One model.
Every dimension.

Speaking, listening, reading, writing — tracked independently. Every word across five mastery stages. The system sees where you're strong and where the gaps are.

Advancing past Apprentice requires producing the word in conversation — not just recognizing it.
01
Always current
Every turn, tap, and flashcard writes to the same model in real time.
02
Everything reads from it
Conversations, reviews, clips, and lessons all draw from one source.
03
Becomes irreplaceable
Six months in, no other app can replicate what this knows about you.

Rigorous structure, delivered through
real conversation.

Grammar
Systematic grammar, taught in context
Every pattern is sequenced and tracked — but you encounter it in conversation, not a textbook. You advance only when you can produce it.
📖
Vocabulary
Words you'll actually use, when you need them
Frequency-ranked, introduced through dialogue, reinforced by flashcards drawn from your own conversations.
🎭
Pragmatics
Sound right — not just be correct
Formality, indirectness, social nuance. The unspoken rules textbooks barely cover.
💬
Production
You speak from day one
No tapping, matching, or selecting. You generate language from scratch every session.
🎯
The goal is always conversational fluency
Everything in Linguist exists in service of one thing: holding a real conversation in Japanese.

Five dimensions of fluency.
One seamless system.

Unified knowledge model
One live graph. Every activity updates it. No more siloed apps.
💬
Purposeful conversations
Every chat has a hidden challenge layer targeting your weak points.
Grammar when you're ready
New patterns unlock only when your foundation can support them.
SRS that listens
Produce a word in conversation and its review interval extends automatically.
Native content, calibrated
Real clips shown only when you'll understand enough to acquire.
📈
Progress you can feel
30-day proof reports show growth in sentences you can now read.

You choose what to do.
The system chooses what's inside it.

01
Have a conversation

The system already knows your level, what's slipping, and what to push. Every session has a purpose you never have to set.

毎日の会話練習
02
A small, personal review

Flashcards drawn from your own conversations. Words you're about to forget. Never generic, never more than needed.

スマートな復習
03
Watch and read real Japanese

Native clips calibrated to your level. Every lookup updates the model. Five minutes on the train is never wasted.
