YOUR PERSONAL AI LANGUAGE TUTOR
A great private tutor connects each lesson to your life, notices where you struggle, and knows when you’re ready for more. Glottie brings that approach to your iPhone, combining natural AI conversation with a learning path, memory, and review that continue across lessons.
Tell Glottie you want to speak with your partner’s family, raise a bilingual child, or feel at home abroad. Practise breakfast with your daughter, meeting relatives, or talking with a neighbour. Your goals and interests give the conversation a purpose.
Ask for a slower explanation, try the phrase again, or move into a more demanding conversation. Glottie uses your practice and progress to adjust support, revisit difficulties, and build on what you can already do.
Useful preferences, learning goals, and progress carry forward. Review brings earlier material back into practice, while your course gives the conversation direction. You can spend more time on a difficult topic without starting over every day.
Preparing for a client meeting or an international trip? Tell the tutor about your role and the situations you face. Rehearse introductions, explain a project, and practise relevant vocabulary in context. The goal is useful communication in your world.
NATURAL, TWO-WAY CONVERSATION
Glottie uses OpenAI’s Realtime API for direct speech-to-speech conversation. You speak aloud and the AI replies in a natural voice, with room to ask questions, practise a response, or ask for help. Glottie adds the teaching structure: your goals, your progress, and a plan for what to practise next.
On demand, day or night, with internet access and available minutes
Voice technology by OpenAI Glottie is an independent app. Your tutor’s voice is AI-generated.

YOUR PERSONAL AI LANGUAGE TUTOR
The words you recognise on a screen need to become words you can use with another person. Glottie gives you one-to-one speaking practice: listen, find your own words, ask a question, and respond in the moment. Spend your learning time practising the skill you came for.
WHY SPEAKING PRACTICE MATTERS
A meta-analysis of 15 classroom studies found lasting benefits from oral corrective feedback in second-language learning.
Read the studyIn a small study of Japanese university learners of English, regular video conversations improved fluency and comprehensibility.
Read the studyConversation brings listening, recall, and expression together. Feedback helps you notice a gap and try again. Research supports these ingredients of language learning; that is why spoken practice sits at the centre of Glottie.
These studies examined language learning, not Glottie. They do not establish a fixed learning-speed advantage for this app. Progress depends on your starting point, practice, and goals.
PERSONAL PRACTICE, WITH MORE FLEXIBILITY
Five minutes before work. A conversation after the children are asleep. Glottie makes room for speaking practice when you have time, without booking an appointment. Personal AI tutoring can also cost substantially less than premium private lessons.

Speaking asks you to understand another person, recall words, and express your own meaning. Glottie gives you practice doing those things together, with explanations and chances to try again. Research on interaction and oral feedback supports this approach. Reading and vocabulary study can complement it, but spoken practice directly exercises the skill you want to use in conversation.
Your starting point, practice, and goals all affect how quickly you improve. Glottie helps you use your time purposefully: speak regularly, work at an appropriate challenge, review what needs attention, and connect lessons to your life. We do not claim that it makes you fluent twice as fast as another app or a human tutor; that would require a direct study of Glottie learners.
You are speaking with an AI tutor using OpenAI’s Realtime speech-to-speech technology. It can hold a natural voice conversation and respond to your questions. Glottie supplies the learning path and memory around that conversation. It is not a human, and it can make mistakes; it does not replace every kind of support or expertise a human teacher can offer.
Explore 33 languages and 1,050 supported language pairs on this website. Choose the language you want to learn and the language you want explanations in. Regional varieties, including European and Brazilian Portuguese, have their own learning pages. The app shows the language options available to your account.
Glottie carries useful learner-supplied preferences and goals between lessons, alongside your practice and progress. That helps the tutor choose relevant examples, revisit difficult material, and plan the next challenge. Tell it what matters to you, and correct it if a preference or goal has changed.
Yes. Tell Glottie about the conversations you want to have: speaking with your partner’s family, caring for your child, settling abroad, or discussing a project with colleagues. You can ask to practise vocabulary, phrases, and roleplay related to your work. Revisit a useful topic over several lessons, then try the same language in a new situation.
Yes. Choose A0 if you are starting from scratch, then select a plan to begin. You can use your own language for help, ask the tutor to slow down, and practice small exchanges before longer conversations. Your selected level is a starting preference, not a test result.
You can start on demand, day or night, with an internet connection and available minutes. Stop after a short practice or continue for up to 60 minutes in one session. Paid sessions require at least five minutes of credit to start. Plans have minute allowances; practice is not unlimited and service availability can vary.
Glottie’s US plans are $19.99 for 40 monthly minutes, $49.99 for 100, and $99.99 for 240. Using all the Essential or Steady minutes works out to approximately $30 per hour. The illustrated private-tutor example is Petra Zanki’s published $100/hour online rate in New York: Glottie costs about a third as much in this comparison. Other tutors may charge less, and unused monthly minutes increase Glottie’s effective hourly cost. Current local pricing appears in the App Store.
