Build an AI Document Summarizer with Ruby on Rails 8.1

Build an AI Document Summarizer with Ruby on Rails 8.1 In Part of this Ruby on Rails tutorial series, we integrate our document summarization service into DocuMind AI. In this episode, we'll connect the service to the Rails controller, process document content, save the summary and key points to PostgreSQL, and display the results directly on the document detail page. What You'll Learn Integrate a service object into a Rails controller Build a document summarization workflow Generate summaries and key points using a mock AI provider Save summarization results to PostgreSQL Display AI summary results in the browser Test the complete workflow in a Rails application Tech Stack Ruby on Rails 8.1 Ruby PostgreSQL ERB and CSS Rails Service Objects No AI API Key Required This tutorial uses a mock AI provider to demonstrate the complete integration workflow without requiring a paid AI API key. The summarization logic is simulated and does not use a real AI model yet. Project DocuMind AI — an AI-inspired document management and summarization application built with Ruby on Rails.
