Problem
How can learners practice language that fits the situation, relationship, and intent—not only grammatical correctness?
Role
Learning scenarios, feedback UI, multilingual implementation
Process
- Create goal-based scenarios for interviews, classes, and asking for help
- Explain feedback across grammar, naturalness, politeness, and intent
- Let learners retry the same intent with a different expression after feedback
Outcome
A working prototype is live with a five-language interface, streamed replies, situational correction and role-play, and references to official Japanese-learning sources.
Reflection
Showing a correct sentence is not enough; learning requires understanding why it changed and using it again.
