# Labeling Classes

Labeling classes define the categories and annotation structures used during the labeling process in Ango Hub. Each class is associated with a specific labeling tool and determines how annotators interact with the data while creating annotations. Ango Hub supports a wide range of labeling tools designed for different data types and annotation needs, such as spatial annotations (e.g., bounding boxes or polygons), classification tools, text-based inputs, and relationship annotations. ## List of Labeling Tools on Ango Hub ### Tools
