Remember what you learn. KnowUp is an AI-powered flashcard app that helps you remember more with less effort. Using spaced repetition, it reminds you to review at the right time—before you're likely to forget. Whether you're learning vocabulary, preparing for exams, or studying for school, KnowUp helps you build knowledge that lasts. ■Review at the Right Time Forgetting is a natural part of learning. Research suggests that much of what we learn fades quickly without review. KnowUp uses the proven SM-2 spaced repetition algorithm to schedule reviews based on your learning performance. Reviewing at the right intervals helps strengthen long-term memory while reducing unnecessary repetition. ■Create Flashcards with AI Creating flashcards shouldn't take longer than studying. Simply take a photo of your textbook, class handout, or notes. AI automatically extracts questions and creates flashcards for you. Review the generated cards, make any edits you want, and start learning in minutes. ■ AI explains answers clearly Instead of just memorizing the answer, you can learn while understanding why it is correct. For example sentences and questions, AI provides easy-to-understand explanations of the content and expressions, helping you deepen understanding as you review. ■ Import Anki and Quizlet content in bulk You can continue using the flashcards and study content you already have. Import Anki and Quizlet content in bulk and use it directly for review in KnowUp. It reduces the need to recreate cards from scratch, so you can start studying right away. ■Stay Motivated Every Day Learning is easier when you can see your progress. • Earn XP every time you review • Level up as you continue learning • Build daily study streaks • Track your retention and study habits with detailed statistics ■Learn Together Studying with friends makes it easier to stay consistent.
