ai_rag_search_summary

Introduction

AI RAG Search Summary turns your Search API vector search into an intelligent Q&A system. Users ask questions in plain language and get an AI-generated summary answer along with the actual source documents used to verify information and explore deeper. No more scrolling through search results.

Choose how sources appear: use any Drupal view mode (teaser, full, custom) to render source nodes with your existing templates, or use the default JSON format. Style with CSS variables to match your theme.
