About this game
You can narrow down the secret word in two ways: by guessing a word and seeing whether its meaning is closer to the target, or by asking the Keeper questions such as whether the word is a type of fruit, which it answers with yes, no, or not sure without revealing the answer. The game works by turning words into embeddings, lists of numbers that capture how words are used semantically, so words used in similar ways get similar values. It is free, requires no login, and runs on both web and iOS; the web version uses Gemini's embedding API, while single-player on iOS relies on on-device Apple intelligence and Apple's built-in English embeddings. The interface is in English.
