Lazidi is a flashcard app for lazy learners: open, swipe, remember. One word per card, a hand-drawn illustration and a native voice — swipe up whenever you want the full story. FOUR LANGUAGES, THE RIGHT LEVEL • English, CEFR A1 → C2, with US and UK pronunciation and a World deck • Chinese, HSK 1 → 7–9, with radicals, grammar and Sino-Vietnamese readings • Japanese, JLPT N5 → N1, with the kana charts, kanji cards and grammar • Vietnamese, Level 1 → 6 More than 61,000 study cards and a lookup dictionary of over 263,000 entries. Filter by level, topic, part of speech and purpose (exams, travel, food…). ONE CARD, ALL THE WAY DOWN • A short meaning up front, the full definition when you swipe up • Bilingual example sentences — tap the speaker to hear the whole sentence • Memory tips, collocations, near-synonyms and easily confused words • Chinese characters broken into components, with historical scripts from oracle bone to cursive • Japanese furigana, romaji, pitch accent and transitive–intransitive verb pairs • Draw a character in the search box when you can't read it WRITING AND CALLIGRAPHY Press and hold a character to practise its stroke order, graded stroke by stroke. Write with a ballpoint, a fountain pen or a brush; the Calligraphy desk adds paper formats, tracing guides, a red seal and saves your work as an image. LEARN BY PLAYING Up to 14 review games built on the deck you're studying: true/false swipes, multiple choice, fill in the blank, listen and write, matching, flip cards, tones, dictation… Words you're about to forget come back at the right time, and a "Remember this?" card pops into your deck. Daily goals, challenges, 186 achievements and Game Center leaderboards. ILLUSTRATED READINGS More than 350 stories, fables, nursery rhymes, Tang poems, couplets, haiku and classical texts across all four languages, with illustrations, narration and paragraph-by-paragraph translation. Tap any word to see its meaning. New readings arrive without an app update. YOUR OWN WORD LISTS Paste a paragraph, snap a page or pick a photo: Lazidi picks out the words it has cards for and makes a deck. Put Scan Words on your Lock Screen or in Control Center, or ask Siri. LEARN TOGETHER Put two iPhones or iPads side by side to connect — no account needed: Study together, Teach (the student's device follows the teacher's) or Duel to see who's faster. Kids mode with big pictures, big text and a big speaker button. THE CU LI ASSISTANT On devices with Apple Intelligence: ask cu li about a word, get more example sentences, have your sentences corrected or role-play a conversation. WORKS OFFLINE Download a language pack once: cards, pictures and pronunciation live on your device. Example audio and readings download when you're online.
