## Overview

Understand-Anything analyzes a GitHub repository or uploaded ZIP, then presents an interactive codebase explorer with summaries, structure, a knowledge graph, Q&A, and tutorial chapters. The visible workflow runs from login and source selection in the React client through authenticated API routes, source-specific file collection, and AI analysis; chat uses analyzed context. The sampled analysis code confirms model-generated abstractions, chapter content, and answers, while the README documents broader analysis capabilities such as dependency mapping and incremental updates. Some UI and backend wiring is unsampled, so uncertain links are omitted.

Main entry points: [`server/index.js`](https://github.com/sanithreddy06/ai-powered-codebase-understanding-and-exploration-tool/blob/main/server/index.js) (API routes and sessions), [`client/src/components/ExplorerLayout.jsx`](https://github.com/sanithreddy06/ai-powered-codebase-understanding-and-exploration-tool/blob/main/client/src/components/ExplorerLayout.jsx) (Explorer and source choice), [`client/src/App.jsx`](https://github.com/sanithreddy06/ai-powered-codebase-understanding-and-exploration-tool/blob/main/client/src/App.jsx) (App state and requests), [`server/services/aiService.js`](https://github.com/sanithreddy06/ai-powered-codebase-understanding-and-exploration-tool/blob/main/server/services/aiService.js) (Analysis orchestration)
