Show HN: I made a cute, open-source Japanese learning app inspired by Monkeytype

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 main selling point: 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, an

d did it more out of curiosity. 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

Show HN: I made an App for learning Japanese, and it won in Vercel's OSS program

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.

Show HN: Open-source Japanese learning Platform inspired by Monkeytype

As a long time Japanese learner, I've always wanted there to be a simple, free online trainer for learning and grinding Japanese kanji and vocabulary - like Monkeytype in the typing community (fun fact: we actually have 2 Monkeytype devs on our team now!). I'm doing this because I grew tired of all the subscriptions and paywalls, which are unfortunately very common in the Japanese learning apps market. That's why I want to make the most fun, user-friendly and customizable platform for learning Japanese currently available, and the first one that is (and will be, forever) completely free, ad-free and open-source - driven not by profit, but made by the community, for the community. We already managed to get around 600 stars on GitHub and about 7k monthly users for the app. That being said, I recognize that the app is still in its very early
Read the rest
alpha stages and is, objectively speaking, behind paid Japanese learning solutions (at least for now) - which is why I want to change that and make it the first entirely free and open-source platform for learning Japanese to provide a real, high-quality alternative to all the current paid Japanese learning resources, which I believe we can achieve with the open-source community's help. Why am I doing this? Because weebs deserve to have a free, open-source learning platform too (I'm one of them, don't judge...) どうもありがとうございます!
