## What it is
Natural is a general natural language processing library for Node.js offering tokenizing, stemming, part-of-speech tagging, sentiment analysis, classification, and string distance utilities. It also provides WordNet integration, phonetic matching, and TF-IDF, with TypeScript support.

## Use cases
- tokenize and stem text in node
- sentiment analysis of reviews
- classify text with a naive bayes classifier
- compute string similarity with levenshtein or jaro-winkler distance
- look up word definitions with WordNet
- part-of-speech tagging for English text
- build a tf-idf search over documents
- phonetic matching of names with metaphone

## When to choose
- you need classic statistical NLP in a Node.js or JavaScript project without heavy ML dependencies
- you want a broad toolkit of text utilities in one MIT-licensed package
- you need lightweight classifiers, stemmers, or string distance metrics server-side

## When to avoid
- you need modern transformer-based or deep learning NLP models
- you work outside Node.js
- you need high-accuracy state-of-the-art language understanding
