AI chatbot for n8n docs with RAG, vector search, and…

This workflow builds an AI assistant that answers technical questions about n8n by retrieving information exclusively from the official documentation. Powered by RAG (Retrieval-Augmented Generation), Google Gemini embeddings, and an in-memory vector store, it enables developers and technical teams to get precise, up-to-date answers without AI hallucinations.

## Who it´s for
- n8n developers who need fast, accurate access to node and function documentation.
- Technical specialists learning n8n and requiring real-time guidance during implementation.
- DevOps teams automating processes and relying on error-free knowledge sources.
- Trainers and educators in low-code automation using RAG to build educational bots.

## What the automation does
- Scrapes and indexes text from the official n8n documentation using an HTTP Web Scraper.
- Splits content into chunks and generates vector embeddings via Google Gemini.
- Stores vectors in an in-memory vector database for fast retrieval.
- On user query via webhook, triggers a LangChain RAG agent to find relevant documentation snippets.
- Generates accurate responses with contextual awareness using conversation memory.
- Supports follow-up questions by preserving dialogue history.
