CodeDNA

**CodeDNA – AI-Powered Codebase Intelligence and Investigation** CodeDNA is an AI-powered software engineering investigation platform that helps developers understand unfamiliar codebases and investigate bugs more efficiently. Developers working with large repositories often spend significant time tracing dependencies, understanding execution flows, locating relevant code, and identifying the root cause of issues. CodeDNA addresses this challenge by combining source-code analysis, dependency graphs, repository history, and AI-assisted investigation. Developers can connect a GitHub repository, ingest its source code, and explore relationships between files, functions, and components. When given a bug report or technical question, CodeDNA retrieves relevant evidence from the repository and uses it to generate an investigation with supporting code references. The platform is built using React, TypeScript, FastAPI, Tree-sitter, Neo4j, and LangGraph. Our goal is to move beyond simple code search and build an intelligent engineering assistant that helps developers understand why something is happening, where the problem originates, and what changes could resolve it.
