NutriQuest: Gamified Sustainable Grocery Assistant

🚀 Overview

NutriQuest is an AI-powered, gamified grocery assistant designed to help users shop smarter, eat healthier, and reduce food waste. By integrating AI-driven nutrition analysis, smart expiry tracking, and gamification, NutriQuest ensures that users make informed food choices while staying engaged through leaderboards, challenges, and rewards.

Our platform encourages sustainable shopping habits by analyzing grocery purchases, predicting missing nutrients, and offering personalized grocery recommendations to help users maintain a balanced diet.

🔥 Inspiration

Food waste and unhealthy eating habits remain major global challenges:

⚡ Over 30-40% of food is wasted annually in the U.S., costing approximately $473 billion.
⚡ Consumers struggle with tracking food expiration, leading to unnecessary waste.
⚡ The lack of a front-of-package ranking system makes it difficult to evaluate food sustainability and nutritional value at a glance.
⚡ Healthy eating is often perceived as inconvenient, and there's a need for engaging solutions that promote better habits.

We wanted to create an all-in-one grocery assistant that combines AI, sustainability tracking, and gamification to transform grocery shopping into an engaging and rewarding experience.

⚡ What It Does

NutriQuest provides a suite of features that help users track, plan, and optimize their grocery shopping experience:

✅ Scan & Analyze: Instantly get nutrition and sustainability scores for grocery items using barcode scanning.
✅ Smart Expiry Alerts: Track food expiration and receive AI-powered recipe suggestions to use items before they go bad.
✅ Gamify Your Impact: Earn badges, compete on leaderboards, and complete eco-challenges for sustainable grocery shopping.
✅ AI NutriBalance Planner: Generate personalized grocery lists based on inventory, dietary preferences, and missing nutrients.
✅ Leaderboard & Social Engagement: Compete with friends and the community to become a top sustainable shopper.
