MDX Reader
Paste or upload MDX — the Markdown-plus-JSX format AI coding agents write for docs, blogs, and changelogs — and read it the way a human reads: frontmatter pulled into a table, JSX components unwrapped to their text (or replaced with a plain[Component]marker), and a clean plain-text version with zero markup left in it.

Why MDX is hard to read raw
AI agents — Claude Code, Cursor, and doc-generation pipelines alike — write MDX because it lets prose sit next to interactive components: <Callout>, <Tabs>, <CodeGroup>, YAML frontmatter, and {expr} interpolation. That is exactly the syntax a renderer needs and a human reading raw source does not.
What this tool does — and doesn't
It parses the MDX syntax tree, pulls out frontmatter, unwraps JSX components to the text inside them (or a short placeholder when they hold none), and neutralizes {expr}blocks it can't evaluate. It never executes any component or expression — this is a text transform, not an MDX renderer, so it's safe to run on MDX from anywhere.
