## What it is
A Canvas/SVG-based WYSIWYG rich text editor library for the browser, offering Word-like paginated editing with tables, controls, watermarks, LaTeX formulas, and PDF/Word import-export via plugins. It ships as a core npm package with a fully typed TypeScript API, extensible menus, plugins, and lifecycle/event hooks.

## Use cases
- embed a word-like paginated rich text editor in a web app
- build a document editor with form controls and placeholders
- generate PDFs from editable documents in the browser
- create EMR/medical record forms with cascading form controls
- add watermarks, headers, footers, and page numbers to web documents
- import and export docx files in a web editor
- render LaTeX formulas inside rich text documents

## When to choose
- you need Word-like pagination and print-ready layout in the browser
- you want a lightweight JSON document model with full TypeScript types
- you need form controls, revision tracking, or comments in a document editor
- you want to self-build toolbars/menus on top of a core editor engine

## When to avoid
- you need a simple markdown or plain-text editor
- you want a batteries-included editor with a prebuilt toolbar out of the box
- you need server-side or native (non-browser) editing
- your project requires a large ecosystem of community plugins like ProseMirror or Slate
