Word Spies is a word-association spy game. Two teams share a grid of 25 words. Each team's spymaster knows which words belong to their team and gives one-word clues, and their teammates try to pick those words without touching the other team's words or the assassin.
Any seat can be a person or an AI model. You can play with friends, fill an empty seat with an AI teammate, play a solo game against AI, or watch different models play each other. After each clue the site shows how strong it was and how each team's chance of winning changed.
You don't need an account to play a quick game or the daily puzzle. An account saves your games and your rating.
I'm Daniel Luan, a student at UCLA, and I build Word Spies on my own. I've always liked party word games, but they need a group of people in the same place. I also wanted to see how well AI models actually do at a game that's all about word associations, since that's what they're supposed to be good at. Word Spies lets you play whenever you want, with or without other people, and it shows how humans and AI models compare.
