MarkText Markdown Editor

MarkText is a free and open-source Markdown editor with a real-time preview interface, providing a distraction-free writing environment that renders Markdown as formatted text as you type. Created by Jocs in 2018, with over 48,000 stars as of 2026, MarkText is one of the most popular Markdown editors available. Key features include: live preview (WYSIWYG editing mode that renders Markdown formatting in real-time, showing bold, italic, headers, lists, code blocks, tables, and images as formatted content without showing Markdown syntax), source code mode (toggle between WYSIWYG and raw Markdown source code editing for fine-grained control), CommonMark and GitHub Flavored Markdown (full support for CommonMark specification, GitHub Flavored Markdown, math formulas via KaTeX, and task lists), multiple tabs (open and edit multiple Markdown files simultaneously in separate tabs), themes (built-in light and dark themes with customizable CSS themes and syntax highlighting themes for code blocks), image handling (paste images from clipboard with automatic upload to configured cloud storage or save to local folder, drag-and-drop image insertion, and image resizing), export formats (export documents to HTML and PDF with customizable styling, plus export to Markdown with embedded images), focus mode (dim or hide paragraphs other than the current one for distraction-free writing), typewriter mode (keep the current line centered vertically on the screen for comfortable long-form writing), tables (visual table editor with keyboard navigation, column and row insertion, and Markdown table syntax export), diagrams (render Mermaid diagrams, sequence diagrams, flowcharts, and Gantt charts in code blocks), shortcuts (extensive keyboard shortcuts for all formatting and navigation operations), and cross-platform (Windows, macOS, and Linux via Electron).
