## Overview

Kairo is a browser-based AI chat application. Users can sign in or create an account, start or revisit conversations, and exchange messages with the chat service; the chat screen also supports document attachments. The sampled code shows route wiring, authentication state synchronization, conversation-history calls, and the chat invocation. Several listed feature modules, including Home, NewChat, and the database service implementation, were not excerpted, so their internal behavior and connections are not detailed here.

Main entry points: [`kairo/src/main.jsx`](https://github.com/syedsuhaibhasan/kairo/blob/main/kairo/src/main.jsx) (Route setup), [`kairo/src/components/Login.jsx`](https://github.com/syedsuhaibhasan/kairo/blob/main/kairo/src/components/Login.jsx) (Auth forms), [`kairo/src/components/Signup.jsx`](https://github.com/syedsuhaibhasan/kairo/blob/main/kairo/src/components/Signup.jsx) (Signup form), [`kairo/src/pages/Chat.jsx`](https://github.com/syedsuhaibhasan/kairo/blob/main/kairo/src/pages/Chat.jsx) (Chat screen)
