Genius Flashcards: Pass Your Next Exam Studying for TOEIC, TOEFL, IELTS, JLPT, HSK, the SAT, or USMLE? Stop re-reading your notes for the 47th time. Genius Flashcards pairs AI with spaced-repetition science so you actually remember what you study — and walk into test day ready. AI-GENERATED FLASHCARDS Tell the AI what you're studying — "TOEIC Part 5 verb + preposition pairs," "IELTS academic vocabulary," "JLPT N3 kanji" — and get a polished flashcard set in seconds. No formatting, no typing. IMPORT FROM ANKI, EXCEL & CSV Coming from another app? Bring your decks with you. Import cards from Anki (.apkg), Excel (.xlsx), or CSV, pick which columns go to the front and back, and you're in — up to 5,000 cards at a time. IMPORT FROM PHOTOS & PDFS Turn your handwritten notes, lecture slides, or a textbook chapter into a clean, focused set. Snap a photo or drop a PDF — the AI reads it and builds the cards for you. PASTE A LIST Drop in a list from anywhere — notes, a spreadsheet, ChatGPT — and instantly turn it into flashcards. Just paste, and it's ready to study. SPACED REPETITION The app tracks what you know and schedules each review at the right time. Focus on weak spots, skip what you've already learned. Study less, remember more. Go in the recommended order, hardest first, or shuffled. FOLDERS FOR YOUR COURSES Organise your sets the way your classes are organised: one set per lesson, one folder per course or semester ("Biology – Semester 1", "Japanese N3", "Bar exam – Contracts"). Study a single lesson, or the whole folder in one session with cards mixed from every lesson. A set can belong to several folders. DAILY REVIEW See how many cards are due across all your sets, and review them in one session, most overdue first. Pick how many to do: 10 on a busy day, 100 before an exam. STREAKS & DAILY GOALS Build a real habit in the run-up to test day. Daily goals and smart reminders keep you consistent — and rest days don't break your streak. Track progress across iPhone, iPad, and web, with a home screen widget so you stay on top of it. STUDY GROUPS WITH LEADERBOARDS Create a group for your class, prep cohort, or study circle. Share flashcard sets and track everyone's progress on the leaderboard. Friendly competition keeps everyone showing up. FRIENDS KEEP YOU ACCOUNTABLE See your friends' streaks and study activity at a glance. When no one's studied today, you'll get a nudge. Subtle social pressure that turns into real consistency. HUNDREDS OF READY-MADE SETS Browse community sets for the big exams — TOEIC, IELTS, TOEFL, JLPT, HSK, SAT, USMLE — plus languages, science & tech, history, business, and trivia. FLEXIBLE SHARING Keep sets private, share with a link, or publish to the community. Switch any time. CLEAN, CUSTOMIZABLE DESIGN No ads, no pop-ups, no clutter. Personalize your profile and sets with custom emoji and colors.
