A live preview for what you are writing
Markdown is the shared language of writing online: GitHub READMEs, Reddit posts, Discord, every static site generator. Writing it blind is guesswork, since you cannot tell whether your asterisks made a list or a bold word until it renders. The tool puts an editor and a live preview side by side, parsed with GitHub Flavored Markdown so the output matches what GitHub shows.
What GitHub Flavored Markdown adds
On top of plain CommonMark, GFM brings the features people reach for most:
- Tables, so rows and columns render without hand-written HTML.
- Task lists with the checkbox syntax, and strikethrough with double tildes.
- Fenced code blocks, rendered in monospace with indentation preserved.
- Autolinks, so a bare URL becomes a link without bracket syntax.
The parser is the marked library, which tracks GFM semantics closely.
Preview questions
- Which markdown dialect does it follow?
- GitHub Flavored Markdown, the most common dialect online. Its main additions over CommonMark are tables, task lists, strikethrough, and autolinks.
- Can I style the preview with my own CSS?
- Not in place; the preview uses the site's typography. Copy the rendered HTML out and apply your own CSS in a separate page for a custom look.
- Can I paste an image and have it show?
- Not yet, because a markdown image needs a URL and a pasted binary would have to be uploaded first. Save the image and reference it by path.
- Why did my custom HTML get stripped?
- DOMPurify removes anything that could run a script. Most non-script HTML like divs and spans survives. If a specific element you need disappears, reach out through the contact page with a minimal example.
