Create a travel support RAG chatbot with Google Drive, Pinecone and OpenAI

📊 Description This workflow helps travel, booking, and customer support businesses create an AI chatbot that answers customer questions from their own knowledge base. Instead of manually replying to repeated questions about bookings, cancellations, refunds, pricing, policies, or service details, the business can upload a knowledge document and let the chatbot respond through a webhook. Built for travel agencies, booking platforms, hotels, shortlets, service businesses, and automation builders who want to create a simple RAG chatbot using Google Drive, OpenAI, Pinecone, and n8n. What This Workflow Does 📄 Downloads a knowledge document from Google Drive ✂️ Splits the document into smaller chunks for better retrieval 🧠 Creates embeddings using OpenAI 📦 Stores the knowledge base inside a Pinecone vector index 💬 Receives customer questions through a webhook 🔎 Searches Pinecone for the most relevant information 🤖 Uses OpenAI to generate a short, helpful answer 📤 Returns the chatbot response back to the connected frontend, chatbot, or app Key Benefits ✅ Turns a simple document into a searchable AI knowledge base ✅ Helps answer repeated customer questions faster ✅ Uses RAG so responses are based on the uploaded business information ✅ Works with any frontend, chatbot, or app that can send a POST request ✅ Easy to customize for different travel, booking, or support businesses ✅ Separates knowledge indexing from live chatbot responses ✅ Includes a simple response formatting step before returning the answer How It Works SW1 — Knowledge Base Indexing The workflow starts with a manual trigger. It downloads a knowledge document from Google Drive, loads the document content, splits it into smaller text chunks, creates embeddings with OpenAI, and stores those chunks inside a Pinecone vector index. This section should be run first because the chatbot can only answer from information that has already been indexed into Pinecone. SW2 — Chatbot Question Answering The webhook receives a customer question from a frontend, chatbot, or app. The workflow sends the question into a retrieval QA chain, searches the Pinecone vector store for relevant context, and uses OpenAI to generate a short answer based on the retrieved information. The response is then cleaned by a Code node and returned through Respond to Webhook.
