Chenjin Mandarin-Learn Chinese

Chenjin (沉浸, "immersion") is for learners who want to live in Chinese, not just drill it. Read real stories at your level, tap anything you don't know, and let the app quietly turn your reading into vocabulary, listening, and pronunciation practice.

It's built for the intermediate plateau (HSK 3-7), and friendly enough to start earlier.

READ AT YOUR LEVEL
• Graded stories and full books, organized by HSK level
• Tap any word for an instant popup: meaning, pinyin, stroke order, character breakdown, and example sentences
• Pinyin above characters, on hover, or off. Simplified or traditional. Your choice.
• Sentence-by-sentence audio and translations when you need them

REMEMBER WHAT YOU READ
• Save any word or sentence as a flashcard with one tap
• A modern spaced-repetition system (FSRS) schedules reviews right before you'd forget
• Daily review reminders keep your streak alive
• A vocabulary heatmap shows exactly which HSK 1-7 words you know

TRAIN YOUR EARS AND TONES
• Dictation practice: listen to a sentence, then type it or speak it back
• Voice answers are scored syllable by syllable
• Tone Coach shows your pitch curve next to a native speaker's, so you can see exactly where a tone goes wrong
• Native-quality audio for every word and sentence

POINT YOUR CAMERA AT CHINESE
• The OCR scanner reads printed Chinese around you: menus, signs, packaging
• Recognition runs on your device. Tap any recognized word to look it up.
