About this app

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

Ayo is a personal dictionary 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 translating never turns into a loop.

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

CAPTURE FROM REAL LIFE

• Photo or pasted text — Ayo reads it and extracts the words that matter.
• Words are reduced to their dictionary form, so "running," "ran," and "runs" all become "run."
• A word with multiple meanings keeps every one of them, each with its own part of speech and example sentence.
• Already know a word? Mark it known and it won't show up again.

A REAL DICTIONARY, NOT A DECK OF CARDS

Organize your vocabulary into dictionaries by language pair, and group words however makes sense to you. Every word carries its translation, part of speech, and an example — in context, not just looked up in isolation.

REVIEW THAT ADAPTS TO YOU

Four games — Flashcards, Match the Words, Find the Translation, and Find the Word — schedule each word based on how well you actually know it, so the words you keep forgetting come back sooner and the ones you've mastered stay out of the way.

HEAR IT, TRANSLATE IT

Built-in pronunciation and on-device translation, right from the word screen — free, offline, and private.

WORKS OFFLINE, SYNCS WHEN YOU WANT

Your dictionary lives on your device first. Sign in to back it up and sync across devices — everything keeps working even if you don't.

PERFECT FOR

• Language learners tired of relooking-up words they've "already learned"
• Anyone building vocabulary from books, articles, or shows
• Travelers and readers who want to capture a word the moment they meet it

Ayo is free to use. AI-powered capture is metered with AI Credits; typing a word in yourself is always free, no account needed.
