AiSummary

AI-powered summary generator for Ruby on Rails applications.
AiSummary scans your Rails project and creates a structured summary of your models, database tables, associations, controllers, and routes. It’s designed to help AI tools (like ChatGPT or GitHub Copilot) better understand your codebase for debugging, refactoring, onboarding, or generating code.

✨ Features

  • Lists all models and their database columns
  • Extracts ActiveRecord associations (has_many, belongs_to, etc.)
  • Summarizes all controllers and public methods
  • Extracts and maps all routes to their controller actions
  • Outputs a clean .txt file (YAML and JSON output planned)
  • Useful for documentation, developer onboarding, and AI integration

📦 Installation
