## What it is
BlockNote is an open-source, block-based rich text editor library for React, built on ProseMirror and TipTap, offering a Notion-style editing experience with a polished out-of-the-box UI. It supports custom blocks, real-time collaboration via Yjs, and optional AI-assisted editing through dual-licensed XL packages.

## Use cases
- add a Notion-style rich text editor to a React app
- build a block-based document editor with drag-and-drop blocks
- implement real-time collaborative text editing with Yjs
- create custom block types in a WYSIWYG editor
- add slash menus and formatting toolbars without building from scratch
- embed a polished text editor in a knowledge base or note-taking app

## When to choose
- you want a modern block-based editor with minimal setup in React
- you need real-time collaboration and offline-first editing out of the box
- you want a type-safe, extensible editor API without learning ProseMirror internals
- you need a fully styled editor UI that works immediately

## When to avoid
- you need a plain non-block rich text editor with full low-level control
- your project does not use React and you want batteries-included UI (headless/vanilla JS is more work)
- you need AI editing, multi-column layouts, or PDF/Docx export in a closed-source app without a commercial license
- you need a mature editor for a framework other than React
