Write Markdown with Instant Visual Feedback

Markdown is the de facto standard for technical writing on the web. GitHub README files, developer documentation, blog posts, release notes, and knowledge bases all rely on it. The syntax is intentionally minimal — you focus on content while Markdown handles the formatting.

Our online editor gives you a side-by-side writing and preview experience. The left pane is your editor, and the right pane renders the formatted output in real time. Every heading, list, link, image, table, and code block appears exactly as it will look when published. There is no need to toggle between editing and previewing or to install any software.

The editor supports GitHub Flavored Markdown, which extends standard Markdown with practical features like tables, task lists (- [x] Done), strikethrough (~~text~~), and fenced code blocks with language-specific syntax highlighting. If you write for GitHub, this editor matches the rendering you will see on the platform.

Markdown Syntax Quick Reference

Headings use hash symbols: # H1, ## H2, ### H3, and so on through H6. Use headings to structure your document and create a scannable hierarchy.

Emphasis is straightforward: *italic* for italic, **bold** for bold, and ***bold italic*** for both. Strikethrough uses double tildes: ~~deleted~~.

Lists begin with - or * for unordered items and 1. for ordered items. Indent with two spaces for nested lists. Task lists use - [ ] for unchecked items and - [x] for checked ones.

Links follow the pattern [text](url) and images use ![alt text](url). Reference-style links keep your source readable for long documents.

Code is marked with single backticks for inline code and triple backticks for code blocks. Add a language name after the opening triple backtick for syntax highlighting.

Tables use pipes and hyphens to define columns and alignment. GFM makes creating structured data tables straightforward without needing HTML.

Common Use Cases for an Online Markdown Editor

Drafting GitHub documentation is the primary use case. README files, CONTRIBUTING guides, changelogs, and wiki pages all use Markdown. Previewing them in an environment that matches GitHub’s rendering ensures your formatting is correct before you commit.

Writing blog posts for static site generators like Astro, Next.js, Hugo, and Jekyll is seamless. These frameworks consume Markdown files directly, so you can draft, preview, and fine-tune your post here, then drop the file into your project.

Composing emails and messages that need formatting benefits from Markdown as well. Write your content in Markdown, copy the rendered HTML, and paste it into email clients or platforms that accept rich text. This produces cleaner markup than most visual editors.

Taking developer notes in Markdown keeps your notes portable and future-proof. Unlike proprietary note app formats, Markdown is plain text that any editor can open, and its formatting survives decades of technology changes.

Why Markdown Beats Rich Text Editors

Rich text editors like Google Docs and Microsoft Word store formatting in proprietary binary or XML structures. Copying content from these editors into a CMS, email, or web page often introduces invisible markup that breaks layouts or creates inconsistent styling.

Markdown solves this by making formatting explicit and human-readable. A ## heading is always a second-level heading. A **bold** word is always bold. There is no hidden formatting to debug, no clipboard mangling, and no version compatibility issues. The source file is plain text that Git can diff, merge, and track with full fidelity — making Markdown the natural choice for any content that lives alongside code.
