How to Add a Free AI Assistant to Your Website

Get your Nexus API Key

Sign in to the Nexus Dashboard. In the Nexus Keys tab, click "New Key", give it a name (e.g., "Production Website"), and copy the generated key.

Store your Groq API Key

In the Dashboard, navigate to the Settings tab. Paste your Groq API key into the Groq Configuration section and click "Save Changes". Your key is securely encrypted and never exposed to the browser.

Whitelist your Domain

In the Dashboard, go to the Domains tab. Add your website domain (e.g., example.com). Only whitelisted domains can use your Nexus API key.

Add the Script Tag

Paste the following code into your HTML, preferably just before the closing </body> tag.

<script>
window.NexusConfig = {
  apiKey: 'YOUR_NEXUS_API_KEY',
  model: 'meta-llama/llama-4-scout-17b-16e-instruct',
  botName: 'Nexus AI',
  greeting: '👋 Hello! How can I assist you today?'
};
</script>

<script defer src="https://cdn.jsdelivr.net/npm/nexus-web-assistant@3.0.0/dist/nexus-assistant.min.js"></script>

That's it! Your website now has an AI assistant that understands its content. Users can ask questions and get instant, context-aware answers.
