MDX - The Markdown editor for people who don't write Markdown

by•
A WYSIWYG Markdown editor for the AI era.

Click-to-format math, citations, diagrams. Export to DOCX, PDF or HTML with a numbered bibliography. Optional Tab-to-complete ghost-writer uses your own API key. Local-first. No account. No telemetry. $15 one-time. macOS, Windows, Linux.

Hey Product Hunt 👋 I'm Vincent, the maker of MDX. Here's the moment that started this: I asked ChatGPT for some notes, it handed me back a .md file, and I sat there staring at ## Headings and **asterisks** thinking "why am I editing source code to fix a typo in a paragraph?" Every Markdown editor I tried fell into one of two camps: Source editors (Obsidian, Typora-ish, VS Code) — you type the syntax, you live in the syntax. Fine if you write Markdown all day. Not fine if you're just trying to clean up an AI's output. "Notion-likes" — beautiful, but your text lives in their database, behind their account, on their servers. The file is gone. I wanted the third option: a real desktop app that looks like a document, but the file on disk stays plain .md. Click to bold. Click to insert a table. Click to type an equation — actually type it, not write LaTeX. Cite from a .bib library and export to Word with a numbered bibliography. Plug in your own Claude/OpenAI/Gemini key for Tab-to-complete and pay your provider, not me. That's MDX. Built in Rust + Tauri so it's tiny and native on macOS, Windows and Linux. No account. No telemetry. No subscription — $15 once and it's yours. Thanks for taking a look 🧡 — Vincent
