This thesis presents the design of a system that utilizes Chatgpt as an auxiliary learning tool to assist students in overcoming learning difficulties. By providing pre-existing knowledge in relevant domains to GPT-3, the system enhances the accuracy of its responses. Additionally, the interface design enables students to ask high-quality questions and receive precise answers. The aim of this thesis is to utilize this system design to help students resolve learning problems, increase their motivation in learning, and reduce the development cost of chatbot systems in professional domains. It is envisioned that this design can be applied to a wide range of learning fields.
