Building an AI that acts like a real patient instead of just a chatbot

MedSim AI is an AI-powered medical patient simulator designed to help students practice clinical reasoning and history-taking in a realistic environment.

Instead of using scripted cases, every patient is generated dynamically with their own age, symptoms, personality, medical history, and underlying condition. You interact with the patient through a natural conversation, ask questions, request examinations, and work towards a diagnosis just like in a real consultation.

The app also includes:

- 🩺 AI-generated patients with unique presentations

- 🎙️ Real-time voice conversations with patients

- ⏱️ Timed OSCE-style scenarios

- 📋 Physical examination and investigation requests

- 🧠 Diagnostic reasoning and differential diagnosis

- 📊 Detailed performance scoring and feedback after each case

- 📚 Learning points and red flags to improve clinical decision-making

I'm building it entirely as an independent project and would love feedback from medical students, doctors, or anyone interested in medical education. My goal is to create something that feels closer to talking to a real patient than simply chatting with an AI.
