Got an opinion? Prove it. Topic Hero turns hot takes into real debates. Pick a side on today's most talked-about topics, make your case, and let an impartial AI judge decide who argued it better — in seconds. HOW IT WORKS Swipe a topic to agree or disagree, and you're matched with someone who took the opposite side. Trade arguments in the chat, then get a verdict that names a winner and explains exactly why. Win or lose, you'll see how your reasoning stacked up. THREE WAYS TO PLAY - Match with debaters everywhere — swipe a topic and go head-to-head with a real person who disagrees. - Challenge your friends — call someone out on a specific take; they automatically argue the other side. - Hot-seat, in the same room — press and hold any topic to debate a friend on one phone. Timed turns, a coin flip to start, film-countdown beeps, and an instant spoken-word verdict. Just talk — the app listens and judges. RECORD IT. SHARE IT. Turn a debate into a video worth sharing. Topic Hero films you both with the topic, turns and timers on screen — and the AI verdict drops live on camera, so the reaction is part of the clip. Save it to your gallery or share straight to TikTok, Instagram and WhatsApp. Everything — recording, judging and video processing — happens on your phone. Your footage never leaves the device. A JUDGE YOU CAN TRUST Verdicts land in about a second, and every result comes with an Integrity check: did each debater stay on topic, and did they actually argue their own side? You'll see both as clear percentages — and if someone argued the wrong side by mistake, the judge quotes the exact lines and explains how it counted. SEE WHAT THE WORLD IS ARGUING ABOUT Open straight into Trending — the hottest topics from every category, gathered in one place and shuffled fresh every time. From sport and science to entertainment and the news, there's always something worth taking a side on.
