## Description

CKEditor 5 is a modular rich text editor framework and JavaScript UI component used to build customizable visual editors. It serves as a system for generating HTML or Markdown content, providing both full rich-text editor components and restricted inline editor components for web applications.

The framework includes a collaborative editing engine for real-time simultaneous editing, change tracking, and threaded commenting. It features an AI text assistant for polishing, rewriting, and generating content, as well as a document export engine that transforms rich text into PDF and Word files.

The system covers a broad range of capabilities including media embedding, complex content structuring, and automated text correction. It provides tools for interface localization, programmatic extensions, and accessibility compliance validation, while supporting data persistence through background saving and cloud file management.
