How it works
One loop, from a video to knowing where you stand
The same five steps whether you are studying alone or running a class. Only the last one differs.
- Step 1
Bring real content
Paste a YouTube link or an article URL. It becomes a lesson you can read, in the language you are learning.
- Step 2
Understand it in context
Tap any word for its reading and meaning — looked up against the sentence it sits in, not in isolation.
- Step 3
Save what matters
Keep the words and grammar you want to own. Everything you already know stays out of the way.
- Step 4
Review until it sticks
Saved items go into spaced repetition and come back to you on a schedule instead of all at once.
Step 5
See where you actually stand
Studying on your own
Your reading and review feed a progress view for the JLPT or HSK level you are aiming at, so preparation is something you can look at rather than guess about.
Teaching a class
The same lessons become assignments. You see who has done them, who has not, and which words the class keeps getting wrong.
See the teacher toolsSee how it works
One worked example, for each way people use it
Both walkthroughs below are illustrations of the actual screens, using sample content. They are not customer accounts.
A learner, start to finish
One video, followed all the way through to a progress view.
- 1
Bring in a video
youtube.com/watch?v=…
The transcript becomes a lesson in Japanese.
- 2
Tap a word you do not know
今日は新しい本を読みます。
あたらしい — new. Shown for this sentence, not as a list of every possible sense.
- 3
Save it, skip the rest
新しいgoes to your vocabulary. Words you already know do not.
- 4
It comes back before you forget
Saved items enter spaced repetition and are scheduled rather than dumped on you in one sitting.
- 5
Progress toward the exam
Coverage of the vocabulary, kanji and grammar for your target JLPT or HSK level fills in as you read and review.
A teacher, start to finish
The same lesson, turned into homework and then into something you can act on.
- 1
Make the lesson once
Import an article or video, or start from a worksheet you already use.
- 2
Assign it to a class
Students join with a code. They do not need their own paid plan to do the work you set.
- 3
See where the class is stuck
Sample data
- Student 1Completed
- Student 2In progress
- Student 3Not started
Plus which words the class as a whole keeps getting wrong.

Do I need a card to try it?
No. A new account gets 14 days of Ultimate free, a teacher account gets 30 days, and neither asks for a card. When a trial ends you drop to Free rather than being charged.
Is “unlimited AI” really unlimited?
It is not, and we would rather say so. Every plan has a stated monthly allowance — the row above. They are set well above normal use and exist so one heavy account cannot run up the bill for everyone.
Do my students need to pay?
No. Students join a class with a code and do the work you set without a plan of their own. Seats are counted on the teacher's plan.
What 14 supported languages actually means
Every language gets the reader and the AI features. Exam tooling does not spread evenly, because it depends on the exam publishing a word list — so here is the boundary rather than a single tick.
