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.

• 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

After it's released to RubyGems.org, add it to your Gemfile: bundle add ai_summary Or install it manually: gem install ai_summary If you want to use the gem directly from GitHub before release: gem 'ai_summary', git: 'https://github.com/andersmarkc/ai_summary' Then run: bundle install

bundle exec rails runner 'AiSummary::SummaryGenerator.generate'

AiSummary::SummaryGenerator.generate

bundle exec rake ai_summary:generate # Default output: rails_summary.txt bundle exec rake ai_summary:generate[json] # Output: rails_summary.json bundle exec rake ai_summary:generate[yaml] # Output: rails_summary.yaml

By default, this will generate a rails_summary.txt file in your project root.
