Unmarkdown™ for Chrome
Convert AI markdown to beautifully formatted text in one click. Right where you already work.
How it works
AI outputs markdown
ChatGPT, Claude, or Gemini responds with markdown in a code block. The extension detects it automatically.
Purple button appears
A small button appears below the code block. No need to select text, open menus, or copy anything manually.
One click, formatted
Click the button and the markdown is converted and copied to your clipboard, formatted for your chosen destination. Paste it and it just works.
Works where AI lives
The extension scans code blocks on AI platforms for raw markdown syntax. When it finds markdown, the convert button appears automatically.

The popup: paste, preview, copy
Click the extension icon in your browser toolbar to open the popup. It works with any markdown, not just AI output.
Paste or type markdown on the left side. A live preview renders on the right. Pick your destination from the grid, choose a template, and click "Copy for [destination]" to copy the formatted output to your clipboard.
You can also download as Word (.doc) or HTML. The theme toggle lets you switch the preview between light and dark mode. Clipboard copy always uses light theme so pasted content looks right on white backgrounds.
Privacy: everything stays local
All conversion happens on your machine. The extension does not send your content to any server, does not collect analytics, and does not phone home. There is no account, no sign-in, and no tracking.
The extension requests minimal permissions: it reads code blocks on AI platforms to detect markdown. It does not access your browsing history, cookies, or any data outside of the pages it runs on.
Free, forever
The Chrome Extension is completely free. No trial, no freemium upsell, no usage limits. Convert as many documents as you want, as often as you want.
