# Crop Auto-Annotation

Crop Auto-Annotation, also known as Interest Area Auto-Annotation, in Unitlab Annotate automatically annotates your data in the selected areas using either built-in AI models or your own models (BYO).  You simply identify an Interest Area and let the AI models annotate the data for you.

### Key Features

* **Accurate Annotation:** Crop Auto-Annotation can annotate more accurately than Batch Auto-Annotation because you guide it on where to annotate, rather than annotating the entire image. 
* **Flexibility:** You can bring your own pre-trained models (BYO) by integrating them with Unitlab Annotate. Learn how to integrate your AI models with Unitlab Annotate on the [Model Integration](https://docs.unitlab.ai/ai-models/model-integration) page.

### How to use?

To use Crop Auto-Annotation, make sure you select an AI model for your project while creating it. As mentioned earlier, you can integrate your own pre-trained AI model instead of using Unitlab's built-in AI models. The process of creating the project follows the same steps as those guided in the "[Setup a Project](https://docs.unitlab.ai/project-management/setup-a-project)" section.

If you select an AI model for your project during its creation, you see this tool <img src="https://1366014570-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FVY6yJqW9wWHP6u0XYu5Q%2Fuploads%2FiKsVl64Lk6Ooh3p5SQLk%2Fimage.png?alt=media&#x26;token=71c7a19a-2ff1-4403-8c4c-8fc90a0a5111" alt="" data-size="line">  in the Unitlab Annotate toolbar when you open an image for annotation.

### **Review and Refine Annotations**&#x20;

Carefully review the generated annotations after using auto-annotation tools to ensure their accuracy in Unitlab Annotate. It's important to closely examine each annotation for correctness and consistency, making adjustments as needed to guarantee the highest quality of data for your projects.
