Human or Not?
Human or Not? is a free chat game by AI21 where players talk with a hidden partner for two minutes and then guess whether they were chatting with a human or an AI.
About
Human or Not? is a free browser-based social experiment built by AI21, the Israeli AI company known for its work on large language models and enterprise model post-training. The game presents a modern take on Alan Turing's classic imitation game: each player is paired anonymously with either a real person or an AI language model, and after a two-minute text conversation they must decide which one they were talking to.
The concept is simple. Players open the site, start a chat, and type freely about anything they like. When the timer ends, the game reveals whether the conversation partner was human or machine, along with the correct answer. Beyond entertainment, the experiment gives researchers and the public a casual way to observe how convincingly modern conversational AI can mimic human dialogue, and AI21 has published aggregate findings from the game about how often people are fooled.
