理想情况下，富文本编辑器应当生成干净、语义明确的文档，同时又要便于用户理解。ProseMirror 试图弥合两者之间的差距：一端是像 Markdown 或 XML 那样显式、无歧义的内容，另一端是传统的所见即所得（WYSIWYG）编辑器。
Rich content editors should, ideally, produce clean, semantically meaningful documents while still being easy for users to understand. ProseMirror tries to bridge the gap between editing explicit, unambiguous content like Markdown or XML, and classical WYSIWYG editors.
为此，它针对比纯 HTML 约束更多、结构更严谨的文档，实现了一套所见即所得风格的编辑界面。你可以自定义编辑器所创建文档的形状与结构，并根据应用的需要对它进行调整。
It does this by implementing a WYSIWYG-style editing interface for documents more constrained and structured than plain HTML. You can customize the shape and structure of the documents your editor creates, and tailor them to your application's needs.
