Name: Debasish Kumar Sahoo
Registration Number: 25BAI10173
Subject: Fundamentals of AI/ML

Project Overview

This project implements a rule-based conversational medical assistant using the Google Gemini API. The system conducts a structured 10-question diagnostic interview designed to gather symptoms and basic medical information from a user. After all ten responses are collected, the system generates a probable assessment along with a disclaimer.

This project demonstrates practical application of:

• Prompt engineering
• Multi-turn conversational AI
• System instructions in LLM-based applications
• Error handling and API integration

This is not a real medical diagnostic tool and is created strictly for academic purposes.
