What is Contexto?
Contexto is a word guessing game based on meaning. You type a word, and the game tells you how close it is to the secret answer by giving it a rank from 1 to over 1000. Rank 1 is the word itself. The lower the number, the closer you are.
Rankings come from word embeddings - a way of measuring how often words appear in similar contexts across real text. If two words regularly show up near each other in books, articles, and web pages, they get close ranks. It is about meaning and usage, not spelling or rhyming.
