STOP PASSIVE STUDYING. START MASTERING. You think you know your subject? Prove it. KnowIt is the first app that combines the Feynman Technique with advanced AI to turn your voice into the ultimate learning tool. Most students re-read notes endlessly. That’s inefficient. The only way to truly learn is to teach. KnowIt listens to you, grades your logic, and prepares your reviews automatically. HOW IT WORKS: Quick Session (Tap & Talk) No folders, no friction. Just open the app, hit the big red button, and explain a concept (Law, Code, Med, History...) as if teaching a toddler. AI Grading & "Roast" Our AI doesn’t just transcribe; it audits your knowledge. The Score: Get a raw understanding score (0-100). The Feedback: The AI identifies logic gaps, hesitation, and missing key facts. It tells you exactly what you don't know yet. Instant Flashcards Stop wasting hours typing cards. KnowIt automatically generates flashcards specifically targeting the gaps found in your explanation. Spaced Repetition (SRS) Review your generated cards with a smart algorithm (Anki-style). Swipe Right if you know it, Swipe Left if you forgot. We handle the scheduling to ensure long-term retention. WHY KNOWIT? Zero Friction: Designed for flow. Capture ideas while walking or commuting. The AI auto-titles and categorizes your sessions. Active Recall: Forces you to structure your thoughts, not just memorize them. Gamified Growth: Keep your Streak alive and watch your "Explanation Score" improve over time. Whether you are a med student, a developer learning a new stack, or a lifelong learner, KnowIt is the relentless tutor in your pocket. Download now and test your first explanation.
