Master Japanese in Every Browse
Forget easily? It’s lack of context. Read smoothly with intelligently matched i+1 content, and acquire vocabulary naturally
The Most Efficient Way to Learn Japanese Online
💡 It's that simple:Just hover to get translation and pronunciation. Reading remains smooth; learning happens subconsciously.
Why do you forget words after memorizing them?
Because of the lack of Context. We capture i+1 level content for you, allowing you to naturally absorb new words while understanding the text.
Comprehensible Input
Stop rote memorization.True language acquisition only happens when youunderstand the message.
We capture content that combines i(your current level) + 1(a slight challenge).
Easy enough to read, but challenging enough to learn.
Let your brain naturally "acquire" Japanese through reading and understanding, rather than painfully "memorizing" it.
"We acquire language when we understand messages."
— Stephen Krashen, Linguist

AI-Driven Scientific Method
Rigid Dictionaries: Local database matching, fails at polysemy and context.
AI Context Awareness: Cloud LLM analyzes context in real-time, explaining like a teacher.
Look up everything: Screen full of unknown words, exhausting to check, killing interest.
Level Matching: Hides too simple words, highlights only "i+1" words valuable for growth.
Fully Offline: Safe but features are basic, cannot handle complex context.
Secure Cloud: Data is encrypted for AI parsing only, instantly deleted, never stored.
Pop-ups & Ads: Cluttered interface often blocking the view.
Ultimate Clean: No distractions. Give the screen space back to reading.
Frequent Interruptions: Copying words to check in another app breaks your thought process.
Immersive Flow: Meaning appears on hover. Eyes stay on the line, 100% focus.
Mute Japanese: Can read textbook Japanese but fail to understand authentic expressions.
Language Intuition: Skip the "translation" process and build direct Japanese thinking circuits.
🎯Conclusion: With the right method, 3 months beats 3 years.
