Start typing — the preview updates live.
How to use the Markdown previewer
- Type or paste Markdown on the left.
- The formatted result renders live on the right as you type.
- Use it to proofread a README, issue or comment before you post it.
Rendering happens entirely in your browser, so private notes and drafts are never uploaded.
Markdown in 30 seconds
Markdown is a plain-text way to write formatted documents. A few marks do most of the work:
- # Heading, ## Subheading for titles.
- **bold** and *italic* for emphasis.
- - item for bullet lists, 1. item for numbered lists.
- [text](https://example.com) for links, and backticks for code.
Where you'll use it
Markdown is the standard for README files, GitHub and GitLab issues and pull requests, documentation sites, chat tools like Slack and Discord, and many note-taking apps. Previewing first means you catch a broken list or an unclosed link before it ships in front of a reader.
Where you'd use this
Writing Markdown somewhere that will not show you the result: a GitHub issue or pull request description, a README, a static-site post, a documentation page in a repo you have not built locally.
For example: You are drafting a bug report with a nested list, a table of reproduction steps and a fenced code block. The preview shows the table needs a blank line before it to render at all — better to find that now than after posting to a public issue tracker.
Frequently asked questions
What Markdown syntax does it support?
Standard Markdown — headings, bold and italic, lists, links, images, blockquotes, code blocks and tables — rendered live as you type.
Can I use it to draft a README or GitHub comment?
Yes. It is handy for previewing READMEs, GitHub issues or any Markdown before you publish, so you catch formatting mistakes first.
Is my Markdown uploaded?
No. Rendering happens in your browser; nothing you write is sent to a server.
