Smart FAQ Chatbot

Smart FAQ Chatbot provides an AI-powered conversational assistant that dynamically answers user questions using your site’s internal content. It supports filtering by content type, taxonomy term, and product type.

Automatically logs recent questions and answers for display below the input field.

Supports filtering by:

Product type (for Commerce sites)
