ShopAssist AI — RAG-Based Voice Assistant for Shopify
An Alexa-like voice assistant connected directly to a Shopify store — letting customers ask about products, orders, pricing, and shipping policies out loud and receive accurate, real-time, store-specific spoken answers using Retrieval Augmented Generation.

01 / Project Overview
What We Built & Why
Most ecommerce support is built around typing — chatbots, FAQ pages, search bars. But a growing segment of shoppers expect to speak their questions, just as they would ask a shop assistant in person. Traditional voice assistants like Alexa give generic answers; they know nothing about a specific store's inventory, pricing, or policies.
We built ShopAssist AI — a RAG-powered voice assistant built with Python, FastAPI, and OpenAI — that integrates directly with a Shopify store and speaks back accurate, context-aware answers using real-time product, order, and policy data rather than static pre-written responses.
Core problem solved: Generic voice assistants can't answer "Do you have the midnight blue hoodie in XL?" or "Where's my order?" ShopAssist AI can — because it's connected to the live Shopify store and uses RAG to ground every spoken answer in actual store data.
Voice-First Interface
Speak naturally — the assistant transcribes, understands, and responds with a natural voice reply.
RAG Engine
Every answer grounded in actual store data — products, orders, and policies retrieved and cited.
Shopify Integration
Live connection to Shopify — inventory, pricing, orders, and shipping fetched in real time.
Context-Aware
Remembers prior questions — follow-ups work naturally without repeating context.
02 / How It Works
The Voice AI Pipeline — Speak to Answer
From spoken question to voice response — the full RAG pipeline runs in real time, pulling live Shopify data and generating accurate, store-specific spoken answers.
Customer speaks a question — captured via the browser or device microphone.
Audio transcribed to text using OpenAI Whisper — accurate, real-time conversion that handles accents and product-specific vocabulary.
FastAPI + OpenAI classify the intent — product query, order tracking, pricing, or policy — and route to the correct retrieval pipeline.
Live Shopify API call retrieves the relevant data — product variants, order status, current pricing, or shipping policy.
Vector database queried for the most relevant store knowledge — product descriptions, policy documents, FAQs — to ground the AI response.
OpenAI generates a concise, natural answer using the retrieved store data — phrased for spoken delivery, accurate and grounded in real facts.
Answer converted to natural-sounding speech and played back to the customer — delivering the full Alexa-like conversational voice experience.
Conversation history maintained — follow-up questions like "what about in navy?" understood without re-stating context from scratch.
