Works with Claude & Claude Code output

Open Claude's Markdown as a real document.

Claude is great at long-form: reports, specs, documentation, Artifacts — and it all comes out as Markdown. MDX opens those .md files, including the ones Claude Code drops into your repo, and lets you edit them visually, then export to Word or PDF.

Built for long documents

Claude writes multi-page reports, specs and documentation. MDX gives them real headings, an outline and a document feel — not a cramped chat bubble.

ii.

Claude Code files, readable

Plans, READMEs and design docs that Claude Code drops into your repo open as formatted documents you can actually review and edit — while git still sees plain Markdown.

iii.

Hand it off in Word

Export Claude's draft to .docx for a colleague or .pdf for sign-off, with formatting and any math intact.

From a Claude answer or Artifact to an editable doc

Save the Markdown. Copy the response, download the Artifact as Markdown, or open the .md file Claude Code created.
Open in MDX. Paste it in or double-click the .md file — it renders as a formatted document.
Refine and export. Edit by clicking, then save as .md or export to Word, PDF, or HTML.

Claude Markdown — questions

Can I edit a Claude Artifact after creating it?

Yes. Download the Artifact as Markdown and open it in MDX to edit it like a document, then re-export to .docx, PDF, or HTML.

Does MDX work with the Markdown files Claude Code writes into my project?

Yes. MDX opens any .md file on disk — plans, READMEs, design docs — and shows them formatted while keeping the file as plain Markdown that git continues to track.

Will Claude's equations render?

Yes. LaTeX-style math written as $$ … $$ renders as editable math via MathLive and exports correctly to Word, PDF, and HTML.

Is my document sent anywhere?

No. MDX is local-first with no account and no telemetry. Optional AI features use your own API key and go straight to the provider you choose.
