LEKAT

LEKAT helps you actually remember what you study — by making you explain it, not just re-read it. Based on the proven Feynman technique and active-recall research, LEKAT turns any material into a loop that sticks: add a topic, take a quick quiz, then explain it back in your own words out loud. LEKAT transcribes your explanation on-device and grades how well you understood it — so you find the gaps before an exam does. HOW IT WORKS 1. Add a topic — paste text or a link, import a PDF or audio file, snap a photo, or scan a document. 2. Take an AI-generated quiz tuned to your chosen difficulty. 3. Record yourself explaining the topic aloud. Speaking your understanding is what cements it in long-term memory. 4. Get an instant score, strengths, and the concepts you missed — then review and try again. FEATURES • Explain-and-grade: record your explanation, get an AI score with strengths and missed concepts • Smart quizzes: multiple choice, true/false, fill-in-the-blank, and short answer • Weak-spot quizzes that target exactly what you keep getting wrong • Adaptive difficulty that grows with you • Spaced-repetition review scheduler so topics resurface right before you'd forget them • Flashcards auto-built from your material • Auto-summary and key points for every topic • Import from anywhere: text, links, PDFs, audio/video, photos, and the document scanner • Insights dashboard, streaks, goals, and badges to keep you going • Daily study reminders PRIVACY • No account or sign-in required. • Your audio recordings never leave your device — transcription happens on-device. • Text you add is sent to OpenAI to generate quizzes and grade explanations. Study less by re-reading. Learn more by explaining. That's LEKAT.
