## Overview

This is a browser-based AI document reader: users add or select PDFs and other supported files, inspect them, chat about a document, and launch analysis tools such as mind maps, comparisons, and quizzes. React’s App coordinates document and chat state and presents feature modals; an Express server owns the AI endpoints and streams chat responses from Gemini. The sampled files establish those main routes, but not the wiring or implementation of every listed tool, so uncertain API links are omitted.

Main entry points: [`src/App.tsx`](https://github.com/shekhar-commit/intellidocs-ai-enterprise-document-intelligence-platform/blob/master/src/App.tsx) (App Coordinator), [`server.ts`](https://github.com/shekhar-commit/intellidocs-ai-enterprise-document-intelligence-platform/blob/master/server.ts) (Express API), [`src/components/DocumentHubModal.tsx`](https://github.com/shekhar-commit/intellidocs-ai-enterprise-document-intelligence-platform/blob/master/src/components/DocumentHubModal.tsx) (Document Hub), [`src/components/ChatWindow.tsx`](https://github.com/shekhar-commit/intellidocs-ai-enterprise-document-intelligence-platform/blob/master/src/components/ChatWindow.tsx) (Document Chat)
