## What it is
Trix is a WYSIWYG rich text editor for web applications, built by 37signals as a JavaScript custom element. It uses its own internal document model rather than relying on contenteditable's execCommand APIs, producing consistent HTML output with support for embedded attachments.

## Use cases
- add a rich text editor to a web app for writing messages and comments
- let users compose formatted articles or lists in the browser
- embed a WYSIWYG editor with attachment support in a form
- avoid cross-browser contenteditable inconsistencies in a text editor
- build a comment box with bold, italic, and list formatting
- integrate a rich text editor into a Rails or any JavaScript web application

## When to choose
- you need a dependable, production-proven WYSIWYG editor for everyday writing like messages, comments, and articles
- you want consistent, terse HTML output across all evergreen browsers
- you prefer a web-standards-based custom element that works with any bundler or framework
- you need built-in support for embedded attachments

## When to avoid
- you need complex document editing like tables, collaborative editing, or fine-grained layout control
- you want a fully customizable editor architecture with a plugin ecosystem (consider ProseMirror or Slate)
- you need a plain markdown or code editor rather than WYSIWYG formatting
