Drop two files into your project. No LLM calls, no API keys, no backend. Pattern-based intelligence that works instantly and costs nothing.
Answers questions instantly from your knowledge base. No LLM latency, no hallucinations, no API cost — ever.
Conversations persist across reloads via localStorage. Users can browse, resume, and delete past chats — just like ChatGPT.
Change name, color, avatar, and copy with a single config object. One line per property. Works on any color palette.
The widget reads the current URL and opens with a tailored message — pricing, about, contact, or custom pages.
After a configurable delay, the widget subtly bounces to invite interaction — capturing attention without pop-ups.
After N messages, offer a name/email form. One line to hook it into your CRM, Netlify form, or Make.com webhook.
Full-width bottom sheet on mobile. Premium floating panel on desktop. Spring-eased animations feel native everywhere.
When you need true NLU, replace one function with a fetch() call to Gemini or GPT. All the UI stays identical.
Drop widget.js and widget.css into your project. No npm install, no build step, no dependencies.
Set window.AgenticChatConfig with your name, color, and avatar. Fill window.KB with your answers.
One <link> in your <head> and one <script> before </body>. The widget auto-initialises instantly.
<!-- In <head> -->
<link rel="stylesheet" href="widget.css">
<!-- Before </body> -->
<script>
window.AgenticChatConfig = {
name: 'Aria', // Widget name
brand: '#c9a84c', // Brand color
avatar: 'avatar.png' // Avatar image
};
window.KB = {
pricing: {
patterns: [/price|cost|fee/i],
responses: ['Our plans start at...'],
chips: ['Get a quote', 'See plans']
},
// ...add more intents
};
</script>
