About this app

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 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

• 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
- 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
- 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, or regenerate on the same topic

• 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
· English — NGSL (foundation) · BSL (business) · NAWL · TSL (academic / exam)
· Japanese — Basic 500 · JLPT N3
· Chinese — HSK 1
· Korean — TOPIK Basic · Intermediate · Advanced (NIKL A/B/C frequency — great for K-pop, Hallyu, and study-abroad learners)
· Korean — TOPIK II Essentials 300 (intermediate, with examples and collocations)
· Vietnamese — Basic 500
- Share your own lists to help the community

• Six languages, every direction
- English, Korean, Japanese, Chinese, Vietnamese, Spanish
- Mix any input and meaning language (EN-KR, KR-JP, EN-ZH, VI-EN, KR-VI, ES-EN — any pair)
- Built equally for learners coming from any language to any language

• Make it yours with skins
- Classic, Dark, Y2K, Lab, Summer Sea, and more themes to choose from
- Set the mood for how you study

• Offline-first with cloud sync
