This is Syncfusion's production-grade React rich text editor with everything you'd expect from an enterprise component: WYSIWYG and Markdown modes, media insertion, AI assistant integration, slash commands, mentions, and Word/PDF import/export. The module injection system lets you cherry-pick features to keep bundles lean. It's heavily featured but requires their full CSS stack and comes with the complexity of a mature commercial product. If you need form validation, paste cleanup, accessibility compliance, and deep customization out of the box, this handles it. For simpler use cases, the setup overhead might be more than you need.
