## What it is
A curated awesome-list of open-source and commercial data labeling and annotation tools for machine learning datasets. It catalogs tools for annotating images, video, audio, and 3D/LiDAR data with categories like bounding boxes and semantic segmentation.

## Use cases
- find an open source tool to label images for object detection
- compare data annotation tools for training computer vision models
- discover tools for annotating video or audio datasets
- find a semantic segmentation labeling tool
- find annotation software for LiDAR or 3D point clouds
- find collaborative or crowdsourced labeling platforms

## When to choose
- you are surveying the landscape of data labeling tools before picking one
- you need a quick reference of annotation options across modalities like image, video, audio, and 3D

## When to avoid
- you need a working annotation tool itself rather than a list of links
- you need maintained, guaranteed-current recommendations - the list may contain outdated or abandoned projects
