## Overview

Carly AI is a medical-assistance and appointment-booking platform. A patient chats through the web interface; the client gathers patient details, requests AI-backed medical guidance and specialization matching, finds doctors and available slots, and submits a booking. The backend also supports a doctor portal and appointment notifications. Doctor availability and booking data are represented in repository files, while doctor credentials use SQLite. The README is brief and the server excerpts omit much route implementation, so uncertain subsystem wiring is not shown; the separate FastAPI service is documented as an alternative integration.

Main entry points: [`server.js`](https://github.com/daxeshchaudhary/internship_project/blob/main/server.js) (HTTP API), [`index.html`](https://github.com/daxeshchaudhary/internship_project/blob/main/index.html) (Patient Web UI), [`app.js`](https://github.com/daxeshchaudhary/internship_project/blob/main/app.js) (Conversation And Intake), [`knowledgeBaseReader.js`](https://github.com/daxeshchaudhary/internship_project/blob/main/knowledgeBaseReader.js) (Doctor Directory)
