Quiz Battle

AI generates questions, compete head-to-head in real-time

Fun

The Problem

Trivia games have stale questions; finding good questions is hard; can't customize topics

Current Solutions (Not Great)

Trivia apps (same questions), pub quizzes (scheduled), making your own (tedious)

Who Needs This

Trivia enthusiasts, friends who compete, educators, bar trivia lovers

Trivia games with friends require someone to find questions or use stale question banks. Quiz Battle connects two players peer-to-peer and AI generates fresh, customized questions in real-time—on any topic you choose. Both players see the same question simultaneously, race to answer, and AI judges correctness (including partial credit for close answers). Every game is unique, topics are unlimited, and there's no server tracking your performance.

Honest Take

Trivia game market is crazy saturated (Kahoot, Quizizz, Trivia Crack, etc.), but the AI-generated fresh questions angle is legitimately novel—no more memorizing question banks. Technically straightforward to build, demos well, but monetization will be tough in a sea of free alternatives.

Build Prompt

Use this prompt with an AI assistant to start building

Build a React PWA called 'Quiz Battle' using WebInfer and WebRTC. Connection: DataChannel for game state. Game setup: players agree on topic (e.g., 'World History', 'Marvel Movies', '90s Music', custom), difficulty (easy/medium/hard), number of questions. Host's AI generates questions. Use generateObject to return { question: string, correctAnswer: string, acceptableAnswers: string[], hints: string[], difficulty: number, funFact: string }. Sync question reveal: host sends question with timestamp, both UIs reveal at same time. Players type answers, submit with timestamp. Answer evaluation: each player's AI checks opponent's answer against correctAnswer/acceptableAnswers, returns { correct: boolean, partialCredit: number, explanation: string }. Score: base points + speed bonus (faster = more points). UI: question display, answer input, opponent's answer (revealed after both submit), score display, timer. Sound effects via Web Audio API. Match end: final scores, fun facts from each question, rematch button. 'Topic roulette' mode: random topics each round.
