Basic installation
Add a Biel.ai AI assistant or AI search widget to any HTML site. This method uses CDN-hosted components — no build tools or package managers required.
Prerequisites
- A Biel.ai account.
- A project with indexed content.
Add the assistant widget
The <biel-button> component adds a floating chat button to your site.

-
Add the following inside the head section of your HTML:
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/biel-search/dist/biel-search/biel-search.css"><script type="module" src="https://cdn.jsdelivr.net/npm/biel-search/dist/biel-search/biel-search.esm.js"></script> -
Add the following just before the closing body tag:
<biel-button project="<YOUR_PROJECT_ID>"header-title="Biel.ai assistant"button-position="bottom-right"modal-position="bottom-right"button-style="dark">Ask AI</biel-button>Replace
<YOUR_PROJECT_ID>with your project's ID from the Biel.ai dashboard. -
Open the page in a browser to verify the assistant appears in the bottom-right corner.
Add the search widget
The <biel-search-button> component adds an AI-powered search bar instead of (or alongside) the assistant.

-
Add the following inside the head section of your HTML:
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/biel-search/dist/biel-search/biel-search.css"><script type="module" src="https://cdn.jsdelivr.net/npm/biel-search/dist/biel-search/biel-search.esm.js"></script> -
Add the following where you want the search button to appear:
<biel-search-button project="<YOUR_PROJECT_ID>" button-style="rounded">Search</biel-search-button>Replace
<YOUR_PROJECT_ID>with your project's ID from the Biel.ai dashboard. -
Open the page in a browser to verify the search widget works.
Select a widget version
The links above omit a version, which is equivalent to biel-search@latest. The browser loads the latest published npm release from jsDelivr. It can change without rebuilding your site, although CDN caching means a new release may not appear immediately.
To use a specific release, include the same version in both asset URLs:
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/biel-search/biel-search.css">
<script type="module" src="https://cdn.jsdelivr.net/npm/[email protected]/dist/biel-search/biel-search.esm.js"></script>
Replace 0.1.93 with your chosen release. Remove the version, or use @latest, to follow new releases again. See jsDelivr's versioning and caching documentation.
Next steps
- Customize the widget's appearance, behavior, and tone.
- Connect integrations like GitHub Actions, MCP, or Zapier.
