What levels does Aki support?
Aki supports spoken conversation practice from N5 (beginner) through N3 (intermediate), plus a business Japanese track. You choose your level and goal when you first set up your account, and can change it anytime in Settings.
How does the AI conversation practice work?
Hold the mic button and speak Japanese for the given situation, then release when you're done. Aki responds with a natural spoken reply, just like talking to a real person. The app requires microphone permission — you can grant this in iOS Settings → Aki → Microphone.
Does Aki require an internet connection?
Yes. Aki uses cloud-based AI for real-time conversation and grading, which requires an active internet connection. If you lose connectivity mid-session, the conversation will pause until the connection is restored.
Is my voice stored?
Voice audio is processed in real time and is not stored as an audio file. However, the text transcript of your conversations (used to power progress tracking and review) is saved to your account. See our Privacy Policy for full details.
How does Aki find my weak points?
After each conversation, Aki analyzes what you said and flags mistakes by category — particles, grammar, natural phrasing. These are turned into short review drills in the Review tab so you can practice exactly what you keep getting wrong.
Why is the conversation slow or unresponsive?
This is usually caused by a weak internet connection. Try switching between Wi-Fi and mobile data. If the issue persists, force-close the app, wait a moment, and reopen it.
The app is crashing or not responding — what should I do?
Please try: (1) Force-close the app and reopen it. (2) Restart your device. (3) Update to the latest app version via the App Store. If the problem continues, email contact@gzlightek.com with your device model and iOS version.
How do I cancel a subscription or request a refund?
Subscriptions are managed through your Apple ID. Go to the App Store → your profile photo → Subscriptions to cancel. Refunds must be requested through Apple at reportaproblem.apple.com.
How do I delete my account and data?
