Polyingo turns the words you actually care about into stories, games and conversations — so they stick. Learn English, Spanish, German, French or Turkish, with the app itself in your own language. AN AI TUTOR THAT KNOWS YOUR LEVEL Chat naturally with Poly, your AI language tutor. Ask what a word means, get sentences tuned to your CEFR level, or turn the words you have saved into a short story and answer questions about it. 83 GAMES, NOT FLASHCARDS Twenty-four of them are arcade games: catch words on the beat, glide into the right meaning, rebuild a sentence one train carriage at a time. The rest cover vocabulary, writing, listening and speaking — including rounds where you say the sentence out loud and speech recognition marks it. Play with words from any CEFR level, from your own history, or filtered by tag. A DICTIONARY THAT FOLLOWS YOU Browse A1 to C2 across dictionaries, sentences, idioms and everyday routines. Pattern search finds words by shape — every four-letter word ending in "de", for example. Tap any word to hear it, translate it, tag it or save it. YOUR WORDS, REMEMBERED Every word you save keeps its audio, its translation and real examples. Tag them, filter them, and set reminders so a hand-picked word arrives even when the app is closed. LISTEN IN ANY ACCENT Text-to-speech with a choice of accents and adjustable speed, so you hear a word the way it is actually said. PRACTISE WITH PEOPLE Message other learners alongside your AI tutors. Post a word and hear how other people say it. EARN POINTS, CLIMB RANKS A 100-point daily target, Poly points for every session, and ranks to climb as you go. FREE AND PREMIUM The free plan includes monthly allowances for AI chat, translations, voice and pattern search. Premium lifts those limits and adds AI-quality translations, natural voices, games built from your saved words, every dictionary category, and reminders for any category. Setting up takes a minute: tell Polyingo the language you speak and the one you want to learn, take a two-minute level test if you like, and pick a few interests so the feed is yours.
