Codexa - Explore Codebases as Interactive Systems

Codexa is an AI-powered platform that helps students and developers understand real-world GitHub repositories through interactive visual learning. Understanding unfamiliar codebases is often overwhelming due to complex architectures, deeply nested folders, and hundreds of files with no clear starting point. Most users end up jumping randomly between files trying to understand how the system works, which makes learning slow and frustrating. Codexa solves this by transforming repositories into simplified system maps where each node represents an important concept such as Authentication, APIs, Databases, Frontend Logic, or Routing. Instead of reading files manually, users explore repositories visually through guided learning paths and AI-powered explanations. Powered by Gemini AI, Codexa analyzes repository structures, identifies key concepts, and generates contextual explanations grounded in the actual codebase. Users can interact with the platform through concept exploration, AI tutoring, concept comparison, and flow tracing for actions such as user login or API requests. One of the most powerful features of Codexa is the “System Story,” which generates a complete step-by-step explanation of how the entire repository works. This helps users quickly understand architecture, module relationships, and data flow without manually exploring hundreds of files. By combining visual learning, guided exploration, and Gemini-powered intelligence, Codexa transforms how developers learn codebases — from reading files to exploring systems.
