State a belief. Get the single most compelling, intellectually honest argument against it.
Contria does one thing: you state a belief, and it gives you the single most compelling, intellectually honest argument against it.
Not a debate-club rebuttal. Not a strawman. A steelman of the opposing view — the case a brilliant, honest opponent would actually make. One belief in, one counterargument out, revealed all at once like a verdict.
CHOOSE YOUR INTENSITY
• Mild — gentle. Acknowledges the merit in your view, then raises one strong doubt.
• Uncomfortable — concedes your point has real merit, then dismantles it.
• Brutal — the tightest possible case against, argued with full conviction, no hedging.
WHY
Most of what you read agrees with you. Contria is the antidote: a tool for stress-testing what you're sure about. The point isn't to change your mind — it's to make you slightly less certain about everything, and clearer about why you believe what you still believe.
• Keep a history of every belief you've stress-tested
• Rate arguments, so the ones you see keep getting sharper
• Browse the public gallery of beliefs others have dared to test — and share your own
• A new belief to challenge every day, with an optional daily reminder
• Speak your belief instead of typing it, or share text to Contria from any app
• Plus scores your pushback: did you actually answer the argument?
• In English, Swedish and German — arguments arrive in your language
Mild intensity is free. Contria Plus unlocks the rest, as an auto-renewable subscription: Contria Plus Monthly (1 month) or Contria Plus Annual (1 year). Payment is charged to your Apple Account at confirmation of purchase, and the subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.
