As someone who loves both coding and language learning (I’m learning Japanese right now), I always wished there was a free, open-source tool for learning Japanese, just like Monkeytype in the typing community.
Here’s the best part: I added a gazillion different color themes, fonts and other crazy customization options, inspired directly by Monkeytype. Also, I made the app resemble Duolingo, as that’s what I’m using to learn Japanese at the moment and it’s what a lot of language learners are already familiar with.
Miraculously, people loved the idea, and the project even managed to somehow hit 1k stars on GitHub now. Now, I’m looking to continue working on the project to see where I can take it next.
Back in January, I even applied to Vercel’s open-source software sponsorship program as a joke. I didn’t seriously expect to win, and did it more out of curiosity, fully expecting to lose.
Lo and behold, yesterday I woke up to an email saying the app has been accepted into Vercel’s Winter cohort. Crazy!

Anyway. Why am I doing all this? Because I’m a filthy weeb.
どうもありがとうございます!


Congrats.
I gave it a go just now and noticed an issue in the unit one vocab. You can get the prompt “to open” with both 開く and 開ける as options. Only one of these will be considered correct, and it’s a coin toss which one.
Also I got achievements for mastering all (N5-N1) kanji with 80% accuracy when I ended the session.
Maybe they should change 開ける to "to open something)
