👋 Note: Currently, the plugin’s backend interface and settings are fully in Spanish. We are actively working on translating it to English and other languages for future updates.
UZ AI Search transforms traditional WordPress search into a conversational experience using Artificial Intelligence.
Whether you need a conversational chatbot to provide customer support, or a smart informational search engine to help users explore your site’s content, UZ AI Search adapts completely to your needs. It allows your website visitors to find precise answers based exclusively on your own indexed content (posts, pages, products, and custom post types), utilizing OpenAI technology.
Key Features: 
* Versatile Use Cases: Configure the AI as a friendly customer service assistant or a strict knowledge base search. 
* Flexible Layout Options: Choose how the chat modal appears on your frontend (Centered popup, Fullscreen, or Left/Right Sidebars). 
* Advanced Semantic Search: Understands the actual intent behind your users’ questions. 
* Customizable Interface: Easily adjust themes (Light/Dark mode) to match your brand’s identity. 
* Selective Content Indexing: Control exactly which post types feed the AI’s knowledge (based on your active plan).
Important: The AI search assistant will respond in the language you specify in its prompt instructions. Please note that the default instructions are currently in Spanish. If you want the AI to answer in English (or any other language), you simply need to translate or adjust the instructions in the plugin’s settings.
