DecisionBuddy – AI-Powered Product Comparison with Real-Time Data: A Technical Deep Dive

This paper explores the development and implementation of DecisionBuddy, an AI-powered product comparison engine that leverages real-time data scraping, Natural Language Understanding (NLU), and Generative AI (GenAI). Aimed at overcoming decision fatigue in e-commerce and product selection, the platform demonstrates a scalable architecture and efficient query-to-recommendation pipeline. We provide an end-to-end technical breakdown of its architecture, implementation challenges, intelligent query parsing, and GPT-powered summarization process. A working Proof of Concept (POC) validates the system’s efficiency and accuracy.
