## What it is
Editor.js is an open-source, block-style rich text editor for the web that outputs clean JSON instead of HTML markup. It is highly extensible, with each content block (paragraphs, headings, images, lists, etc.) provided by a separate plugin via a well-designed API.

## Use cases
- embed a block-based rich text editor in a web app
- store user-generated content as structured JSON instead of HTML
- build a CMS or blogging platform with a modern editing UI
- create custom editor block tools via a plugin API
- render editor content across web, mobile, and chatbots from one data format
- sanitize and validate rich content safely

## When to choose
- you need structured JSON content output rather than messy HTML
- you want a modern, block-style editing experience out of the box
- you need to extend the editor with custom block or inline tools
- you plan to reuse content across multiple platforms (web, mobile, AMP, bots)

## When to avoid
- you need a traditional single-contenteditable WYSIWYG producing HTML
- you require a full-featured document editor like Google Docs
- your project depends on non-JavaScript environments without a browser
