Everyone has an opinion. Few can defend one. Take on an AI that always argues the opposite side, and have your case scored out of 100. 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. 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.

NEW — Against the Platforms Pick a candidacy from France's 2027 presidential race and debate its published platform. The AI defends only what the platform actually says: take it somewhere the platform doesn't go, and it will tell you so. NEW — A hand mid-debate Stuck halfway through an exchange? Ask for a hint. It knows which side you are defending, which side the AI is on, and what was just said — and it closes with one tap when you are done with it. IMPROVEMENTS • Redesigned home: today's debate first, one obvious next move, and our own illustrations instead of emojis. • Badges: what you just earned, and what is left before the next tier. • Stats: every criterion now says what it measures, and the screen tells you what to work on first. • Profile and settings split apart, with your weekly streak in plain sight. • Friends: empty screens now say what to do, and the invite link finally opens a real page. • After a strong score, the app offers to move you up a difficulty level. • A new animated launch. FIXES • Subscription prices show with their currency, and a purchase that fails now says so instead of staying silent. • Debates in progress are back in your history. • Bold text in messages renders properly, instead of showing asterisks. • Notification permission is no longer requested the moment you open the app. • Consistent transitions between tabs and debate screens.
