Kyo no Tegami
今日の手紙
your chosen language
Level up your language comprehension and composition skills
How it Works
Each day you receive a letter to read and comprehend.
You then craft a reply.
Kyo no Tegami tracks your score in the background over a variety of criteria identified by our language experts.
Your reply is evaluated across the many dimensions, and your score and skill level are adjusted.
Your next letter is automatically custom fit to your new skill level and understanding.
Day by day, the letters adjust to your abilities. In the case of Japanese, they gently nudge you to more challenging subject matter including grammar particles, kanji clusters, verbs, and more.
Little by little, day by day, almost imperceptibly, you'll get closer and closer to your stated goal.
Your goal could be to have a conversation, to navigate a menu, to go on dates, or to pass a standardized test. To study abroad, to work abroad, or to marry a native. Whatever your language learning goals are, Kyo no Tegami is here for you, every. single. day.
