Shopanion Project Overview

Inspiration

Online shopping's biggest pain point: you can't try before you buy. 70% of returns happen because clothes don't fit as expected. We wanted to bring the fitting room experience to every website.

What it does

Shopanion is a universal Chrome extension that adds AI-powered virtual try-on to any shopping site. Upload your photo once, then instantly see how any clothing item fits you with photorealistic results. Generate short videos to share your looks and get personalized recommendations based on your style.

How we built it

Chrome Extension (MV3): Universal product detection and UI injection
MCP-A Service: FastAPI + Gemini AI for virtual try-on generation
MCP-B Service: FastAPI + MiniMax API for video animation
Redis caching: Sub-2s responses for popular items
Distributed architecture: Scalable microservices with clean API contracts

Challenges we ran into

Making AI try-on work universally across different e-commerce sites
Achieving photorealistic results while preserving body shape and pose
Optimizing latency to under 2 seconds with intelligent caching
Building a seamless UX that doesn't disrupt existing shopping flows

Accomplishments that we're proud of

Universal compatibility: Works on any shopping site without retailer integration
Performance: <2s cached responses, <5s fresh generations
Quality: Photorealistic try-on results that preserve user's body and background
Complete pipeline: From try-on to video generation to personalized recommendations
