RareJob, Inc. (hereafter, “RareJob”), which helps people visualize and improve their skills as an “AI assessment company”, released a “lesson AI assistant function” (β) to help users learn how to speak English by utilizing ChatGPT. A part of users can now use this function.

Background

AI chatbot ChatGPT of Open AI which was released in the winter of 2022 has received phenomenal attention for its high accuracy which enables natural responses as if it were talking to a human in the world, though it has only been less than six months since its release.
Many services and products in Japan started to introduce ChatGPT rapidly. More and more services and products incorporate ChatGPT and various usages of the chatbot were introduced in a wide range of businesses and learning. On the other hand, some people are struggling to take advantage of it by themselves or find an efficient way to use it due to its flexibility of function. Some services also seem to incorporate the function of ChatGPT in a clumsy way which cannot improve user experiences because it just wants to draw attention to their services by the name of the latest function “ChatGPT”.

A survey showed that some people answered, “I don’t understand what ChatGPT is like”, and “I cannot seem to make use of it” as the reason why they don’t want to use ChatGPT. It means that many people think it sounds difficult. Most people answered that they don’t need ChatGPT, but the reason for the answer can be that they may not be able to imagine how to use and recognize its necessity and possibility.

Simply type English or Japanese words or sentences into the text box on the lesson screen, and translations and recommended expressions are displayed. This is useful to carry out smooth English speaking lessons without interrupting the flow of conversation with a tutor. Unnecessary information will not be provided as a function of ChatGPT is limited partly. This has eliminated concerns about how to use ChatGPT, while at the same time providing users with a more effective and efficient English learning experience.
