HealthWise

Inspiration

Access to affordable, secure, and intelligent healthcare is still a challenge for many. We were inspired to create HealthWise as a decentralized healthcare companion that not only connects patients with doctors but also leverages AI and blockchain to make medical assistance more accessible, trustworthy, and proactive. From smart diagnosis to mental health checks — we wanted to build a Web3-powered, AI-integrated solution that puts the patient first.

What it does

HealthWise is a full-stack healthcare web application that empowers users to:

🔗 Book appointments with certified doctors based on specialization and availability.

🤖 Chat with an AI medical companion built using Gemini API, capable of answering health-related queries.

🩺 Take diabetes and depression screenings via AI classifiers built into the web app.

🧠 Get follow-up support, such as explaining previous prescriptions or tracking symptoms.

🔐 Securely store health records and appointment data using Hyperledger Fabric, ensuring data privacy and trust.

How we built it

Using Hyperledger Fabric, Express, React, Tailwindcss, MongoDb, Google gemini api

Challenges we ran into

Implementing Hyperledger Fabric for healthcare data required careful design

For some of us, it was our first time working with React.

Getting the Gemini LLM to respond accurately in a healthcare context was tricky. We had to experiment a lot with prompt engineering to reduce hallucinations and maintain clarity in answers.

Integrating our diabetes and depression classifiers into the web app and connecting them with user input forms was technically challenging.
