Inspiration
Shopping for different needs can be confusing, especially when you have a budget and already own some of the things you need.
What it does
PayPal SmartCart AI lets shoppers describe what they want in their own words, set a budget, list items they already have, and add requirements. It finds real catalog products, recommends options that fit the budget, and lets shoppers review a cart for PayPal Sandbox checkout.
How we built it
We built a React and Vite frontend with a Python and FastAPI backend. Channel3 provides catalog search, and PayPal Sandbox handles checkout.
Challenges
We worked to support open-ended shopping requests, avoid recommending items the shopper already owns, and keep the total cost within budget.
What's next
We want to improve the shopping experience and make product comparisons clearer.
