CodeMap Snapshot — Project Description
CodeMap Snapshot is an AI-powered code analysis tool that helps developers understand how changes between two versions of a GitHub repository may affect their project. It uses Gemma 4 to analyze code changes, explain their potential impact, highlight areas that need attention, and suggest what developers should review or test.
Users can provide a public GitHub repository and compare different branches, tags, or commit versions. The application identifies added, modified, and deleted code, then uses AI to generate an understandable summary of the changes and their possible consequences.
Key Features

• GitHub Repository Analysis: Analyze source code from public GitHub repositories.
• Snapshot Comparison: Compare two versions of a repository to identify code changes.
• AI-Powered Impact Analysis: Use Gemma 4 to explain the potential effects of code changes.
• Testing Recommendations: Suggest areas and functionality that developers should test after changes.
• Developer-Friendly Dashboard: Present code changes and AI-generated insights in an accessible interface.
• Improved Code Review: Help developers prioritize important changes and understand unfamiliar code more quickly.
  Problem It Solves
  Developers often struggle to understand the consequences of code changes, especially in large projects or unfamiliar codebases. Manually reviewing every change can be time-consuming and may cause important areas to be overlooked.
  CodeMap Snapshot simplifies this process by combining repository comparison with AI-generated explanations, helping developers make code reviews faster and more informed.
