Download MarkText Plus
MarkText Plus is a local Markdown editor for desktop systems. It opens plain text files and renders them with support for tables, footnotes, task lists, and math. The program includes a native Mermaid renderer for diagrams without a web view. Export options cover HTML, PDF, and Word formats. File handling includes encoding detection and atomic writes.
The application offers three editing layouts: source, preview, and split. Users can edit rendered blocks directly in preview mode. The slash menu and command palette speed up formatting and navigation. Find and replace works with regular expressions and whole words. Pasted URLs become Markdown links over selected text automatically.
Built with Flutter and Dart, MarkText Plus targets Windows, macOS, and Linux. The project started in 2025 and remains focused on speed and document fidelity. No account or network connection is required. All files stay on the local machine, and the editor watches for external changes to prevent accidental overwrites.
