About

Propaganda Detector

Features
Read full description

200 real propaganda messages, split into rounds of ten. Answer, see where you were off, and read what technique was used on you. HOW IT WORKS Every card is a short message. You are asked one question about it — is this propaganda, which technique is used, which emotion is being targeted, what is the goal. You answer, and the right option lights up green while the wrong ones turn red. Then the card opens up. WHAT EVERY CARD EXPLAINS Level — which of the four skills this card tested. Emotion — which feeling the message aims at: fear, nostalgia, pride, shame, hatred. Framing — the actual device: false dilemma, whataboutism, group demonization, appeal to authority, golden past, and 17 more. Explanation — why it works on people who are not stupid. ROUNDS AND YOUR PROFILE The deck is split into rounds of ten cards. After each one you get your accuracy for that round and a star for the deck. Your answers build a cognitive profile across four dimensions — propaganda recognition, manipulation technique, emotional trigger, and goal — so you can see which layer you read well and which one slips past you. FOUR DIFFICULTY LEVELS Cards build up gradually. Early ones are blunt. Later ones are the kind you would scroll past without a second thought. THREE LANGUAGES English, Ukrainian and Russian — interface and every card. Switch inside the app, independent of your system language. PRIVACY No account. No backend. No analytics, no tracking, no data collection of any kind. Your progress stays on your device. The app works offline. PREMIUM One-time purchase, no subscription. Unlocks the full deck across all difficulty levels, the complete cognitive profile and detailed analytics by category.
