There's a secret word at the bottom of the well. Each guess tells you how close in meaning you are — real cosine similarity between word vectors.
Type any word. I'll tell you its similarity to the secret. Warmer = closer in meaning. Find all three!
This is how a model represents meaning: words that appear in similar contexts get similar vectors, so "cat" sits near "dog" and far from "run". Embeddings turn meaning into distance.
