Your Japanese school, from practice to payment.
Sensei is where your students practise between lessons — and where you finally see exactly which kanji, which verbs, which readings each one is losing. Rosters, worksheets, scheduling and booking in one calm dashboard.
Works the same whether you teach four students or four hundred.

Practice between lessons, visible to the teacher — the loop Sensei is built around.
Between lessons, you're flying blind.
Your students spend far more time away from you than with you. What happens in that gap decides whether they reach N3 — and today you can't see any of it.
Students drift
Reviews slip, the queue grows, and by the next lesson three weeks of kanji have quietly gone.
You re-teach from memory
You rebuild last lesson from what you can remember, not from what they actually got wrong.
No shared picture
They can't see what to work on. You can't see whether they did. Nobody's holding the thread.
Three moves. One loop.
Sensei turns the time between lessons into signal you can teach from — and closes the loop every week.
Students practise
Spaced repetition across words, verbs, phrases, kanji and grammar — tuned to their JLPT level, not a generic deck.
You see the gaps
Every miss is logged. The console shows the words they keep dropping, the types they're weakest in, and where they've stalled.
You prep the lesson
Sensei drafts the focus list from real review data. You edit it, assign words, and email the worksheet.
Every student, in focus.
Open a student and see, in seconds, exactly where they are and what to do next. No spreadsheets, no guessing.
Your roster at a glance
Every student with their JLPT level and a live activity dot — who studied today, who's been gone a week, who never started.
See what they're struggling with
The words they keep missing and the types they're weakest in, drawn straight from real review results — not a self-report.
Focus for next lesson
Sensei suggests what to cover from weak spots, overdue reviews and inactivity. You keep, edit or bin each one. Nothing auto-enters.
Assign vocabulary in a click
Pick a level and a type and the words land in that student's queue before they next open the app.
One bad day shouldn't erase a month.
A calm, honest study app built for real Japanese — SM-2 scheduling that bends when they struggle instead of throwing the work away.
Spaced repetition that forgives
Rate a card 1 or 2 and Sensei steps the interval back instead of resetting it — keeping 45–70% of the progress a hard reset would wipe.
N5 to N1, blended automatically
The progression rail keeps them on their level until they've mastered 70–80% of it, then folds the next level in gradually rather than all at once.
Pronunciation you can check
Tap the mic, say the word, and get a match score against the expected reading — with a running success rate per word. Nothing is recorded or stored.
The mix adapts to the weakness
Any type slipping under 70% accuracy gets more airtime in the next sessions, automatically, until it recovers.
Your focus this week
Their dashboard shows exactly what you asked them to work on, and their next lesson, the moment they log in.
Say it, score it, fix it — pronunciation practice runs on the same cards they're already reviewing.
The whole school, one console.
Provision teachers, group students into classes, and keep one clear view of the entire school — enrolment to progress.
- Add teachers and let them run their own rosters
- Group students into classes and re-assign them in two clicks

Booking and payments, already built.
The business side isn't on a roadmap here — worksheets and calendar invites are running today, and card payments switch on with a key.
Practice worksheets by email
One click turns a student's focus list and weak words into a worksheet and sends it to their inbox.
Lessons with calendar invites
Schedule a lesson and Sensei emails a proper calendar invite. They confirm from the email; cancellations update the calendar.
Card payments per lesson
Stripe checkout is built and tested — students book, pay, and the lesson confirms itself. Switch it on when you're ready to charge.
