Turn listening into speaking
Understanding Korean and producing it are different skills. Every Renza session is pure production, so the gap finally closes.
한국어
Speak the Korean you only ever read and hear
You catch the dramas without subtitles and you’ve memorized the grammar. The missing piece is your own voice. Renza gives you someone to actually talk to, at your level, whenever you want.

Questions, answered
Is this just a chatbot?
No. A general AI assistant is brilliant, but it does not hold your level, stay in a scenario, give you a structured report, track the mistakes you keep making, or build a review deck from them. Renza is built to do nothing but that. It is the difference between asking an AI things and having a coach.
Will I become fluent?
Renza will not make you fluent on its own. Nothing will. But the thing blocking most people is not knowledge, it is never actually speaking. We fix that part, in short sessions you can do every day.
Do I need a microphone?
Yes. Renza runs in your browser and we check your mic when you sign up. Headphones help, but any working mic is enough.
What if I am a complete beginner?
Start at A1, N5, or TOPIK 1. The first scenarios are extremely gentle, the AI scaffolds in the target language, and you can leave English help on while you find your feet.
Can I switch languages?
Yes, any time from Settings. Your progress is saved separately for each language, so switching back puts everything exactly where you left it.
Is my call recorded?
Audio is processed to generate your transcript and report. You can delete your data and your account any time from Settings. See the privacy policy for retention details.
Can I cancel any time?
Yes, from Settings. No retention emails, no haggling.
