Learning languages is actually pretty simple: if you consume content you enjoy, and you understand that content, you will make progress. Period. Migaku (and its Chrome browser extension) enables you to do that: 1. Our courses take you from zero to 80% comprehension in ~6 months (10 cards/day) 2. We make text interactive: click words in your phone's YouTube subtitles to see what they mean 3. We let you make media-rich flashcards out of those words with one click 4. We make personalized study sessions out of the flashcards you create 5. Repeat! Whether you're learning Japanese, Mandarin, Korean, Spanish, Italian, German, Cantonese, Portuguese, English, French or Vietnamese, Migaku equips you with the tools you need to make real progress. Migaku requires a paid subscription to access its courses, features, and AI tools. Migaku – AI Language Learning Tool ■ How languages are really learned: If you want to watch movies in other languages, then you need to learn languages with movies. If you want to read books in other languages, then you need to learn languages by reading. As you spend more time doing the things you enjoy doing in the language you're learning, you'll build the unique skills you need to more easily do those things. Unfortunately, it's difficult to read books and watch movies in another language as a beginner. And that's where Migaku comes in ■ Data-driven courses for beginners The problem with most apps and textbooks is that they teach you what someone else thinks language learners need to know, and those things may not reflect what you actually need to learn to do the things that are important to you. This matters because not all words are used equally often: while a college-educated native speaker knows ~30,000 words, you only need to know ~1,500 words to recognize 80% of the words in modern media. Our flashcard-based courses teach you these ~1,500 words—the ones that are useful to everyone, no matter their goals—plus a few hundred basic grammar points. What makes our courses special is that every "next" flashcard contains only one new word, making Migaku's learning curve super smooth. You're always learning something new, but never overwhelmed. It's a fluent language learning approach. Migaku courses are currently available for Japanese, Mandarin, and Korean. ■ Turn subtitles and text into interactive language learning opportunities Migaku makes texts interactive: just click on words to see what they mean. You can also hear audio recordings from native speakers, reference images of the term, check example sentences, get an AI explanation of what the word means in context, have AI break sentences down for you word-by-word, or see a translation of the sentence that your word appears in. Basically, Migaku lets you consume content in another language as if you knew as many words as a native speaker. Our mobile app supports YouTube, manually pasted content, and physical content like books or street signs. Our Chrome extension supports web pages and several popular streaming websites. ■ Create custom study cards or import language flashcards Find a useful looking word while consuming content? Turn it into a high-quality flashcard with one button, and Migaku's spaced repetition language practice algorithm will create personalized study sessions for you. You'll be nudged to review these flashcards periodically, ensuring you remember them. Decks designed for the Anki flashcard app can be converted for use with Migaku, too. ■ Study anywhere, even offline Migaku's courses and any flashcards you make are available offline and automatically sync between all of your devices. ■ Learn multiple languages at once A single Migaku subscription gives you access to all of Migaku's languages and lets you use all of Migaku's features and AI language learning tools as much as you want. - - - Immerse → enjoy → improve
