Conjugation Lab
Build Japanese conjugations into muscle memory.
You've probably learned the rules already. The hard part is seeing 行く and getting to 行って without stopping to think. Katachi drills just that: one prompt after another, and the ones you miss come back until the answer shows up on its own.

Why you stall
You know the rules. Sentences still trip you up.
Ask about the past, negative, te-form, potential, passive, causative or conditional one at a time and you can probably answer. Then one turns up in a sentence you are reading, or one you are trying to say, and you are back to running through the table in your head.
Textbooks teach the rules and flashcards hand you the answers. Practicing until you don't have to think is usually left to you. That is the part Katachi does.

How to practice
Four ways to practice
If you don't want to decide, do the daily set. To fix a weak spot or cram one grammar point before a test, use one of the other three.
02
Weakness Training
Goes through your mistakes and drills the few forms you get wrong most often.
03
Free Practice
Mix any level, word type and form. Useful when you want to run causatives over and over the night before a test.
04
Sentence Practice
One word across several sentences. Read the context, then pick or type the form that fits.
Open it and start.
Start practicingNothing to set up
Pick a level from N5 to N1, tick verbs or adjectives, and go. Katachi chooses the questions.
It remembers what you miss
If you keep missing te-forms, it notices. After a set it tells you which form was shakiest and offers five more questions on it. That takes about two minutes.
Pick or type
Multiple choice trains speed. Typing makes you come up with the form yourself. Choose the mode in practice settings before starting a set.
Daily streak
One short set a day does more than an hour of cramming on Sunday.

More words, same rules
Words are sorted by reference JLPT level, N5 through N1, so start with the ones at your level. As you move up, the words change but the conjugation rules stay the same, which is why they keep getting easier.
To be clear, this is conjugation practice, not a full JLPT course. Not every word comes with every form, and sentence practice uses a limited set of examples we checked by hand.
