Branching dialogue
Conversations that fork
Fluency is handling the unexpected. Every turn has several paths, and your answer picks one.
- Your reply branches the story
- Same scene, different route
- The character adapts to what you said
Learn Japanese by actually speaking it
Hold the mic and speak. Nothing moves forward until you do.

On-device recognition
Not another flashcard app
Five things the drill-and-memorize apps won't do.
Voice-first
Say it right, or the AI waits
Hold to speak, release to be heard. The rhythm of a real conversation, not a tap-through quiz.
- On-device Japanese recognition
- Instant pronunciation feedback
- 100+ natural TTS voices
Weakness tracking
Five layers of diagnosis
You don't need to know where you're weak. Every sentence you speak is analyzed in the background.
- Morphology, syntax, lexis, pragmatics, phonology
- Errors land in your weak-words notebook
- Reviews come from your own history
Spaced repetition
Five levels, each one harder
Hints fade, then disappear. At the top levels the AI writes new material just for you.
- L1–L2: cloze with fading hints
- L3: AI variants in fresh contexts
- L4–L5: Japanese only, then full translation
JLPT & grammar
Vocabulary you say out loud
N5–N1 with furigana and bilingual examples. Build sentences aloud and the AI scores them live.
- Example, audio and furigana per word
- Speak-to-pass word challenges
- Live grammar scoring on your sentences
What practice actually looks like
Your answer picks the path
Order something complicated or keep it simple. The barista replies differently.
Mistakes become a training plan
The AI coach pulls today's review set from your own error history.
Scenes from real life
A rush-hour coffee order, a ticket at Hakone station, a lost stranger asking directions.
An AI that listens on five layers
Every sentence is diagnosed the way a teacher would, then turned into practice.
01
Morphology
Word forms and conjugation
02
Syntax
Structure and particles
03
Lexis
Whether the wording is natural
04
Pragmatics
Context and politeness
05
Phonology
Pronunciation accuracy
Practice the moments that actually happen
These ship with the app. Type any other topic and the AI builds the scene, illustration included.

Order something complicated, under pressure
A ticket at Hakone station
Fares, top-ups, fixing a mistake

Anything you type
Izakaya small talk, a leak to report…

For people who can read, but freeze up speaking
I had the N4 vocabulary and still froze. Speaking every day is what fixed it.
JLPT N4–N5 learners
Words, but no confidence
I'm moving to Japan for work. Branching scenes are the closest thing to real conversation I've found.
Future residents
Everyday survival Japanese
Years here and I still hesitate. The custom scenes match my actual life.
Long-term residents
Confidence in real situations
Frequently asked
Does speech recognition need internet?
No. The neural recognition engine runs on your device and is tuned for Japanese, so it works on a bad connection or none at all.
Which JLPT levels are covered?
N5 through N1. Every word ships with a bilingual example, audio and furigana.
How is this different from a chatbot?
A chatbot follows a script and accepts whatever you type. YuiTalk is voice-first and runs on a branching dialogue graph, so what you say out loud changes where the conversation goes.
What does five-layer diagnosis do?
It analyzes each sentence for morphology, syntax, lexis, pragmatics and phonology. Errors feed your weak-words notebook and the spaced-repetition deck built from your history.
Is there an Android version?
YuiTalk is iOS for now. Scenes and features are still expanding.
Stop studying Japanese. Start speaking it.
Practice the one thing other apps skip: opening your mouth.
