  • Taking formatted notes
  • Writing project proposals
  • Creating formatted emails

  • Bold: Wrap text with **double asterisks**
  • Italic: Wrap text with *single asterisks*
  • Links: Use [text](url) format
  • Images: Use ![alt text](image-url) format
  • Lists: Use - or * for bullets, 1. 2. 3. for numbered
  • Code: Use backticks for inline code, triple backticks for blocks
  • Quotes: Start lines with > for blockquotes

GitHub Flavored Markdown

This editor supports GitHub Flavored Markdown (GFM), which includes features like tables, task lists (checkboxes), strikethrough text using ~~tilde~~, and automatic linking of URLs. These extensions make Markdown more powerful for technical writing and project documentation.

Pro tips

Tips & best practices

Use keyboard shortcuts

Most Markdown syntax is faster to type than clicking buttons. Learn the common patterns like ** for bold and ## for headers.

Preview as you write

Keep the preview panel visible to catch formatting errors immediately instead of fixing them later.

Start with headers

Structure your document with clear headers before filling in content. This creates a logical outline.

Save frequently

Download your work regularly to avoid losing content. Browser data is not permanent.

Use consistent spacing

Add blank lines between paragraphs and sections for better readability in both source and preview.

Built for trust

Privacy & security

This Markdown editor runs entirely in your web browser. Your content is never uploaded to any server, stored in any database, or transmitted anywhere. It's 100% private and secure.
