Hintveil turns one iPhone into an imposter game for 3–12 friends. Give AI a theme and choose who’s playing, the age range, tone, and difficulty. It generates related word pairs, then checks relevance, safety, balance, and duplicates before you save and refine the deck. AI creates the content—not the suspicion; friends still give clues, debate, and vote. The offline game and decks are free. AI creation and editing require an active subscription and internet; saved decks remain playable offline.
