In their own words
ProseMirror
ProseMirror is a toolkit for developers building rich-text editors on the web. It supports structured documents through a WYSIWYG-style interface while letting applications define document shape and content. Instead of treating a document as an HTML blob, it gives application code control over a custom data structure. Schemas and plugins provide ways to customize that structure and extend editor behavior. Four core modules handle the document model, editor state, view, and transformations; additional modules offer commands, key bindings, undo history, input macros, collaboration, and a basic schema. Multiple people can edit together in real time. Examples cover Markdown, image uploads, custom schemas, menus, code editors, footnotes, and track changes. ProseMirror is free, open source, and legally usable commercially; it can be self-hosted and is installed through npm. It works in recent Firefox, Chrome, Safari, and Edge versions, as well as Internet Explorer 11. It is a modular toolkit rather than a ready-made editor component, and implementation generally involves a bundler.
