Chatbot with ChatGPT Wordpress

SmartSearchWP transforms your WordPress website into an intelligent AI-powered assistant. Instead of adding a basic chatbot widget, SmartSearchWP builds a structured semantic intelligence layer on top of your content — allowing visitors to ask questions and receive accurate, contextual answers based on your own data. Whether you run an eCommerce store, corporate site, blog, or documentation platform, SmartSearchWP improves engagement, reduces support workload, and enhances content discovery. Why SmartSearchWP is different Many AI chatbot plugins simply connect your site to OpenAI. SmartSearchWP is built differently.

• AI-powered semantic search engine
• Structured contextual content retrieval using embeddings
• Modular architecture with dedicated addons
• Advanced usage and access control
• Full prompt customization
• WooCommerce and PDF integration

It is not just an AI chatbot — it is a structured intelligence layer for WordPress. Built for Professionals SmartSearchWP is designed for developers, agencies, and serious WordPress site owners who need performance, control, and scalability — not just a basic AI widget. Core Features AI Chatbot Integration Connect your website to OpenAI's ChatGPT models to provide dynamic, contextual answers based on your own content. Semantic Search Engine Improve content discovery with AI-driven semantic search instead of simple keyword matching. Contextual Content Indexing Index posts, pages, custom post types, and structured data to deliver accurate AI responses. Modular Architecture Extend functionality through dedicated addons without bloating your core installation. Advanced Control System Restrict AI usage by role, page, device, schedule, or quota to maintain full control over behavior and API costs. Prompt Customization Override and customize the system prompt to control tone, scope, and assistant behavior. WooCommerce Integration Turn your WooCommerce store into an intelligent AI-powered product assistant capable of answering customer questions contextually. PDF Integration Include PDF documents in your AI knowledge base to expand contextual understanding.
