CogniSift turns critical thinking into a small, practical daily habit. Start with one short real-life challenge each day. Choose the clearest interpretation, then learn how a bias, argument flaw, evidence problem, or decision trap shaped the situation. Explore a searchable library of reasoning patterns, save useful concepts, and train with focused five-question rounds. When you miss a pattern, CogniSift automatically adds it to your Review Queue so you know exactly what to revisit. Track your streak, accuracy, solved patterns, and progress across categories without creating an account. Everything works offline and your learning data stays on your device.
