Ideally, content editors should create documents that are both clean and semantically rich, while still being user-friendly. ProseMirror aims to connect the worlds of precise content editing, such as Markdown or XML, and traditional WYSIWYG editors. It achieves this by offering a WYSIWYG-style interface designed for documents that are more structured and constrained than standard HTML. Additionally, you can modify the format and organization of the documents generated by your editor to fit the specific requirements of your application. ProseMirror provides solid, foundational support for collaborative editing, enabling multiple users to work on the same document simultaneously. Its document schemas facilitate the editing of uniquely structured documents without the necessity of building a new editor from the ground up. The system's modular design ensures that you only load essential code, allowing for the replacement of components as needed. Furthermore, a flexible plugin system enables you to easily add extra features, enhancing the editor's capabilities. This versatility makes ProseMirror a powerful choice for developers seeking a customizable editing experience.
