Default per-page directive for AI agents

Every page served to AI agents now includes a default directive that tells agents how to navigate your documentation programmatically — pointing them to .md URLs, llms.txt, and llms-full.txt. The directive is automatically generated using your site's domain and basepath, so no configuration is needed.

For clean Markdown of any page, append .md to the page URL. For a complete documentation index, see https://docs.example.com/llms.txt. For full documentation content, see https://docs.example.com/llms-full.txt.

You can still override the default with a custom directive or disable it entirely.

Standalone search widget

Embed Ask Fern's AI-powered search on any React site using the @fern-api/search-widget package. The widget renders a button that opens a search modal connected to your documentation content. It requires React 19; all other dependencies are bundled.
