Grammar Fix
GRATUIT
Free
Description
Most language apps give you flashcards. HiCoCo gives you friends.
Meet a cast of AI personas — each with a distinct personality, backstory, and daily life. Chat with them in real scenarios: order coffee, navigate a job interview, catch up over a call. Every conversation is tailored to your level, quietly fixing the grammar patterns you struggle with most, without ever stopping the flow.
REAL CONVERSATIONS, REAL PROGRESS
Talk freely or pick a scenario. Your AI friends remember past conversations, adapt to your proficiency, and gently correct mistakes through natural restatement — not grammar lectures.
WORDS THAT STICK
Every word you encounter in chat gets saved automatically. Our spaced repetition system (FSRS) schedules reviews at exactly the right moment so vocabulary moves from short-term to long-term memory.
PRONUNCIATION THAT ACTUALLY IMPROVES
Speak your replies out loud. HiCoCo scores your pronunciation on the spot and shows you exactly where to improve — vowel by vowel, word by word.
YOUR DAILY LEARNING FEED
Open the app to a personalized home screen: your streak, words due for review, a grammar insight from yesterday's conversation, and a message waiting from one of your AI friends.
INSTANT DICTIONARY, ANYWHERE
Tap any word mid-conversation to see a plain-language definition in your mother tongue, real bilingual example sentences, and an option to save it to your vocabulary list. Works offline too.
BUILT FOR EAST ASIAN LEARNERS
HiCoCo is designed for Chinese, Japanese, and Korean speakers learning English or Japanese. Coco helps you start chatting immediately and guides you toward the right personas and scenarios as you go.
