FAQ
What is GitHub-Flavored Markdown (GFM)?
GFM is a Markdown dialect used on GitHub that adds tables, task lists, strikethrough, fenced code blocks with language hints, and autolinks to standard Markdown.
Is my Markdown document saved?
Your document is autosaved to your browser's localStorage every 500ms. Nothing is sent to any server. Clearing browser data will delete the saved content — use Export HTML or Download .md to keep a permanent copy.
How do I export my document as HTML?
Click the ⬇ HTML button in the toolbar. A self-contained .html file with inline CSS is downloaded to your device.
How do I export to PDF?
Click ⎙ PDF. Your browser's Print dialog opens. Choose "Save as PDF" as the destination. Print CSS hides UI chrome and shows only the rendered preview.
Does this editor support tables and task lists?
Yes. The editor supports GFM tables, task lists (- [x] / - [ ]), fenced code blocks, strikethrough, autolinks, blockquotes, and all standard Markdown.
