What is conversation training?

A feature for practicing Korean by talking with AI characters for each theme and situation.

Besides voice input with the microphone, you can also type on the keyboard. During a conversation you can ask questions in Japanese and check corrections.

What is grammar training?

Training where you translate a Japanese sentence into Korean, and the AI tells you whether it is correct and gives feedback.

You do not have to take the lessons in order. Start with any lesson you like. You can review the questions you got wrong all at once from "Review weak points" on the Home screen.

What is the difference between the Free plan and the Premium plans?

Free plan: Study the free grammar lessons, and unlock other lessons for 7 days with one ticket each. AI conversations use one ticket to start and one ticket to extend. In audio training, you can listen to Beginner Lesson 1. Banner ads are shown in the app.

Premium plan: Study every grammar and audio training lesson and have AI conversations, all without tickets. Banner ads are shown in the app.

Premium Plus plan: Includes everything in Premium and removes in-app banner ads.

On every plan, an AI conversation lasts 20 minutes and can be extended once.

What are tickets?

Tickets are items used on the Free plan. They unlock grammar lessons and are used for AI conversations.

Grammar: Unlock a lesson that is not free with one ticket, and you can study it as many times as you like for 7 days.

AI conversation: Use one ticket to start a conversation and one ticket to extend it.

Tickets cannot be used for audio training. Lessons other than Beginner Lesson 1 are available on the Premium and Premium Plus plans.

You can check how many you have under "Tickets" in the Settings tab. On the same screen, you can get more by watching videos (up to 3 per day) or by purchasing them (3 or 10 tickets).
