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 doesnβt 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.
