## Description

Your own wordbook, built by AI - Eppi Words  
  
Tired of building word lists and looking up meanings by hand every time?  
Eppi Words lets you start learning the moment you install it, with a ready-made starter deck,  
and from then on AI builds your wordbooks for you.  
  
Eppi Words supports English, Japanese, and Korean wordbooks.  
  
Key Features  
  
1\. A starter deck, ready the moment you install  
You do not have to add any words first. A ready-made starter deck is waiting on the first screen.  
Notification permission is only requested when it actually matters.  
  
2\. Automatic wordbook creation that AI handles for you  
Just enter a word, and AI translates it and completes the meaning, phonetic symbols, part of speech, and more.  
It can read "text in a photo" and extract up to 30 words at once,  
or build an entire word set when you simply enter a topic like "travel English."  
No more tedious word entry!  
  
3\. "Magic Card AI" that tells you everything about a word  
Even when you learn a single word, learn it deeply. Magic Card goes beyond a simple definition.  
\- Word form expansion: derived forms such as verbs, nouns, and adjectives  
\- Common expressions: idioms and collocations generated by AI  
\- Tailored examples: sentences you can use right away, with translations  
  
4\. Learning statistics that show your progress  
See how far you have come, with data.  
Eppi Words shows your study history by period and a learning timeline, scores each word  
for mastery, and lets you review only the words that are still weak.  
  
5\. Pick a voice  
Choose a voice from the list available at the time and listen to words and example sentences.  
Use it alongside your listening practice.  
  
6\. Tired of only studying? Decorate your Eppi  
Spend the XP you earn from studying on costumes and stickers, and decorate your own Eppi room.  
Study more and complete your very own Eppi!  
  
From TOEIC, TOEFL and JLPT vocabulary to hiragana and katakana, memorize by repeating flashcards.  
  
Eppi Words is for you if:  
\- You want a wordbook tailored to yourself  
\- You want to save an unfamiliar word straight from a photo or a book  
\- You want to study not just meanings but example sentences and derived forms
