A rich text editor enables users to format content with bold, italics, underlining, lists, links, colors, and embedded media—much like a mini word processor inside an app. It supports WYSIWYG (What You See Is What You Get) functionality, ensuring that users preview final formatting in real-time. Essential for apps involving content creation, blogging, messaging, or note-taking, a rich text editor improves user engagement and expression. Features like undo/redo, custom styles, and Markdown/HTML output enhance flexibility. Ideal for both web and mobile, this tool can be tailored for user-generated content, making app interfaces more interactive and user-friendly.
