About this app

【What is Kotoba Stock?】 Kotoba Stock is a personalized dictionary app where you can continuously add new words you encounter in everyday life and technical terms you're learning.

More than just a notepad, it aims to solidify (stockpile) recorded words as "solid knowledge" by organizing them and reviewing them regularly. The more you use it, the more your own unique dictionary grows!

【Main Features】 📝 Quick and Easy Word Registration: Register new words the moment you encounter them. You can record not only the meaning of the word, but also example sentences you create and your own interpretations (notes).

📚 Sense of Accomplishment as Knowledge Accumulates: The words you register accumulate in your list. The sense of accomplishment from learning so many words boosts your learning motivation.

🔄 Review Function to "Never Forget": Reviewing previously registered words strongly supports memory retention. Eliminate the feeling of "What was that word I looked up back then?"

🔍 Quick Search Search for keywords from your saved words, relying on titles and notes. Quickly retrieve knowledge later.

【Recommended for people who:】 ・Often look up unfamiliar words while reading or watching the news ・Want to create their own vocabulary list for qualification exams or language learning ・Want to compile their own list of work-related or programming terms ・Want to save daily insights and memorable quotes

Why not experience the joy of building knowledge with Kotoba Stock? Let's start saving today's "interesting words"!
Build your knowledge! Quickly jot down words you hear and see, and review them thoroughly! This is "Kotoba Stock," your own personalized dictionary and vocabulary app.
