FAQ
What is Kotoba?
A daily Japanese word game in the Contexto / Semantle family. One secret word a day — guess words and use their closeness ranks to zero in on it.
How is the rank calculated?
Every word in our 7,500+ word JLPT-tagged dictionary is compared to the secret word by meaning (semantic similarity). Rank #1 is the secret word itself; #2 is the closest neighbor, and so on.
Which words can I guess?
Any word in the dictionary — the same 7,500+ JLPT N5–N1 words you study in the app. The autocomplete accepts kana, kanji, romaji, and English meanings, so you never need a Japanese keyboard.
Is it good Japanese practice?
Yes — each guess is retrieval practice. You recall words by meaning, see their kana reading, English gloss, and JLPT level, and the answer is always a common N5–N3 word worth knowing.
