AI English chat App

​2022年

This application is a sample design created as part of the Google certification program.

This chat service uses AI to help you learn English conversation on your own. Unlike regular English conversation lessons, there is no need to meet face-to-face with a person.

Mobile app mock up

The display portion of the analysis parameters on the results screen is mistaken for a button.

Therefore, I eliminated the frame and made it clear that it wasn't a button.

When starting a chat, you tap the button under "Chat theme," but the term "Chat theme" was difficult to understand. Therefore, the word "Chat theme" was replaced with the more direct word "Lesson”.
