The Intelligent.OCR package provides advanced OCR capabilities. It enables robots to extract valuable information from unstructured documents, empowering them to make informed decisions in collaboration with human operators.

## Available activities

The following table lists the activities that are included in the Intelligent.OCR package and allow you to create long-running workflows and generate actions in Action Center.

| Activity | Description |
| --- | --- |
| [Create Document Classification Action](https://docs.uipath.com/action-center/automation-suite/2024.10/user-guide/create-document-classification-action) | Allows you to generate a Document Classification action in Action Center. |
| [Wait For Document Classification Action And Resume](https://docs.uipath.com/action-center/automation-suite/2024.10/user-guide/wait-for-document-classification-action-and-resume) | Acts as a control point in the workflow, suspending its execution until a specific Document Classification action is completed in Action Center. |
| [Create Document Validation Action](https://docs.uipath.com/action-center/automation-suite/2024.10/user-guide/create-document-validation-action) | Creates a Document Validation action in Action Center. This capability allows automation workflows to cross with human validation, ensuring accurate data processing. |
| [Wait For Document Validation Action And Resume](https://docs.uipath.com/action-center/automation-suite/2024.10/user-guide/wait-for-document-validation-action-and-resume) | Serves as a waiting mechanism, holding the current workflow until a designated Document Validation action is fulfilled in Action Center. |
