Choppelganger

Type any topic, get instant AI quiz questions, and play with friends. No accounts, no ads — just grab a room code and go.

Think you know your stuff? Prove it — and catch the one who's faking it.

Choppelganger is a fast multiplayer social deduction game built around quiz questions. One player is secretly the Choppelganger — they don't actually know the material. Everyone else has to figure out who it is before time runs out.

HOW TO PLAY → Share a room code with your group → Answer multiple choice questions on any topic → Chat and debate during discussion rounds → Vote out the player you think is bluffing → The Choppelganger wins by flying under the radar. Everyone else wins by catching them.
