💊 MedWise: AI-Powered Medication Affordability Platform

💡 Inspiration

In the U.S. alone, millions of people struggle to afford their prescriptions—often unaware that generic alternatives exist at a fraction of the cost. The healthcare system is flooded with fragmented drug information, making it hard for patients to compare options. We created MedWise to simplify this process using AI and structured data, helping users make smarter, cost-effective medication decisions with just a search—or a photo of their prescription.

🔍 What It Actually Is

MedWise is a smart medication dashboard that connects users to cheaper, clinically equivalent alternatives to expensive brand-name drugs. It combines a powerful knowledge graph with AI to surface personalized, affordable options in two ways:

1. Manual Search Mode

Search any brand-name drug to view:

Generic equivalents
Prices
Active ingredients
Side effects
Drug interactions & treated conditions
Manufacturer details

2. Prescription Scan Mode (New)

Upload a prescription image and let AI handle the rest:

🧠 Gemini Vision parses drug names from the photo
🔗 Queries our Neo4j GraphRAG pipeline
💡 Returns cheaper, therapeutically equivalent medications automatically

🛠️ How We Built It

Frontend: Next.js, React, Tailwind CSS, TypeScript
Backend: Flask API connected to Neo4j AuraDB
Graph: 135+ nodes and 140+ relationships including prices, manufacturers, ingredients, and medical uses
AI Integration:
- Gemini Vision model for prescription parsing
- Hugging Face + Neo4j GraphRAG for medication reasoning
Performance: Redis caching, API routing via Next.js → Flask backend

⚔️ Challenges

Handling variability in prescription formats (digital, printed, handwritten)
Aligning extracted drug names with structured graph entities
Designing an intuitive UX that makes complex medical data approachable

✅ Accomplishments

Functional image-to-alternative medication pipeline
Accurate drug parsing using Gemini Vision
Built a scalable, visually interactive medication graph
Helped users explore and understand how to save on prescriptions
