Description
Every language in your hand, Eppi Words
Tired of making word lists and looking up meanings by hand every time?
Eppi Words completely reinvents the way you learn vocabulary.
Experience the wonder of AI building your wordbooks automatically and giving you complete, detailed information.
It supports languages from all over the world, including English, Japanese, Korean, Chinese, Spanish, French, German, Indonesian, Italian, Portuguese, and Vietnamese!
Key Features
1. Automatic wordbook creation that AI handles for you
Just enter a word, and AI translates it and automatically completes the meaning, phonetic symbols, part of speech, and more.
It can read "text in a photo" and instantly extract 30 words,
or build an entire word set when you simply enter a topic like "travel English."
No more tedious word entry!
2. "Magic Card AI" that tells you everything about a word
Even when you learn a single word, learn it deeply! The Magic Card feature goes far beyond a simple definition and uncovers everything about a word.
- Word form expansion: Various derived forms such as verbs, nouns, and adjectives
- Common expressions: Idioms and phrases that native speakers actually use together
- Custom examples: Perfect example sentences and translations you can use right away in real life
3. Detailed learning stats that let you see your daily progress
Check exactly how much you have grown with real data.
See your vocabulary comprehension and overall proficiency, plus a timeline showing which wordbooks you studied each day and how much.
Systematically manage words you have fully memorized, words that need review, and words still in progress.
4. A variety of voices that sound natural to your ears
No more stiff robotic sounds!
Choose the voice you want from a range of accents such as American, British, and Australian English, along with male and female voice options.
Practice accurate listening with natural pronunciation.
5. A rich wordbook library suggested by AI
Not sure which words to start with?
Jump right into countless ready-made wordbooks organized by category, including beginner level, practical conversation, exam prep, and business.
The AI learning center smartly recommends words that match your level.
6. Bored of just studying? Try building a sticker book
Use the XP you earn while studying to buy your favorite stickers in the sticker book and decorate it.
Learn more words and complete your very own sticker book!
Eppi Words is recommended for people who:
- Want their own personalized wordbook
- Want to instantly save unfamiliar words they come across in photos or books
