Avocado — Vocabulary Builder

One rewarded ad clears banners for the day. Past the daily limit you can still see what a word means, and Japanese now shows proper furigana.

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

• Find what others have built
