Snap a photo, open a PDF or play a video, and Flash AI turns the words you don't know into flashcards with meaning, IPA, examples and pictures. Then make them stick with games, spaced repetition and your Home Screen. CREATE CARDS IN SECONDS • Photos & PDFs: tap any word on a photo, a textbook page or a PDF to make a card. • E-books: read EPUB, MOBI, FB2 and CBZ books and save new words as you read. • Videos: watch with dual subtitles, tap a word to save it, and practise listening, reading, writing and speaking. • News & stories: read real articles in the built-in browser and turn any word into a card. • Paste a passage and AI picks out the vocabulary, or import cards from CSV, Excel and text files. LEARN WITH WHAT YOU LOVE • 80+ ready-made collections in 10 languages, including IELTS, SAT, JLPT N5–N1, HSK and TOPIK. • AI Collection Wizard: pick up to 3 topics and get a deck built for your level. • Passage Practice: AI writes a short passage from your own words, then you fill in the missing words, rebuild sentences and listen with meanings. • Furigana, Pinyin and Korean romanization appear over Japanese, Chinese and Korean text. REMEMBER FOR GOOD • Spaced repetition with 5 memory levels brings each word back just before you'd forget it. • 10 vocabulary games, such as Whack a Word, Meteor Defense and Word Garden, plus flashcards, typing and handwriting practice. • Natural voices read every word, example and sentence aloud. • Home Screen widgets show a card or your streak: flip it, hear it or mark it learned without opening the app. • Streaks, daily goals, missions and leaderboards keep the habit going.
