## What it is
CKEditor 5 is a modern JavaScript/TypeScript rich-text (WYSIWYG) editor framework with a modular plugin architecture, custom data model, and virtual DOM. It supports everything from simple text editing to Google Docs-style real-time collaboration, AI-assisted writing, and Word/PDF import-export.

## Use cases
- add a wysiwyg rich text editor to my web app
- embed a contenteditable editor with formatting toolbar in javascript
- build a google docs-like collaborative editing experience
- let users paste from word and excel with formatting preserved
- export editor content to pdf or word documents
- create a custom editor framework with plugins in typescript
- add comments and track changes to document editing
- integrate an ai writing assistant into a text editor

## When to choose
- you need a production-grade, actively maintained rich text editor with extensive features
- you want real-time or asynchronous collaboration with comments and track changes
- you need a modular framework to build custom editing experiences or plugins
- your users need Word/PDF import-export or paste-from-Office fidelity
- you want TypeScript support and modern bundler integration

## When to avoid
- you only need a lightweight markdown or plain-text editor
- you require a fully open-source license for premium features like collaboration or AI, which are commercial
- you need a mobile-native (non-web) text editing solution
- your project needs a minimal dependency footprint and cannot afford a large editor bundle
