What Unmarked does not render yet

Footnotes ([^1]) and math/LaTeX ($…$) aren't rendered yet: they show as the plain text you wrote. Both are on the roadmap. Remote https:// images show their alt text, while images stored next to your file render normally.

Unmarked renders the Markdown you write every day: headings, bold and italic, lists and task lists, blockquotes, inline and fenced code, links, tables, horizontal rules, and YAML frontmatter as a properties panel. The full list is here. Two things stay as plain text for now, and one never loads by design.

Footnotes and math show as plain text

If a footnote looks broken, this is what's happening: the [^1] marker and its matching [^1]: definition stay in the document exactly as you typed them. No superscript, no jump to the note. Math is the same story: $E = mc^2$ shows as the literal source instead of a typeset equation.

Everything around them renders normally. A document with one footnote and a page of standard Markdown formats correctly everywhere except that footnote.

Nothing is dropped or rewritten. Your file keeps the original markup, so the day footnote and math rendering ship, the same document renders correctly with no change on your part.

Remote images show alt text on purpose

Unmarked has no network access, so an image that lives on the web can't be fetched. Where the picture would sit, you see its alt text. An image stored next to your file renders normally in every mode and export.

The full explanation and the quick fix live on Why remote images show as alt text. The reason the app has no network access in the first place is the privacy design, covered in How Unmarked keeps your files private.
