# PromptQuorum > One prompt. Every model. One verdict. PromptQuorum is a multi-model AI dispatch and consensus tool. Write one structured prompt, send it simultaneously to ChatGPT, Claude, Gemini and 25+ AI models, then run consensus analysis across all responses — hallucination detection, contradiction scoring, best-answer extraction. 100% private: API keys stay in your browser, no data reaches PromptQuorum servers. ## Product - **Primary use case**: Dispatch a single prompt to 25+ AI models simultaneously and analyze consensus across all responses - **Category**: AI Tools / Multi-model workspace / Prompt engineering - **Pricing**: Free.
