Voice AI Chatbot with ElevenLabs & InfraNodus GraphRAG Experts

This n8n workflow creates an advanced voice AI chatbot that leverages ElevenLabs for seamless voice interactions and InfraNodus GraphRAG knowledge graphs as specialized 'experts'. The AI agent in n8n orchestrates the process, deciding which knowledge base to query based on the user's voice prompt received via webhook. This setup enables holistic knowledge retrieval, capturing relations between data chunks for more accurate and context-aware answers without complex vector store configurations.

Key benefits include quick setup and updates—no need for intricate data import pipelines—reusability across workflows, and superior response quality from graph-based RAG over traditional methods. It's ideal for embedding on websites or API use, perfect for customer support, news aggregation, or personalized advisory services.

The flow works as follows: User speaks via ElevenLabs interface; prompt hits n8n webhook; AI agent selects and queries relevant InfraNodus graph; response returns to webhook for ElevenLabs to vocalize. Use cases span lifestyle apps like news briefings, educational tutors, or virtual experts in any domain with pre-built knowledge graphs.
