Ayo: Vocabulary Builder

You look up the same word for the third time this month. You still don't know it. Does that sound familiar?

Ayo is a personal vocabulary builder that actually makes progress — it remembers what you've looked up, tracks how well you know each word, and brings back exactly the ones you keep forgetting, so you stop repeating the same searches.

Take a photo of a book page, a sign, or a screenshot — or paste any text — and Ayo's AI reads it, detects the language, and selects the vocabulary worth learning. Add a translation instantly, and start reviewing whenever you're ready.

KEY FEATURES
• Capture vocabulary from photos or pasted text — AI detects the language and selects what is worth learning
• Five review games that schedule each word by how well you know it
• Built-in pronunciation and translation that run on the phone itself
• Your dictionary and every review game work with no connection

CAPTURE FROM REAL LIFE
Stop typing words into a search box one at a time.
• Photo or pasted text — Ayo reads it and extracts the words you need.
• Every word is saved in its dictionary form, no matter how it appeared in the text — so you get one entry per word instead of several.
• A word with multiple meanings keeps every one of them, each with its own part of speech and example sentence.
• Expressions made of several words are kept whole, not split up or discarded.
• Already know a word? Mark it as known and it will not appear again.

A REAL DICTIONARY, NOT JUST FLASHCARDS
Your vocabulary stays organized without extra work.
• Keep a separate dictionary for every language pair you are learning.
• Group words in whatever way makes sense to you — by book, chapter, trip, or topic.
• Every entry carries its translation, part of speech, and an example, in context rather than in isolation.
• Add your own notes to any entry.
• Add a word by hand whenever you like — manual entry is always free and needs no account.

FIVE GAMES THAT ADAPT TO YOU
• Flashcards — see the word, hear it read aloud, tap for the meaning, grade yourself.
• Match the Words — pair every word on the board with its translation.
• Find the Translation — multiple choice, from the word to its meaning.
• Find the Word — the same question asked in reverse.
• Word Scramble — the meaning is shown, and you spell the word back from shuffled letter tiles, with a hint available when you are stuck.

Each game schedules a word by how well you actually know it, so the ones you keep forgetting come back sooner and the ones you have mastered appear less often. Choose which groups to practice, how many words a session runs, and whether to review your least-known words, your newest ones, or whatever is due today.

HEAR IT, TRANSLATE IT
Pronunciation and translation are built into the word screen, both free and both run by your phone rather than by us — nothing leaves the device. Pronunciation uses the voices your phone already has. Translation downloads a language pack once, then works with no connection.

OFFLINE FIRST, SYNC WHEN YOU WANT
Your dictionary lives on your device, so it opens instantly and keeps working on a plane, on a train, or abroad with no data — browsing, adding words by hand, and every review game. AI capture is the one part that needs a connection. Sign in to back up your dictionary and sync it across devices, or skip the account entirely: nothing stops working without one.

PERFECT FOR
• Language learners tired of looking up the same word again and again
• Readers building vocabulary from books, articles, and subtitles
• Students who need the words to still be there on exam day
• Travelers who want to save a word the moment they see it

Ayo is a vocabulary builder you can keep for years, not a course you finish and forget. It is free to use: AI-powered capture is paid for with AI Credits, while adding a word by hand is always free and needs no account.
