Show HN: Kachika – "Learning Japanese Through Life"

5 points by xcc3641 3 days ago

I'm both a Japanese learner and an indie developer. Throughout my journey of learning Japanese (currently living in Japan), I've deeply felt the challenge of memorizing words — learning them only to forget, wanting to speak but finding myself tongue-tied.

Why I Made This As someone who relies heavily on visual memory, I understand the power of turning abstract concepts into visual forms. You know that feeling when you're walking around and spot something interesting — maybe a beautiful seasonal poster, a curious shop name, or even just a package design that catches your eye? Those little moments of curiosity that make you think "I wish I could remember these words!"... That was exactly my experience

This experience inspired a simple yet powerful idea: "Learn Japanese through life, live with Japanese" — and that became the heart and soul of this app: Kachika (カチカ).

Turn Your Daily Discoveries into Learning Moments Kachika helps you learn Japanese naturally through your everyday life:

Capture What You See Just snap a photo of anything interesting in your daily life

Instant Learning Words are detected automatically with native pronunciation

Your Personal Collection Build vocabulary that matters to you, all stored privately on device

Fun fact about the name "Kachika" (カチカ):

カチッ (the sound of taking a photo)

勝ち (kachi - victory/success)

か (ka - that soft Japanese particle that makes everything sound nicer!)

I Need Your Help! I'm looking for fellow Japanese learners who want to make learning more natural and meaningful. What features would help you capture and remember your daily Japanese encounters?

I hope this app can help fellow learners who share the same struggles, making Japanese learning a natural part of our daily lives!

Would love to hear your thoughts and suggestions from:

People studying Japanese at any level

Visual learners who prefer real-world context

Anyone who wants to learn Japanese through their daily experiences

Let's make Japanese learning a natural part of our everyday adventures! ありがとうございます！
