DocumenterCopyButton.jl

A Documenter.jl plugin that adds floating "Copy as Markdown" and "Open in AI" buttons to opted-in documentation pages.

Quick Start

Add DocumenterCopyButton to your docs environment, then pass the plugin to makedocs:

using Documenter
using DocumenterCopyButton

makedocs(;
    plugins = [CopyButton()],
    # ...
)

Then add a @copybutton block to any page you want to enable:

```@copybutton
```

The page will show floating buttons in the bottom-right corner:

• Copy — copies the page's markdown source to the clipboard
• AI — dropdown to open the page in Claude, ChatGPT, Perplexity, and more

Features

• Works offline and with file:// URLs — markdown is embedded directly in the HTML
• Bulma-native theming — inherits Documenter's active theme (light, dark, catppuccin, etc.)
• Custom source files — point to a Literate.jl script or any other file
• Configurable AI providers and prompt prefix

Usage with Literate.jl

In Literate.jl source files, add the block as a comment:

# ```@copybutton
# literate/tutorials/my_tutorial.jl
# ```

# # My Tutorial
using MyPackage
# ...
