CONTRA Take a stand. Defend your ideas. Change your opponent's mind. Contra is the first app that turns debate into a discipline. You pick a topic. You take a position. An argumentative AI takes the opposing side — trained to spot your weaknesses, exploit your blind spots, and defend its case until the end. Your only goal: make it change its mind. A precise measure of how you think. After every debate, a detailed score across four dimensions — Logic Ā· Rhetoric Ā· Evidence Ā· Originality — reveals where you excel and where you give ground. An AI coach walks back through each exchange, line by line, and shows you the counter-argument you could have made. Three ways to practice. — Solo. Four difficulty levels, from training to Brutal. The AI adapts to your skill and raises the bar as you progress. — 1v1 Challenges. Send a challenge to a friend. Same topic, same rules. The strongest case wins. — Public Arenas. Join live debates across eight major themes: politics, ethics, science, religion, culture, economics, sport, environment. A new topic, every day. What makes Contra different. — Real-time streaming debates. No rigid turns. The AI replies word by word, like a thought taking shape. — AI coaching after every debate. A critical read of your performance, and the counter-arguments you missed. — Full replay and history. Every debate saved, analyzable, comparable. Your progress, measured over time. — Leaderboards among friends. Streaks, badges, levels. Proof that you're improving — not just a feeling. Who is it for? Students, lawyers, negotiators, debaters, curious minds. For those who believe an idea's strength is measured by the force of its critics. Free. No ads. Unlimited debates with Contra Pro. 14-day free trial, no credit card required. Download Contra. Take a stand. Defend your ideas. Change your opponent's mind.
