Vibe-coded web app for studying traditional Chinese characters

August 30, 2026

I have been studying Mandarin in the Mainland only focusing on simplified characters, but I wanted to increase my recognition ability of traditional characters. I also wanted an excuse to try out Codex more. So I made a small browser game that shows a traditional character and asks me to type its corresponding simplified form.

For example:

The quiz gives immediate feedback with the correct character, pinyin, and English definition. It also keeps track of accuracy while you play. I can optionally filter the character list by priority or by how well I already know each character, and download a CSV of your results when you finish.

Try it here: Traditional → Simplified Chinese character study game.

The game runs entirely in the browser, with the character data loaded from a CSV file, so there is no account or server required.
