Frequently Asked Questions
What Markdown flavor?
We use marked.js which implements CommonMark + GitHub Flavored Markdown (tables, task lists, strikethrough). Compatible with GitHub, Discord, Reddit.
Can I paste Markdown from GitHub?
Yes, almost any Markdown works. GFM features (tables, code blocks with syntax, task lists) render correctly.
Is the content saved?
No. Everything runs in your browser. Close the tab = content is gone. For autosaving to localStorage, tell us.
Can I use HTML in Markdown?
Yes — Markdown allows raw HTML. But for security, we sanitize common XSS vectors (no
<script> tags execute).Does it support LaTeX/math?
Not in the current version. For math formulas, use KaTeX or MathJax separately and paste rendered output.
Can I import a .md file?
Click "Open file" to load any .md file from your device. The content populates the editor.
