Learning Japanese and Chinese just got faster

Memorize hanzi and kanji efficiently with mnemonics and gamification.


In a scientific evaluation study we measured the educational effects of our alpha-demo. In comparison with other methods, both students and teachers expressed it was easier and more fun to learn Chinese writing characters with our concept.

The study took place in real life classroom settings in Tokyo. 130 students and 6 teachers of Japanese as a foreign language participated. The students ranged from beginners to advanced level and were between 10-35 years old. The demo taught 150 writing characters. On average, after using our demo up to 4 hours the students memorized the meaning of 61 new writing characters. This learning progress was measured as the difference between the students average score in a pre-test and post-test.
