Japanese practice in bite-size tests

Built to make Japanese stick

Short enough to do every day. Thorough enough to count.

1. 毎

   A habit you can keep

   A test takes about 15 minutes, so it fits into any day, even a busy one. A little every day beats a long session once a week, and your streak keeps you coming back.

2. 復

   Spaced repetition, built in

   You remember best what you meet again just as you start to forget it. Baito brings back the words you missed after a day, three days, a week, two weeks and a month, keeps every wrong answer for review, and returns to the same grammar across tests.

3. 深

   Deep practice, not trivia

   Every test follows the real exam: vocabulary, grammar and reading, in its sections and order, with its Japanese instructions. You meet words in full sentences and passages, and each explanation says why the wrong answers are wrong, so you learn the rule, not just the answer.
