Why Polylingo
One glossary that speaks all of your languages
Most apps teach a language in English. Polylingo explains any language in up to four languages of your choice — the ones you actually think in.
🧠
AI-written, learner-first
Every word becomes a rich entry: meaning, register, usage notes and natural example sentences — generated for you in seconds.
🌏
Any language pair
Learning Japanese, explained in Malay and Chinese? Thai explained in English and Arabic? You choose from 50+ languages — or type your own.
☁️
Yours, everywhere
Sign in on your phone, tablet or computer and your entire glossary is there — synced automatically to your account.
Inside the app
A look at your future glossary
Real screens from Polylingo — pick your languages, look up a word, and untangle the confusing ones.
1
Learn one language, explained in up to four
Pick the language you're learning, then choose up to 4 languages for explanations and translations — the ones you actually think in. Korean explained in English and Spanish? Thai in Malay and Chinese? It's entirely your call, from a list of 50+ languages.
2
Every word comes alive with context
Each entry gives you a clear explanation of the word — meaning, part of speech and usage notes — plus several natural example sentences that show exactly how it's used in real life. Tap any word in a sentence to look it up instantly.
3
Confused by similar words? Compare them
When several words seem to mean the same thing, the Compare feature explains the real differences in meaning and usage — in simple language, with a side-by-side table — so you always know which word fits the occasion.
