SmartCart
Inspiration
Online shopping often requires users to visit multiple websites, compare prices, read product specifications, and decide which product offers the best value. This process can be confusing and time-consuming, especially for users with a fixed budget or specific requirements.
We wanted to make online shopping smarter and simpler using Artificial Intelligence. This inspired us to build SmartCart AI, an intelligent shopping assistant that understands what users need and helps them make better purchasing decisions.
What it does
SmartCart AI is an AI-powered shopping assistant that allows users to interact through a conversational chatbot instead of relying only on traditional product searches.
Its key features include:
AI Shopping Assistant: Uses Gemini AI to understand natural-language shopping requests.
Smart Product Discovery: Finds relevant products based on user requirements.
Price Comparison: Searches multiple online shopping sources and compares available offers.
Personalized Recommendations: Suggests suitable products based on budget, preferences, ratings, and value for money.
Image-Based Search: Allows users to upload a product image to identify and find similar products.
Shopping History: Helps users revisit their previous searches.
Payment Integration: Integrates PayPal Checkout to support the purchasing experience.
How we built it
We developed SmartCart AI as a web application using modern web technologies and AI services.
Our technology stack includes:
Gemini AI API: For natural-language understanding, product identification, and intelligent recommendations.
Serper API: For retrieving product listings and shopping offers from online sources.
Next.js and React: For building the frontend and application interface.
Supabase: For database management and storing search history.
Clerk: For user authentication and account management.
PayPal Developer API: For payment processing and checkout integration.
When a user sends a shopping request, Gemini AI interprets the requirements and identifies suitable products. The application then uses Serper to retrieve relevant shopping offers. The backend processes the results and presents product comparisons and recommendations through an interactive chatbot interface.
Challenges we ran into
During development, we faced several technical challenges:
Integrating multiple APIs and ensuring they communicated correctly.
Making Gemini AI understand different shopping requirements and user preferences.
Retrieving relevant product information and filtering irrelevant shopping results.
Comparing prices and recommendations while maintaining useful and reliable results.
Integrating PayPal Checkout and understanding its order creation and payment verification process.
Designing a conversational interface that provides a smooth shopping experience.
We addressed these challenges through testing, debugging, API integration, and improvements to our application architecture.
