Polyglot helps you learn several languages at the same time, all on your device and all private. Most apps make you pick one language and follow one rigid path. Polyglot is built for people who want more. Study Spanish, French, German, Japanese, Korean and more side by side, with tools that adapt to you. WHY POLYGLOT - Learn many languages at once, with a color for each one so they never blur together. - A private, on-device AI tutor builds lessons, quizzes and conversations for any topic you pick. - Smart flashcards use proven spaced repetition so you review at the perfect moment. - Fast, friendly games turn daily practice into a habit. - Speak out loud and get instant pronunciation feedback. - Translate anywhere, even offline. - Your data stays on your device. No account required. SMART FLASHCARDS Polyglot schedules every card with a modern spaced repetition engine, so you spend time on the words you are about to forget and breeze past the ones you know. Each card includes an example sentence and pronunciation, with text to speech in a single tap. AN AI TUTOR IN YOUR POCKET Type any topic, like ordering food or a job interview, and Polyglot writes a focused lesson with vocabulary, useful phrases, a short overview and a tip. Add the new words to your flashcards in one tap. Practice freely in conversation mode and get gentle, in context corrections, or take a fresh AI quiz made just for you. It runs on device, so it works without a connection and keeps your practice private. GAMES THAT MAKE IT STICK - Match Pairs: link words with their meanings. - Fill the Blank: complete the missing word. - Build the Sentence: arrange word tiles into real sentences. - Listen and Choose: train your ear. - Say It: speak the answer and get scored. Mix all of your languages in one session to get sharp at telling them apart. SEE YOUR PROGRESS Track reviews, sessions and streaks. A clean chart and calendar show your activity at a glance, and a mastery bar for each language shows how far you have come. TRANSLATE ANYWHERE Quick translation is built in and works offline.
