Wolfcha is an AI-native social deduction game that simulates a full table of Werewolf players using large language models. Each AI player has a dual-layer roleplay system: an underlying virtual persona with unique personality, layered with a game role (Seer, Witch, Wolf, etc.) that drives strategic behavior and natural conversation. Players interact through generated dialogue, logical deduction, and bluffing entirely powered by LLMs, with the human player as the sole real participant at the table.
