FAQs
Which Markdown flavour?
GitHub-Flavoured Markdown (GFM) via remark-gfm. CommonMark base plus tables, strikethrough, task lists and autolinks.
How is this different from the Markdown tool?
Same engine, different framing. The /tools page is task-focused (convert MD to HTML and copy). This playground is exploration-focused - tweak markdown, see preview, learn syntax.
Does it support raw HTML in Markdown?
Yes - <kbd>, <sub>, <video> all pass through. The preview renders them as HTML. We don't sanitise (your own content, your own page).
Can I export the rendered HTML?
Use the Copy code button on the output, or Download to grab a .md of your source.
