A rich text editor for React, built on Meta's Lexical, for developers building AI apps: chat composers, Markdown documents and agent-driven editing.
Table of contents
Lobe Editor (@lobehub/editor) is a drop-in rich text editor for React apps that talk to AI, from chat input boxes to full documents.
- Ready for chat — A chat composer with slash commands,
@mentions, attachments and a send button, ready to drop in - Markdown in, Markdown out — Type Markdown shortcuts, paste Markdown, and get clean Markdown or JSON back
- Let AI edit safely — Models can change the document while users review and accept or reject each change
- Rich content — Tables, code blocks, math, images, files, links, lists and collapsible sections
- Works beyond the browser — Process content on the server, render it read-only (SSR-friendly), and collaborate in real time
- AI-native —

$ bun add @lobehub/editor
# or
$ pnpm add @lobehub/editorRequires React 19 and the peer dependencies react, react-dom, @lobehub/ui and motion.
A minimal editor with lists, links and code blocks:
import { ReactCodeblockPlugin, ReactLinkPlugin, ReactListPlugin } from '@lobehub/editor';
import { Editor, useEditor } from '@lobehub/editor/react';
export default function MyEditor() {
const editor = useEditor();
return (
<Editor
editor={editor}
placeholder="Type / for commands..."
plugins={[ReactListPlugin, ReactLinkPlugin, ReactCodeblockPlugin]}
onTextChange={(editor) => {
console.log(editor.getDocument('markdown'));
}}
/>
);
}Next steps:
- Editor — props, plugins, mentions and slash menus
- ChatInput — build a chat composer
- Components — all components, plugins and renderers
Lobe Editor is built for AI-assisted development. The docs site publishes machine-readable references, so agents use real props and APIs instead of guessing.
| Resource | What it does |
|---|---|
| Agent Skills | editor.lobehub.com/skills.md — setup, workflow and an index of every component and plugin. Give this URL to your agent in Cursor, Claude Code, Codex and others |
| llms.txt | editor.lobehub.com/llms.txt — structured page index with descriptions and outlines for LLMs |
| Markdown docs | Every docs page has a .md version, e.g. Editor and ChatInput |
Copy this prompt to your agent:
Read https://editor.lobehub.com/skills.md and follow it to add @lobehub/editor.
Works with Cursor, Claude Code, Windsurf, GitHub Copilot and any tool that can read llms.txt or fetch a URL.
- AI chat apps that need a rich input box with mentions, commands and attachments
- AI writing and knowledge tools where a model edits documents and users review the changes
- Backends that convert or render editor content without a browser
- Collaborative editors that sync documents in real time
