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 · Rhetoric · Evidence · 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.
