Open Markdown like a document: fast, clean, and distraction-free. Moji is a lightweight reader and editor for Windows, macOS, and Linux, with live preview, Mermaid diagrams, and PDF, HTML, and PNG export.
Hey Product Hunt 👋
I built Moji because opening a Markdown file often felt more complicated than it should.
Most of the time, I don't want to launch a full IDE just to read a `.md` file. I wanted Markdown to behave more like a PDF:
double-click → read → close.
That simple idea became Moji.
Moji is a free and open-source desktop app for Windows, macOS, and Linux. It focuses on making Markdown pleasant to read, while still giving you an editor when you need one.
Over time, I added things like:
• live editor + preview with synchronized scrolling
• Mermaid diagrams
• LaTeX math
• tabs and outline navigation
• search and replace
• HTML, PDF, and PNG export
• support for large Markdown files
• 15+ interface languages
It's built with Electron, React, TypeScript, CodeMirror 6, and Mermaid, and the entire project is MIT licensed.
What started as a small tool for myself has grown much more than I expected, but I'm still trying to keep the original idea at the center of it: Markdown should be easy to open and read.
I'd love to hear how you use Markdown today and what you'd like to see in Moji next.
