AI Word Detective

Find the secret word. A language model scores how close each guess is in meaning.

How to play

  1. Type any single word and press Guess.
  2. Each guess gets a closeness score from 0 to 100. Higher means its meaning is nearer the secret word.
  3. Use your warmest guesses to steer the next ones. Your guesses stay sorted, closest first.
  4. Stuck? A category hint appears after 8 guesses, the first letter after 15 and the length after 22.
  5. Solve it in as few guesses as you can, then share your result or play a practice word.

How the AI works

Closeness comes from all-MiniLM-L6-v2, a small open-source sentence-embedding model. It turns each word into a list of numbers that reflects how the word is used in text; words used in similar ways end up close together.

The model downloads once (about 25 MB) and runs entirely in your browser, so your guesses aren't sent to a server. It measures usage, not dictionary meaning, so the occasional score will surprise you; that's part of the puzzle.
