Markdown Editor With Better Complex Math Equation Support .

This is a little Markdown editor Try here. It's designed to handle a bunch of cool stuff, making it easy to write and preview your documents.

Unlike other Markdown preview apps, this one can render almost all LLM-generated output including math formulas, equations, and tables - directly in Markdown.

What Can It Do? ✨

Quick rundown of the features:

• Live Markdown Preview: As you type Markdown on the left, you'll see it rendered as HTML on the right, almost instantly!
• Switchable Markdown Engines: You can choose between two popular Markdown parsers:
  • markdown-it: Generally great for features like footnotes and follows CommonMark closely.
  • marked: Another fast and reliable option.
• Awesome Math Support: Write your math equations using LaTeX syntax!
  • Supports inline math like $E=mc^2$ and display math like $$ ... $$ or \[ ... \].
  • You can switch between MathJax and KaTeX to see which renders your math best.
• Code Syntax Highlighting: Paste your code blocks (like Python, JavaScript, CSS, etc.), and they'll get nicely colored using highlight.js. Just make sure to specify the language after the first three backticks (e.g., ```python).
• Mermaid Diagrams: Create flowcharts, sequence diagrams, and more directly in your Markdown using Mermaid syntax (just use a ```mermaid code block).
• Footnotes: Easily add footnotes[^1] using the standard Markdown syntax (requires markdown-it engine).
• Download Your Work:
  • Save as PDF: Get a PDF version of your rendered preview.
  • Save as MD: Download the raw Markdown text you typed.
  • Save as TXT: Get a plain text file.
• Custom Preview Styles: Want the preview to look a bit different? Hit the "Custom CSS" button and add your own CSS rules to tweak the appearance.

How to Run It Locally 🚀

Getting this running on your own machine is super simple because it's just HTML, CSS, and JavaScript.

1. Download the Files: Make sure you have all the files (index.html, style.css, script.js, and this README.md) in a folder on your computer.
2. Open the HTML File: Just double-click the index.html file. Your web browser (like Chrome, Firefox, Edge, etc.) will open it right up.
3. That's It! You should see the editor ready to go.

Important Note: This editor relies on several external libraries (like markdown-it, MathJax, KaTeX, highlight.js, Mermaid, etc.) that are loaded from the internet (CDNs). This means you'll need an active internet connection for all the features to work correctly when you run index.html locally.
