## What it is
YEDDA is a lightweight desktop GUI tool for manually annotating text spans with entity, chunk, or event labels, built with Python's tkinter. It supports efficient shortcut-key annotation, batch command annotation, intelligent label recommendation, and administrator analysis of annotation results.

## Use cases
- annotate named entities in text for NER training data
- label text spans with custom entity categories using keyboard shortcuts
- create training data for sequence labeling models
- collaboratively annotate text corpora across Windows, Linux, and macOS
- review and analyze annotator productivity and results as an admin
- export annotated text to sequence format for machine learning pipelines

## When to choose
- you need a free, offline desktop tool for manual text span annotation
- you want fast shortcut-driven annotation for NER or chunking datasets
- you work with multiple languages including Chinese and emoji
- you need admin analytics on annotation quality and speed

## When to avoid
- you need web-based collaborative annotation with real-time multi-user sync
- you require annotation of images, audio, or other non-text media
- you want modern actively maintained tooling with recent updates
- you need integration with cloud annotation pipelines or APIs
