The purpose of this study is to examine the definition and characteristics of ChatGPT in order to present the direction of self-directed learning to learners, and to explore the possibility of meeting the learning purpose when applying ChatGPT to learning. If the learning utilization of ChatGPT meets its purpose, the direction and method that can be used for English learning using artificial intelligence were studied. In this study, first, the definition and technical characteristics of ChatGPT were examined, second, the utilization of artificial intelligence was mentioned, and third, the application of ChatGPT to English learning was described. First, ChatGPT is an artificial intelligence system that learns based on vast amounts of data and responds to given questions. Second, ChatGPT, released by OpenAI on November 30, 2022, has the weakness of giving false and errors in answers, and users have complained that ChatGPT's ability is not completely reliable. However, the undeniable fact is that artificial intelligence technology will develop, and the future will be used by most of humanity. Third, ChatGPT has many problems in plagiarism or imitation for answers and writing, and most educational institutions prohibit the use of ChatGPT. Despite these controversies, some argue that using ChatGPT as a learning assistant role can produce excellent learning outcomes. In particular, ChatGPT, which gives the most effective answer when using English as the main language, can help learning English, and can be used as a learning aid depending on the learner's ability. When using ChatGPT as a learning aid, it is expected that learners can lead self-directed learning and be interested in the learning environment, but it is necessary to pay attention to errors in ChatGPT when using it.
