Choosing where to eat with friends sounds simple, but group decisions often become frustrating. Everyone has different schedules, budgets, dietary restrictions, and personal preferences, making it difficult to reach a decision that works for everyone. PickFight transforms this messy conversation into a structured and fun decision experience. A host creates a dinner room and invites friends with a simple room link. Each participant privately shares their availability, budget, food preferences, and dietary requirements. Personal answers remain private, while PickFight uses them to identify options that are feasible for the entire group. Instead of simply recommending popular restaurants, PickFight prioritizes compatibility. It first filters restaurants using safety requirements and hard constraints, then ranks remaining options based on group fit. The top candidates enter a tournament-style voting process where friends anonymously vote through head-to-head matchups until one winner emerges. By combining private preference collection, intelligent filtering, compatibility scoring, and social voting, PickFight helps groups stop debating and start deciding.
