About this app

Want to use the Japanese you have learned, but have no one to talk to or practice with? Unsure whether your Japanese is correct or fits the person and situation?

Motto! lets you practice with AI and turn mistakes and unnatural expressions into learning. Instead of only reading corrections, learn the related grammar, practice and test it, then use it again in conversation.

Talk with AI. Review corrected expressions and why they changed in your selected display language. Learn, practice, test, review, and use them again.
Motto! connects every step into one learning cycle.

【The Motto! learning cycle】

1. Practice Japanese with AI

Use Japanese at your own pace, with no partner or reservation needed. Set goals such as daily conversation, travel, work, or the Japanese-Language Proficiency Test (JLPT). Choose any topic and adjust the AI's response level. Supported devices also offer voice input.

2. Review mistakes and unnatural expressions

The AI checks your vocabulary and grammar, plus whether your expressions fit the person and situation set for the conversation. Review what you said, the corrected expression, and why it changed in your selected display language. Save corrections to your phrasebook to revisit or hear later.

3. Learn the related grammar

Motto! matches corrected expressions to relevant grammar materials and suggests what to learn next. Review each point's meaning, form, usage, notes, and examples in your selected display language, then choose what to study.

4. Check your understanding

Learn through lessons and practice questions, not just reading. Tests check your understanding and record results by grammar point. You can also use Ask AI for questions about lessons and test results.

5. Review, then use it again

Based on your results and time elapsed, Motto! organizes grammar due for review. Study and test it again, then use what you learned in conversation with AI.
