Introduction to Corodomo: Learn Languages with Real Videos

Corodomo is a platform for learning languages through real videos. Instead of memorizing isolated word lists, you learn from interviews, vlogs, news clips, podcasts and dramas, with tools that help you understand every sentence, say it out loud and remember the words you meet.

What Is Corodomo?

Corodomo currently supports six languages: Japanese, English, Chinese, Korean, German and Thai. You can use it on the web and in the iOS and Android apps. The library holds more than 5,000 hand-picked videos, each with bilingual subtitles split into clean sentences and a pronunciation guide: furigana for Japanese, pinyin for Chinese, IPA for English and romanization for Korean and Thai.

Key Features of Corodomo

• Sentence-by-sentence listening: Play, pause and repeat any line of a video until you catch every word.

• Shadowing with AI feedback: Repeat after the speaker and get a detailed pronunciation score down to each word. For Japanese, the feedback also covers pitch accent.

• Dictation: Type what you hear to train your ear and your spelling at the same time.

• Tap-to-translate and flashcards: Tap any word in the subtitles to see its meaning, then save it as a flashcard that comes back for review on a spaced repetition schedule.

• Summaries, quizzes and mind maps: Check that you understood the whole video, not just single lines.

• CoroAI: Ask the AI assistant about grammar, nuance or usage in any sentence you are watching.

Mock Exams, AI Coaching and Studio

• Online mock exams: Practice for the JLPT (N5 to N1), the HSK (levels 1 to 6 in the HSK 3.0 format) and the TOEIC Listening & Reading test. Taking a test and seeing your score is free; detailed explanations and Ask Coro AI are part of Plus and Pro.

• AI Coaching: Guided one-on-one shadowing practice for Plus and Pro members. Learn more on the AI Coaching page.

• Studio: Create your own lessons from a prompt, a document or a link.
