JapanTalk

JapanTalk is a Japanese learning app where AI generates new Japanese conversations every time.

Simply select a topic and learning level, such as "Airport," "Ordering at an Izakaya," or "Weekend plans with a friend," and a natural Japanese conversation between two people is instantly generated.

▶ Recommended for:

• Those who want to study with real-life conversations rather than textbook examples

• Those who want to see an infinite number of new conversations on topics of their choice

• Those who want to study slowly, sentence by sentence, while reading the explanations

• Those preparing for the JLPT, travel conversation, or working holiday

▶ Key Features

• Automatic AI Japanese Conversation Generation

Enter your desired topic and level (Beginner/Elementary/Intermediate/Upper Intermediate/Advanced), and a natural conversation between two people of 6 to 8 lines will be generated. Since a new conversation is generated every time, you can study the same topic multiple times.

• Natural Korean Translation for Every Sentence

One line in Japanese, one line in Korean translation. Tap a sentence to toggle the Korean translation on and off. • In-depth Sentence-by-Sentence Explanations

Tap any sentence to receive an accurate translation, key words and expressions, grammar points, and even nuanced explanations on how they are used in actual situations and tones. Furigana (reading guides) are displayed alongside the Kanji.

• Listen to Natural Japanese Pronunciation

Tap a sentence or word to hear the pronunciation. You can choose between the device's built-in TTS and Gemini's high-quality AI voice, and you can also set separate A and B speaker voices.

• AI Background Images Depicting Scenes

New background images are generated every time to match the conversation context, helping you immerse yourself in learning.

• Favorites and Learning History

Save good sentences or words with a star, and all conversations you create are automatically saved in your history so you can retrieve them at any time.

▶ How to Use

1. Enter your Google Gemini API Key in Settings (issued for free at Google AI Studio).

2. Select the topic and level you want to study.

3. Watch and listen to AI-generated conversations to learn vocabulary and grammar in depth. ▶ Gemini API Key Guide

JapanTalk operates using a Google Gemini API key issued directly to the user. The API key is stored only on the user's device and is not transmitted to external servers. Since the free usage limit for the Gemini API is generous, there are virtually no costs for general learning use.

▶ Advertising

The app covers operating costs through Google AdMob ads. They are displayed minimally in locations that do not disrupt the learning flow.

▶ Privacy

• No sign-up or login is required.

• Learning history, favorites, and settings are all stored only on the device.

• The Gemini API key is also stored only on the device.

Enjoy studying with new Japanese conversations every day!
