Inspiration
Online shopping has become part of everyday life, but discovering the right products, making informed purchasing decisions, managing payments and understanding payment protection can still feel disconnected.
I wanted to build something that brings these experiences closer together.
That idea inspired PayPilot AI — an AI-powered digital commerce assistant designed to make shopping more intelligent, payments more accessible and financial learning more engaging.
What it does
PayPilot AI combines four key experiences:
- AI Shopping Assistant: Helps users explore products, receive shopping assistance and make more informed decisions.
- Product Marketplace: Provides a product discovery experience.
- PayPal Integration: Demonstrates payment workflows through PayPal Sandbox, including successful and cancelled transactions.
- PayPal IQ: An interactive financial education experience featuring daily facts, knowledge quizzes and learning progress.
The goal is to connect product discovery, shopping assistance, payment experiences and financial education within one platform.
How we built it
PayPilot AI was developed using React, TypeScript and Vite for the frontend, with Python and FastAPI powering the backend.
SQLite provides local data persistence, while OpenAI powers the AI shopping experience. PayPal Sandbox provides the payment integration and transaction testing environment.
The application brings these components together through API-driven workflows, with customer and administrative functionality supporting the platform.
Challenges we faced
One of the biggest challenges was integrating different capabilities into one working application without compromising existing functionality.
Connecting the frontend and backend, handling authentication, integrating PayPal Sandbox, validating payment scenarios and building an interactive financial learning experience required careful development and testing.
We also focused on making the shopping assistant more useful by moving toward product-aware recommendations rather than generic responses.
What we learned
Building PayPilot AI strengthened our understanding of full-stack development, AI integration, payment APIs, backend validation, transaction workflows and user experience design.
We learned that building a useful AI-powered commerce platform requires more than adding a chatbot. It requires connecting AI assistance to real application data, reliable backend processes and meaningful user experiences.
What's next
Our vision is to continue developing PayPilot AI into a more intelligent digital commerce platform, with deeper catalogue-grounded recommendations, improved shopping journeys and expanded financial education.
