Add a "Copy as Markdown" button to any website. One script tag.
Lets your readers copy page content as clean Markdown for AI tools (ChatGPT, Claude, Gemini, etc.) with a single click. Shows approximate token count.
Add before </body>:
<script src="https://zcag.github.io/copymd/copymd.js" defer></script>A floating button appears. Click it → page content is converted to Markdown → copied to clipboard.
- Extracts main content (skips nav, sidebar, footer, ads)
- Converts headings, lists, tables, code blocks, images, links to Markdown
- Adds page title and source URL as header
- Shows approximate token count on copy
- Works on any page — blogs, docs, knowledge bases, tutorials
Customize with data- attributes:
<script src="https://zcag.github.io/copymd/copymd.js"
data-position="bottom-left"
data-theme="light"
data-label="Copy for AI"
defer></script>| Attribute | Values | Default |
