KotobaWeb is an extension of work I've done for my Discord Bot. In addition to the features here on the website, the bot has SRS, saving/loading, leaderboards, more question categories, plus other Japanese-related functions including dictionary searching, kanji searching, furigana rendering, and more.
If you have feedback or ideas, please let me know using the contact form. The code for the website is open source and contributions are welcome.
This site is built using React.js, Bootstrap Material Design, and Express.js.
The game data comes from various sources including Jisho, KANJIDIC, and Patrick Roos's kanjiquizbot.
The kanji stroke order graphics were generated using Kanimaji and KanjiVG.
The favicon comes from Icons8.
