One of the cleaner ways researchers estimate someone's vocabulary is a lexical decision task: you see a stream of real words and plausible fakes, and hit yes or no for each. Your score is accuracy on the real words minus a penalty for false alarms.

I took LexCHI (a Chinese vocabulary test published in Behavior Research Methods) and built a free, anonymous web version. It takes about two minutes and gives you a normalized Ghent score plus a tier reading adjusted for your level.

Give it a go at https://lexchi.hsk.band/ and maybe share your score and self-assessed level in the comments. Curious to see how they line up.
