## What it is

ProseMirror is a toolkit for building rich text editors that joins Markdown-style structured content with WYSIWYG editing.

## What it’s for

To build your own editor, with a custom document schema, instead of starting from scratch.

## Benefits

- Real-time collaborative editing
- Extensible document schemas
- Modular core and plugin system

## Caveats

- Open source, with commercial use allowed; the page asks companies that profit from it to help fund maintenance
- It's a low-level, unopinionated library; you have to build the interface yourself
