The Problem

Why Learners Give Up

Traditional language learning feels like a chore. Here's what stops most people.

  • 01

    Boring Textbooks

    You memorize words from a book but can't use them in a real conversation. No context, no fun, no progress.

  • 02

    No Real Context

    Grammar drills and isolated vocabulary lists don't build natural understanding of how the language actually sounds.

  • 03

    No Speaking Practice

    Most apps teach reading and writing but leave you lost when it's time to understand or speak to a native speaker.

For Japanese learners

Built for learning Japanese

Kanji, three writing systems and pitch accent make Japanese different. Corodomo has a tool for each of them.

Furigana and romaji subtitles

Show furigana above every kanji, or switch to romaji while you are still learning kana. Turn them off once you can read on your own.

Readings and kanji in one tap

Tap any word in the subtitles to see its reading, meaning and example sentences, look up its kanji, and save it as a flashcard.

Pronunciation scoring with pitch accent

Shadow a line and AI scores your Japanese down to each mora, including pitch accent, so you know exactly which sound to fix.

Speak Japanese with CoroAI

Role-play real situations in Japanese, from ordering at a café to job interviews, and get your sentences corrected each turn.

JLPT N5–N1 mock tests

Full-length, timed mock tests with listening audio and a score breakdown by section, for every level from N5 to N1.

JFT-Basic for Specified Skilled Workers

Planning to work in Japan on a Tokutei Ginou visa? Practice for the JFT-Basic test with realistic mock exams.

What sets Corodomo apart

  • Subtitles built for learning: natural, complete sentences with timing matched to the real speech, a translation for every line, and phonetic readings — furigana for Japanese, pinyin with tones for Chinese, IPA for English and German, romanization for Korean and Thai.

  • Accurate pronunciation scoring with dedicated assessment engines (Microsoft Azure, Soniox) and word-level feedback, including Japanese pitch accent and Chinese tones — the same engines on the Free plan as on Plus and Pro.

  • AI Coaching: 1:1 shadowing coaching every day — a passage at your level, step-by-step listening, read-along and shadowing, AI scoring of your recording, and a drill of the sentences you got wrong.

  • Practice all four skills: listening (dictation, fill-in-the-blank, speed control), speaking (shadowing, CoroAI roleplay, Japanese kaiwa practice, AI speaking topics), reading (furigana and pinyin readings, articles and PDFs) and writing (AI-graded writing and translation practice).

  • Curated, reviewed content: library videos are selected and checked by the Corodomo team across podcasts, news, business, IT, culture and more, plus courses such as IT Passport, Japanese business keigo, Minna no Nihongo, HSK and TOPIK.

  • A generous Free plan: watch almost the entire library of more than 5,000 videos with bilingual subtitles, with no daily video limit.

  • Everyday AI tools are free and do not use your AI allowance: word lookup, translation, CoroAI Q&A, and AI summaries, quizzes and mind maps for library videos.

  • Learn from any source: YouTube, TikTok, your own uploads or documents, across web, iOS and Android with one account.

Frequently asked questions

01
Yes. Furigana subtitles let you read kanji from day one, and word lookup gives you readings and meanings. Start with short, slowly spoken videos and raise the difficulty over time.
02
Yes. Corodomo supports compatible YouTube videos as well as its own library. Anime is great listening practice, but its lines can be exaggerated, so mix in vlogs, podcasts or everyday videos to learn how people really talk.
03
Yes. When you practice Shadowing, AI scores each sentence and gives feedback on your pronunciation, including pitch accent. Use it to see what needs more work and to compare your results over time.
04
Yes. Corodomo offers free core learning features so you can get started. Some advanced features and AI usage limits depend on your plan.
05
Pick a short clip of 2–5 minutes and listen to it once or twice first. Then repeat each sentence right after the speaker, focusing on rhythm, intonation and pronunciation instead of translating. Repeat each part 3–5 times before moving on rather than playing the whole video straight through.
06
Play the video one sentence at a time and type what you hear before you look at the translation. Replay difficult sentences as often as you need and keep a steady pace.
07
CoroAI lets you practice speaking in real situations. Conversation mode feels like a real dialogue; Learning mode corrects you each turn like a teacher. Topics range from daily chat and ordering food to job interviews.
08
You can practice everyday conversation, ordering food, shopping, travel, phone calls, workplace talk, presentations, study-abroad situations, and job interviews — or create a custom topic for any scenario you need.
09
Short daily sessions of 15–30 minutes work better than occasional long ones. Keeping the habit going matters more than how long each session is.
010
Use flashcards with spaced repetition. Put each new word into an example sentence and review it after 1, 3 and 7 days. Corodomo’s flashcards and quizzes are built for exactly this.
011
We accept international credit and debit cards (Visa, Mastercard…), PayPal, and bank transfer (VND or JPY). You choose your method at checkout; if you have any questions, feel free to contact our support team.
