Why I Created Moji to Open Markdown Files Like PDFs
Short summary
Moji is an open-source desktop application for viewing and editing Markdown files as fully rendered documents, similar to opening a PDF. It supports tabs, Mermaid diagrams, LaTeX math, syntax highlighting, and export to HTML/PDF/PNG. The tool targets users who frequently read Markdown-based AI agent instructions, documentation, and project context files without needing a full IDE.
