Migaku is a powerful language-learning platform anchored by a Chrome extension that transforms any website into effective study material. It begins by helping learners build a strong foundation through beginner courses that cover the most common vocabulary and grammar patterns, accounting for over 80% of everyday language. Once foundational knowledge is established, users can interact with native-content by clicking words in text or subtitles to instantly receive definitions, pronunciations, images, AI-generated explanations, and context, all of which can be captured in richly detailed flashcards. These flashcards include the target word, its original context, audio, screenshots, definitions, and AI explanations. It employs a spaced-repetition system to help learners retain what they’ve studied, while also providing personalized tools such as comprehension scoring, monolingual dictionaries, and customizable learning options.
