Markdown Preview

Write on the left, see it on the right. Any raw HTML in the source is escaped, so pasting someone else's Markdown cannot inject a script.

Notes

Everything is escaped first and only known markers are restored, so no <script> can get through.
Supports a practical subset: headings, bold/italic, inline code, fenced code, lists, tables, quotes, links, images, strikethrough.
Footnotes, math and mermaid are not supported.
