About the Markdown Preview
Type Markdown in the left pane and watch it render on the right in real time — no save button, no page refresh, no guesswork. Headings, bold and italics, links, images, ordered and unordered lists, blockquotes, tables, code blocks and horizontal rules all display exactly as they'll appear, so you can polish a README, blog post or forum reply before publishing it anywhere.
It's a handy scratchpad when your editor lacks a preview, when you're learning Markdown syntax, or when you want to sanity-check formatting destined for GitHub, Reddit, Discord or a static-site generator. Raw HTML in your input is escaped rather than executed, so pasted content can't inject scripts or styling into the preview. Everything renders locally in your browser, which means your drafts never leave your device.

Frequently asked questions
What Markdown syntax is supported?
The common core: headings with #, bold and italic emphasis, links and images, ordered and unordered lists, blockquotes, inline code and fenced code blocks, tables and horizontal rules. If you write for GitHub or most blogging platforms, everything you use day to day will render as expected.
Why isn't my raw HTML rendering?
By design, HTML tags in your Markdown are escaped and shown as plain text rather than executed. That prevents pasted content from running scripts or breaking the page layout. If your target platform allows inline HTML, it will still work there — this preview simply plays it safe.
Can I use this to write a GitHub README?
Yes — it's a fast way to draft one. The core syntax matches what GitHub renders, including tables and fenced code blocks. GitHub layers a few extras on top, such as task-list checkboxes and automatic issue links, so give the finished README one final glance after pushing.
Is my text saved or uploaded anywhere?
No. Rendering happens entirely in your browser with JavaScript, so your writing is never transmitted to or stored on a server. If you close or reload the tab the draft is gone, so copy your work somewhere permanent when you finish a writing session.
Why do my line breaks disappear in the preview?
Standard Markdown treats a single newline as a space and requires a blank line to start a new paragraph. To force a line break inside a paragraph, end the line with two spaces or a backslash. This trips up nearly everyone at first — it's Markdown behaving normally, not a bug.
