to extract distinct data from forms and documents, specific to your use cases. Standalone custom models can be combined to create composed models.

Document field extraction models

✔️ Document field extraction models are trained to extract labeled fields from documents.

Custom generative | Build a custom extraction model using generative AI for documents with unstructured format and varying templates.

Custom neural | Extract data from mixed-type documents.

Custom template | Extract data from static layouts.

Custom composed | Extract data using a collection of models.

Custom classification models

✔️ Custom classifiers identify document types before invoking an extraction model.

Custom classifier | Identify designated document types (classes) before invoking an extraction model.
