ZemoMemo: Learn fast. Remember forever. ZemoMemo helps you master massive amounts of information without forgetting old concepts. We blend the speed of cramming with the retention of spaced repetition, powered by the research-grade FSRS-6 model, so you can learn fast *and* remember for the long term. WHO IT’S FOR * High school & AP students * College & grad school (incl. pre-med/med) * Language learners * Professional certifications (e.g., CompTIA A+), and lifelong learners WHY ZEMOMEMO * Start learning in under 1 minute * Achieve same-day mastery with guided Learn mode * “Stickiness” score tracks how long a card will stay in your memory * Smart, less than 5-minute Refresh sessions resurface cards right before you forget * Gamified metrics & activities keep you motivated * Scientific FSRS-6 scheduling for proven retention STUDY MODES * Read - build familiarity at your pace * Learn - active recall with confidence marking * Refresh - quick, targeted reviews to boost “stickiness” * Test - check mastery when it counts * Match - mix it up for variety and speed BRING YOUR CONTENT * Import from Quizlet * Import from Anki * Create with AI: generate decks and courses from a prompt, notes, or a PDF textbook * Specialized plugins for use cases like Japanese language learning (No need to start from scratch. Bring your existing material.) DECK TYPES • Zemodeck: Simple list of flashcards; perfect for smaller sets and quick sprints (Quizlet users: Learn mode is free). • Superzemo: A collection of Zemodecks for big topics (AP courses, college classes, med school) that splits massive decks into digestible bites - so you never forget old info while learning new material. HOW IT WORKS 1. Learn Mode gives each card an initial stickiness score (how many days it’s likely to stay in memory). 2. When you’re about to forget, ZemoMemo prompts a quick Refresh session (less than 5 minutes). 3. Correct refreshes raise the stickiness score. 4. Higher stickiness = longer retention and better performance over time. ZEMOCOURSES LIBRARY Ready-made, expert-created courses to learn faster: * AP: Chemistry, Biology, World History, Psychology, Economics & more * Languages: Spanish, Yorùbá, Telugu, French & more * Misc: World Capitals, professional certifications, and other niche topics WHAT LEARNERS SAY “ZemoMemo is tailored to the needs of all students… and provides the most important part of academic success: structure.” - Hailey, Purdue University “I’ll be using this for senior year with 3 new APs… You’re awesome!” - Savannah, Morrison Academy (Taichung, Taiwan) “This product is a hidden gem… It’s been helping with CompTIA A+ 1102 - we’re two new users!” - marstakeover (Reddit) WHY IT’S DIFFERENT Traditional flashcard apps make you pick: fast cramming *or* slow spaced repetition. ZemoMemo gives you both: rapid first-pass learning with science-backed retention. So you can move quickly without losing what you’ve learned. GET STARTED * Create your first deck in a minute * Import from Quizlet or Anki * Or try a sample course and see the difference ZemoMemo - best of both worlds: learn fast, remember forever.
