Build a voice AI chatbot with ElevenLabs and InfraNodus knowledge experts

Set Up ElevenLabs Voice Chat Agent using Graph RAG Knowledge Graphs as Experts

This workflow creates an AI voice chatbot agent that has access to several knowledge bases at the same time (used as "experts").

These knowledge bases are provided using the [InfraNodus GraphRAG](https://infranodus.com/use-case/ai-knowledge-graphs) using the knowledge graphs and providing high-quality responses without the need to set up complex RAG vector store workflows.

We use [ElevenLabs](https://elevenlabs.io) to set up a voice agent that can be embedded to any website or used via their API.

The advantages of using GraphRAG instead of the standard vector stores for knowledge are:

- Easy and quick to set up (no complex data import workflows needed) and to update with new knowledge - A knowledge graph has a holistic overview of your knowledge base - Better retrieval of relations between the document chunks = higher quality responses - Ability to reuse in other n8n workflows


How it works This template uses the n8n AI agent node as an orchestrating agent that decides which tool (knowledge graph) to use based on the user's prompt.
