How to Add an AI Chatbot to WordPress
An AI chatbot answers visitor questions 24/7, reduces support load, and increases conversion by keeping visitors engaged when a human is not available.
Types of WordPress Chatbots
- Rule-based chatbots: Follow decision trees. Predictable but limited to scripted responses.
- AI chatbots: Use large language models to understand natural language and generate contextual responses.
- Hybrid chatbots: Rule-based flows with AI fallback for unexpected questions.

Training Your Chatbot on Site Content
Most AI chatbots can crawl your site or accept uploaded documents to build a knowledge base. The more specific and structured your source content, the better your bot answers. Maintain a dedicated FAQ page that your chatbot uses as its primary reference.
Implementation Tips
- Start with FAQ and pricing questions — highest frequency, easiest to answer accurately
- Set clear handoff to human support for complex issues
- Review chatbot conversations weekly to identify gaps in your knowledge base
- Test the chatbot on mobile — most chat interactions happen on phones
