Turing Test Live

A free browser game of the imitation game: as interrogator you question two witnesses — one human, one a current language model such as GPT-4 or Claude — and guess which is which, with identities revealed at the end of each round. You can also play as a witness.

Why I recommend it: Free and the fastest way to build real intuition about what current models sound like — worth twenty minutes before you rely on spotting AI text by feel. It proves nothing about consciousness or intelligence; it measures whether you can be fooled in a short chat, which is a fact about the conversation format as much as about the model.
