🧠 RAG AI Medical Agent – n8n Workflow 👥 Who’s it for This workflow is perfect for: Healthcare ecommerce businesses** that want to automate product recommendations. Founders or developers** building an AI assistant using retrieval-augmented generation (RAG) with product data. Anyone** wanting to combine OpenAI, Qdrant vector search, and Google Sheets to power intelligent medical queries. ⚙️ How it works / What it does This RAG-based workflow allows users to ask medical questions related to hair or scalp issues (e.g., hair loss, thinning). It: Retrieves product info from a Google Sheet. Converts product data into text embeddings using OpenAI. Stores those embeddings in a Qdrant vector database. On chat message trigger, performs a vector similarity search to match user symptoms with relevant products.

Add your OpenAI API key in the embedding nodes. Add your Qdrant credentials in the vector store nodes. Step 3: 🧠 Populate the Vector DB Click “Execute workflow” manually. This pulls data from the Google Sheet. Each row is: Formatted properly into a vector-friendly string. Converted into an embedding using OpenAI. Stored into Qdrant. Step 4: 💬 Enable Chat Interface Use the ChatTrigger to receive user queries. The agent searches Qdrant for relevant vectors. Replies with product suggestions via LangChain's LLM agent. 📋 Requirements 🧠 n8n 📄 A Google Sheet with product data. 🔐 Google Sheets OAuth2 credentials. 🧠 OpenAI API key (for embeddings + chat LLM). 🗃️ Qdrant Vector DB instance (Cloud or self-hosted). 🧩 How to customize it 🔄 Change the data structure Update the "Set Data Properly in vector database" node to modify what fields are embedded. Example: --- Product: {{ $json['Product Name '] }} Use-case: {{ $json['Symptoms Involved'] }} Link: {{ $json['ForeverBetty Product Page Link '] }}. An n8n automation workflow template by Zain Ali.
