Personal Shopper Chatbot for WooCommerce with RAG using Google Drive and openAI

Last edited 9 days ago

This workflow combines OpenAI, Retrieval-Augmented Generation (RAG), and WooCommerce to create an intelligent personal shopping assistant. It handles two scenarios:

  1. Product Search: Extracts user intent (keywords, price ranges, SKUs) and fetches matching products from WooCommerce.
  2. General Inquiries: Answers store-related questions (e.g., opening hours, policies) using RAG and documents stored in Google Drive.

How It Works

1. Chat Interaction & Intent Detection

  • Chat Trigger:
    • Starts when a user sends a message ("When chat message received").
  • Information Extractor:
    • Uses OpenAI to analyze the message and determine if the user is searching for a product or asking a general question.
    • Extracts:
      • search (true/false).
      • keyword, priceRange, SKU, category (if product-related).
    • Example:
      {  
        "search": true,  
        "keyword": "red handbags",  
        "priceRange": { "min": 50, "max": 100 },  
        "SKU": "BAG123",  
        "category": "women's accessories"  
      }  
      

2. Product Search (WooCommerce Integration)

  • AI Agent:
    • If search: true, routes the request to the personal_shopper tool.
    • WooCommerce Node:
      • Queries the WooCommerce store using extracted parameters (keyword, priceRange, SKU).
      • Filters products in stock (stockStatus: "instock").
      • Returns matching products (e.g., "red handbags under €100").

3. General Inquiries (RAG System)

  • RAG Tool:
    • If search: false, uses the Qdrant Vector Store to retrieve store information from documents.
    • Google Drive Integration:
      • Documents (e.g., store policies, FAQs) are stored in Google Drive.
      • Downloaded, split into chunks, and embedded into Qdrant for semantic search.
    • OpenAI Chat Model: Generates answers based on retrieved documents (e.g., "Our store opens at 9 AM").

Set Up Steps

1. Configure the RAG System

  • Google Drive Setup:
    • Upload store documents .
    • Update the Google Drive2 node with your folder ID.
  • Qdrant Vector Database:
    • Clean the collection (update Qdrant Vector Store node with your URL).
    • Use Embeddings OpenAI to convert documents into vectors.

2. Configure OpenAI & WooCommerce

  • OpenAI Credentials:
    • Add your API key to all OpenAI nodes (OpenAI Chat Model, Embeddings OpenAI, etc.).
  • WooCommerce Integration:
    • Connect your WooCommerce store (credentials in the personal_shopper node).
    • Ensure product data is synced and accessible.

3. Customize the AI Agent

  • Intent Detection:
    • Modify the Information Extractor’s system prompt to align with your store’s terminology.
  • RAG Responses:
    • Update the tool description to reflect your store’s documents.
