Call Annie

The app is built on the insight that conversational fluency is best developed through actual conversation rather than drills, flashcards, or grammar exercises and that many language learners lack access to native speakers or conversation partners at the times and frequencies needed for rapid improvement.

The AI tutor named Annie engages learners in natural, flowing conversation in their target language and provides real-time feedback on grammar, vocabulary, and pronunciation during the call.

Unlike typing-based language tools, Call Annie's video call format requires learners to listen and speak at natural conversational speed, building the real-time processing skills that separate classroom language knowledge from genuine conversational fluency.

The application supports a wide range of languages for practice, including English, Spanish, French, German, Japanese, Mandarin, and Korean, making it useful for learners at various stages across the most commonly studied languages globally.

Annie adapts the complexity and vocabulary of her conversation to the learner's current level, and can switch between languages within a single session for users who are developing proficiency in multiple languages simultaneously.

Beyond language learning, Call Annie also functions as a general AI companion for problem-solving, entertainment, learning about new topics, and travel planning. The AI's video presence and conversational intelligence make interactions feel more natural and engaging than text-based chat interfaces, particularly for users who prefer spoken communication to typing and reading.

Call Annie operates on a freemium model, with core functionality available for free. The premium Super subscription, priced at approximately $11 per month, unlocks extended call durations, access to premium AI models including ChatGPT and Claude, customized lecture and game themes within calls, and fully customizable AI character appearances and avatars. The app is available on iOS and Android.
