BlockNote
BlockNote is an open source, block-based rich text editor for React that offers a polished, Notion-style user experience with minimal setup. It comes with built-in UI components like menus and toolbars, which are fully customizable. It supports drag-and-drop functionality, allowing users to organize content into blocks that can be nested or rearranged. Developers can extend the editor with custom blocks, schemas, and plugins, benefiting from first-class TypeScript support for type safety and autocompletion. BlockNote enables real-time collaboration using Yjs, with support for providers like Liveblocks and PartyKit, allowing multiple users to edit documents simultaneously. It also supports theming, markdown, and HTML conversion, and can be used with vanilla JavaScript for non-React projects. Built on top of ProseMirror and TipTap, BlockNote simplifies the process of adding a rich text editor to applications, eliminating the need to build interface elements from scratch.

VisualEditor
The VisualEditor project by the Editing team aims to create a reliable rich-text editor for MediaWiki. VisualEditor is available as a MediaWiki extension using the Parsoid project to supply HTML+RDFa; however, its core implementation can be run without any of MediaWiki, Parsoid, or Node.js. As of 2020, the visual editor is available to all users at MediaWiki.org and on almost all Wikipedias and Wikivoyages. On most other Wikimedia projects and languages, it is available as an opt-in Beta Feature to logged-in users. VisualEditor is only available in some namespaces, including the main namespace, but generally not in discussion or template namespaces. The decline in new contributor growth was viewed as the single most serious challenge facing the Wikimedia movement. VisualEditor was built with the goal of removing avoidable technical impediments associated with Wikimedia's editing interface, as a necessary pre-condition for increasing the number of Wikimedia contributors.
