Frequently asked questions

How do I add an AI chatbot to my website or web app?

Create a free ZFusionAI account, build an agent, enable its web widget and paste the one-line script tag into your site. The chat bubble appears immediately and answers visitors with your agent.

Is the website AI chat widget free?

The free trial includes 1,000 messages shared across the web widget, AI agent API and WhatsApp. Each widget reply uses one message.

Does the widget slow down my website?

No. widget.js is a small dependency-free script that loads asynchronously and renders inside a Shadow DOM, so it doesn't affect your page's styles or Core Web Vitals.

Can ZFusionAI also build my full web application?

Yes. ZFusionAI is a Dubai-based full-stack development company that builds custom web applications with React, TypeScript, Node.js and PostgreSQL, and can integrate AI agents directly into them.
