Have a 500-day streak but still freeze when trying to talk to a local? Stop repeating 'the apple is red' for 300 days. Practice real, high-stress conversations so you don't freeze when you land in Europe. Whether you’re ordering food abroad, preparing for an interview, or connecting with family, practice what you want to say before the moment arrives. Build the confidence to actually use a new language with Parlo by Mamu. Practice realistic AI conversations, explore guided lessons, and work on pronunciation all at your own pace, without the pressure of getting everything right. TURN WHAT YOU LEARN INTO WHAT YOU CAN SAY Move beyond recognizing words to using them in conversation. Parlo brings speaking, listening, vocabulary, and grammar together so you can practice expressing your own thoughts. Start with practical phrases or challenge yourself with deeper discussions. Choose topics you care about and adjust the conversation’s level and formality to suit your goals. MORE THAN GAMES AND VOCABULARY You can keep a streak, match words, memorize vocabulary, and still struggle when someone asks you a question. Many language apps teach individual pieces through games and isolated exercises. Parlo helps you put those pieces together: finding the words, forming sentences, understanding what you hear, and responding in conversation. Practice speaking, listening, grammar, vocabulary, and pronunciation together through guided lessons and realistic AI conversations. Put what you’ve learned to use, with support when you need it. Because the goal isn’t just to finish another exercise. It’s to feel ready for your next real conversation. PRACTICE REAL-LIFE CONVERSATIONS Build confidence for everyday situations with AI roleplay: • Travel, study abroad, and moving overseas • Restaurants, cafés, and ordering food • Work, school, and job interviews • Dating and meeting new people • Conversations with friends and family • Daily life and casual conversation Try different responses, make mistakes, and practice again at your own pace. LEARN THROUGH GUIDED CONVERSATION LESSONS Put new vocabulary and grammar to use as you learn. Guided lessons combine speaking, listening, and practical language in meaningful situations, helping you connect what you study with what you want to say. GET SUPPORT WHILE YOU CHAT Keep the conversation going while understanding more of the language: • Translate unfamiliar words and phrases • Access pronunciation and writing-system support • Check your grammar before sending a message • Understand mistakes and learn how to correct them • Save useful vocabulary as flashcards • Review words with spaced practice • Use saved vocabulary in new AI conversations WORK ON PRONUNCIATION AND LISTENING Practice the sounds that are difficult to hear and say. Record yourself, receive pronunciation feedback, and explore pronunciation patterns across accents and dialects. Train your ear to differentiate minimal pairs. Similar-sounding words that help you notice differences you might otherwise miss. MAKE YOUR VOCABULARY PERSONAL Save words and phrases you actually want to use. Review them with flashcards, then bring them back into conversation to practice remembering and using them in context. CHOOSE FROM 16 LANGUAGES Learn Spanish, French, Italian, German, Portuguese, Russian, Polish, Dutch, Swedish, Turkish, Arabic, Hindi, Japanese, Korean, Mandarin Chinese, or English. From your first phrases to more advanced conversations, practice at a level that suits you. GET READY FOR YOUR NEXT CONVERSATION Learning a language opens doors to new places, new people, and to new opportunities. Parlo gives you space to practice speaking, ask questions, notice patterns, and try again. Download Parlo and start turning what you know into what you can say.

About

Rosetta Language Reader

Features
Read full description

Rosetta turns writing you cannot read into a lesson you can revisit. Photograph a sign, a menu, a label — even when you have no idea what language it is. Rosetta identifies it, translates the sentence, breaks it into words with readings and parts of speech, explains the grammar, and reads every word aloud. 39 LANGUAGES, IN ANY DIRECTION Rosetta teaches every language your iPhone can speak aloud — 39 of them, from Japanese and Korean to Thai, Arabic, Greek and Cantonese. Any of them can be explained in any other, so you learn Thai through Japanese, or Greek through Spanish, whichever you actually think in. A LESSON, NOT A TRANSLATION Every reading gives you the sentence, its meaning, each word with its pronunciation and role, the grammar worth knowing, and example sentences you can reuse. Scribble over part of a crowded page to focus on just that phrase. WORDS THAT STAY Save words into a wordbook for each language, add your own notes, and review them on a spaced schedule that brings each word back just before you would forget it. FREE AND PAID Rosetta includes 3 free AI readings. Wordbooks, notes, pronunciation and history are free forever — only AI readings are counted. Rosetta Pro removes the limit.
