Celsian AI Chat Service
Once connected, the plugin communicates with Celsian AI servers:
<ul>
<li>Widget assets — JavaScript and CSS files are loaded from <code>chatbots.celsian.ai/widget/</code> to render the chat widget on your site. These files are required for the chatbot to function and cannot be bundled locally as they are part of the hosted service.</li>
<li>Chat API — When a visitor sends a message, it is sent to <code>converse.chatbots.celsian.ai/converse</code> along with the chatbot ID, the message text, and a randomly generated anonymous visitor ID. The AI response is returned and displayed in the widget.</li>
<li>Auto Setup (admin only) — If you use Auto Setup, the plugin opens <code>chatbots.celsian.ai</code> in a new tab with your site URL and site name to streamline the connection process.</li>
</ul>

<h4>How does the AI chatbot understand my website content?</h4>

<li>“Is the blue T-shirt in size M available?” – Looks up product stock and availability in WooCommerce</li>

</ul>
Other systems:
<ul>
<li>Support tickets – Show ticket status from helpdesk systems</li>
<li>Account info – Look up balances, memberships or custom data from any system</li>
</ul>
How to set it up:
<ol>
<li>Select the WooCommerce template (or another template for your system)</li>
<li>The chatbot asks customers to verify their identity (e.g. their order email)</li>
<li>Once verified, the chatbot can look up their orders, products and personal data</li>
</ol>
No programming knowledge required — the WooCommerce connector works out of the box.

</ol>
<h4>How does the spam protection work?</h4>
Built-in spam and abuse protection monitor usage patterns and prevent abusive or excessive requests. This helps protect your account from unexpected usage spikes and keeps your costs predictable on higher tiers.
