E-commerce AI Agent

An e-commerce AI Agent built with Langchain.rb and OpenAI. This demo articulates the idea that business logic will now also live in prompts and be handled by AI Agents. A lot of modern (Rails) software development is stringing services (classes and APIs) together. This demo illustrate how AI can assist in executing business logic and orchestrating calls to various services.
