Avocado — Vocabulary Builder

The word list you want. The word list you've been looking for. And the cleanest way to memorize either.

Avocado is a personal vocabulary learning tool for six languages — English, Korean, Japanese, Chinese, Vietnamese, and Spanish — built to make every spare minute count. Whatever your native language, whatever you're learning, mix and match any direction.

• Four study modes
- Flashcards: one card at a time, the way you remember best
- Quiz: multiple choice and short answer
- Example sentences: learn words in context
- Autoplay & shadowing: listen and speak along for pronunciation and listening practice

• A daily learning flow that fits you
- Set a daily target and Avocado distributes the words for you
- Clear graphs of progress and mastery
- Words you've nailed and words that trip you up are tracked separately
- Star a word or revisit only the ones you got wrong

• Gentle Review — right before you forget (NEW)
- Memorized words quietly resurface right when you're about to forget them
- Words you know well come back rarely; ones you keep missing come back sooner — spaced repetition that stays kind
- Each day's review is capped, so nothing piles up even if you skip a few days
- A soft reminder once a day, only when there's something to review

• Streaks & stats
- Day streak, calendar, and words learned — all in "My Learning"
- Watch today's, this week's, and total memorized words add up
- Share your progress as an image

• Add words by photo or spreadsheet
- Scan a photo and pull in all the words at once
- Paste in or import a CSV file as-is
- Bulk paste: drop a line-separated list and it just works
- Voice input and manual entry also supported

• AI word generation & auto-analysis
- Type a topic and AI builds an entire list for you
e.g. "Renting an apartment in the US", "Ordering at a cafe", "TOEIC verbs"
- Add a single word and AI auto-fills pronunciation, meaning, examples, and synonyms
- Choose language pair, difficulty, and word count
- Keep only the words you like, regenerate fresh ones on the same topic for more

• Find what others have built
- Browse word lists shared by other learners and import the ones you love
- A rich set of official curated lists, ready to study
