Turn any website into an AI support chatbot with OpenAI and Pinecone

Complete AI support system using website data (RAG pipeline)

This template provides a full end-to-end Retrieval-Augmented Generation (RAG) system using n8n. It includes two connected workflows:

A data ingestion pipeline that crawls a website and stores its content in a vector database. A customer support chatbot that retrieves this knowledge and answers user queries in real time.

Together, these workflows allow you to turn any public website into an intelligent AI-powered support assistant grounded in real business data.

Use cases

AI customer support chatbot for your website
Internal company knowledge assistant
Product FAQ automation
Helpdesk or IT support bot
AI receptionist for services
Semantic search over company content

How it works

Ingestion workflow Discover all URLs from a website sitemap. Filter and normalize the URLs. Fetch each page and extract readable text. Clean HTML into plain text. Split text into overlapping chunks. Generate embeddings using OpenAI. Store vectors in Pinecone with metadata.

Chatbot workflow A user sends a message via chat webhook. The agent queries Pinecone for relevant knowledge. Retrieved content is passed to OpenAI. OpenAI generates a grounded response. Short-term memory maintains conversation context.

How to use

Step 1 – Run ingestion Set your target website URL. Add Firecrawl, OpenAI, and Pinecone credentials. Create a Pinecone index. Execute the ingestion workflow. Wait until all pages are indexed.

Step 2 – Run chatbot Deploy the chatbot workflow. Set the same Pinecone index and namespace. Copy the chat webhook URL. Connect it to a website, chat widget, or WhatsApp bot. Start chatting with your AI assistant.

Requirements

Firecrawl account
OpenAI API key
Pinecone account and index
Public website to crawl
Optional: frontend chat interface

Good to know

The chatbot never answers from memory for business data. All company knowledge comes from Pinecone. If Pinecone returns nothing, the bot fails safely. HTML cleaning is basic and can be replaced with: Mozilla Readability
Jina Reader
Unstructured
Chunk size and overlap affect retrieval quality. Pinecone can be replaced with: Qdrant
Weaviate
Supabase Vector
Chroma

Customising this workflow

You can extend this system by: Adding PDF or document loaders Scheduling ingestion daily or weekly Connecting CRM or ticketing systems Adding appointment booking tools Switching to local or open-source models Adding multilingual support Storing raw content in a database Adding feedback or logging

Architecture overview

This template follows a modern AI system design:

Website → Ingestion → Embeddings → Pinecone → Retrieval → OpenAI → User

It separates: Data preparation (offline) Knowledge storage Runtime inference

This makes the system scalable, maintainable, and safe for production use.
