GitHub Flavored Markdown (GFM) is the dialect of Markdown that GitHub uses in README files, issues, and pull requests. It extends the original 2004 Markdown spec with extras that plain Markdown lacks: tables built from pipes and a divider row, task lists written as "- [ ]" and "- [x]" checkboxes, strikethrough with double tildes, and automatic linking of bare URLs. This editor renders full GFM, so the syntax you write previews the same way it will appear once committed to a GitHub repo. It also adds highlighted text with "==marks==", footnotes, definition lists, and GitHub-style alert callouts such as "> [!NOTE]". That means you can draft a README or issue here and trust the rendered result. Type or paste your Markdown above to see GFM rendered live as you write.

Markdown is whitespace- and symbol-sensitive, so small mistakes that look fine in raw text break once rendered. A table needs a header row, a divider row of dashes and pipes like "|---|---|", and a consistent pipe count on every line; drop a divider or misalign a pipe and the whole block falls back to plain text. Code blocks need matching triple-backtick fences — an unclosed fence swallows everything after it into one big code span. Lists break when indentation is uneven or a blank line splits them unexpectedly. A live side-by-side preview is the fastest way to spot these, because you see the failure the moment you type it rather than after committing a malformed README. Watch the right-hand panel update as you edit above and fix the divider, fence, or indentation until it renders cleanly.

Once your document renders the way you want, this editor gives you several export paths. You can copy the rendered HTML straight to your clipboard to paste into a CMS, an email template, or a web page, or download a styled HTML file that preserves the preview's formatting and theme. You can also copy or download the raw Markdown as a ".md" file to commit to a repo or keep as a backup. For a fixed-layout, shareable copy, use Print to PDF through your browser's print dialog, which captures the rendered preview rather than the raw source. Because conversion happens locally in your browser, none of your text is uploaded during export, so private specs and drafts stay on your device. Finish your document above, then pick the export format that matches where the content is headed.

This editor offers three layouts for different stages of writing. Split view shows the editor and the live preview side by side, so you watch formatting render as you type — ideal for catching mistakes while drafting. Source-only hides the preview for distraction-free writing when you already know the syntax and just want a clean canvas. Preview-only hides the raw Markdown and shows just the finished, rendered result, which is best for reading or proofreading the final output. In split view, scroll syncing keeps both panels aligned as you move through a long document, and you can toggle it off to scroll each panel independently. You can also switch among five preview themes — GitHub, Dark, Minimal, Academic, and Sepia — to match where the content will be published. Pick the layout above that fits whether you are drafting, focusing, or reviewing.

A live statistics panel updates as you type and counts more than just words. It tracks words, characters, sentences, paragraphs, and structural elements specific to Markdown — headings, links, images, code blocks, tables, and completed-versus-total task list items — so you can size up a document at a glance. Reading time is estimated at roughly 200 words per minute, the commonly cited average for adult silent reading, which makes it a quick gauge for a blog post or documentation page rather than an exact measurement; dense technical content with lots of code naturally reads slower. Because everything is computed in your browser, the stats refresh instantly even on long documents with no upload or delay. Start typing above and watch the word count, structure tallies, and reading-time estimate update in real time as your draft grows.
