A Markdown Editor is a tool that allows users to write and format text using the Markdown language. Markdown is a lightweight markup language that uses plain text formatting syntax, making it easy to create structured documents without complex coding. Users can add headings, lists, links, and images simply by using specific characters, which makes it accessible for both beginners and experienced writers. Many Markdown editors come with features like live previews, syntax highlighting, and export options to various formats such as HTML or PDF. Popular examples of Markdown editors include Typora, Obsidian, and Visual Studio Code. These tools are widely used for writing documentation, notes, and web content due to their simplicity and efficiency.
