The plugin focuses on three core jobs:
<ul>
<li>Answer with your own knowledge base: Use Retrieval-Augmented Generation (RAG) so the chatbot answers from your website content and uploaded documents.</li>
<li>Escalate to a human when needed: When AI is not enough, visitors can switch to Live Chat and your team can continue the conversation from the built-in Inbox.</li>

</ul>
Main features:

<li>Live Agent Handoff: Switch between AI and Live Chat using schedule rules, manual override, or user request.</li>
<li>WooCommerce Product Support: Search products, recommend items, and show product cards inside chat.</li>
<li>WooCommerce Cart Actions: Add to cart from chat, refresh cart summary, update quantities, or remove items.</li>
<li>WooCommerce Checkout Assist: Detect checkout requirements, collect required fields, show payment methods, and create an order from chat when your store supports it.</li>
<li>Order Lookup: Surface recent order information for logged-in or identified customers.</li>
<li>WooCommerce-Aware Agent Inbox: Support agents can see useful context such as contact info, last seen page, recently viewed pages, cart snapshot, and recent orders.</li>
<li>Personalized User Context: Logged-in WordPress/WooCommerce users can be recognized automatically for more relevant support.</li>
<li>Live Chat Uploads: Visitors can send images, documents, and voice messages during live chat with staff.</li>

<h4>Why “Swayam”?</h4>
Swayam (स्वयं)—an ancient Sanskrit word meaning “self.” Your content. Your knowledge. Autonomously intelligent.
Swayam AI Chatbot is a WordPress plugin that provides an intelligent chatbot powered by Retrieval-Augmented Generation (RAG) technology. It indexes your WordPress content and uses AI to answer visitor questions based on your actual posts, pages, and custom post types.
<h4>Features</h4>
<ul>
<li>RAG-Powered Q&A – Answers questions using your actual WordPress content as context</li>
<li>Automatic Content Indexing – Syncs posts, pages, and custom post types to a vector database</li>
<li>Auto-Sync on Publish – Automatically updates the index when content is published, updated, or deleted</li>
<li>Customizable Chat Interface – Use the shortcode or floating widget</li>
<li>Admin Dashboard – Easy configuration with connection testing</li>
<li>REST API – Programmatic access to the chatbot</li>
<li>Rate Limiting – Built-in protection against spam</li>
</ul>
<h4>Shortcode Usage</h4>
Embed the chatbot on any page or post:
<pre><code>[swayam_ai_chatbot]
</code></pre>
With custom attributes:
<pre><code>[swayam_ai_chatbot title="Ask about our products" placeholder="What would you like to know?"]
</code></pre>
