Debate Coach

You think of the perfect line three hours later. Debate Coach gives it to you now. Say what the argument is about and what the other person said, and it writes back messages you can send word for word — with a receipt underneath, so you are not asserting something you cannot back. TWO WAYS TO USE IT Coach — for the argument you are actually having. Paste what they sent. Get replies that answer it, in your voice, ready to send. Spar — for the one you are about to have. Pick a topic, pick your side, and the app takes the other side and tries to beat you. Good practice for the real thing, or just for the sport of it. WHAT MAKES IT DIFFERENT A receipt under every message. Each reply shows what it is leaning on, so you can check it before you send it rather than after. It writes what you would write. First person, plain text, no markdown, no "well, actually" — the message is the message. Spell it your way and it follows your spelling. Three tones. Friendly concedes their fair points before countering. Sharp lands the point cleanly, no hedging. Savage names the hole in their reasoning and is funny at that reasoning's expense — the argument, never the person. It knows who is receiving it. A housemate is not your boss, and neither is a stranger replying to you online. Say who you are up against and what winning would look like, and the reply changes shape. It keeps going. They answer back, so do you. The whole exchange stays in one thread you can come back to. 31 LANGUAGES The interface is translated into 31 languages, and replies are written in the language you are arguing in — because the message is the product, and a message you cannot send is no use to you. PRIVATE BY DEFAULT No account and no sign-in. Your saved arguments stay on your phone. No analytics, no ads, no tracking, and the app asks for no system permissions at all. FAIR WARNING Replies are written by AI. They can be wrong, including the facts offered as support, and they are not legal, medical, financial or professional advice. Check anything you plan to present as fact before you send it. The app argues with arguments. It will not write harassment or threats, and it will not go after a person or a group of people — only the reasoning. PREMIUM Free to try. Premium unlocks unlimited arguments and replies, every tone including Savage, and a receipt under every message. Monthly or annual, auto-renewing until you cancel, with no free trial.
