The word guessing game Contexto is built on contextual similarity. Players can try to guess a word as many times as they want and get hints about how similar their guess is to the secret word. Artificial intelligence looks at each guess and compares it to thousands of other texts. It then tells you how relevant the guess is to the context and how similar it is to the end word. In contrast to Wordle, Contexto is more concerned with similar meanings and situations than with proper spelling and letter placement.
