Learning Japanese and Chinese just got faster

Memorize hanzi and kanji efficiently with mnemonics and gamification.


“Doctor Professor stands out among all other learning alternatives. The memo stories are fun and make it easier for students to build their vocabulary. When my students use the app independently in class, I get extra time to catch up with grading exams, a valuable benefit to me as a busy teacher.”
Fengping Mao, Chinese Teacher

"I studied Japanese for many years and struggled a lot to memorize the kanji. Doctor Professor changed it all for me. After a couple of months I had learned hundreds of new kanji and easily passed my exams at Waseda University, Tokyo. I would never have achieved this with traditional kanji learning methods."
Gustavo Maultasch, Diplomat

"My 9 year old son is a heritage learner growing up outside of Japan. Doctor Professor's illustrations and animations are fun and really help him learn the kanji. The app lets him follow the same kanji curriculum as kids in Japan do and he often scores 100% on his weekly quizzes at school. This is subarashii!"
Maiko Shimoda, parent


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.
