## What it is
Retext is a JavaScript library that transforms natural language into concrete syntax trees (CSTs) and lets plugins inspect and change that structured prose. It is part of the unified collective and runs on the server, client, and Deno.

## Use cases
- check spelling in text programmatically
- fix typography like smart quotes in prose
- check readability of articles
- lint natural language text for redundant phrases
- parse English text into a syntax tree
- build custom natural language processing plugins

## When to choose
- you want to process or lint prose as structured data in JavaScript
- you need a plugin-based pipeline for natural language transformations
- you want to run text processing on server, client, or Deno

## When to avoid
- you need heavy statistical NLP or machine learning models
- you only need simple regex-based text replacement
- you work outside the JavaScript ecosystem

## Facets
- artifact type: library
- maturity: active
- function: nlp, parser, plugin-system
- domain: developer-tools, text-editors
- platform: browser
