Eggbun: Chat to Learn Chinese is an interactive AI Chatbot Tutor designed to help Mandarin Chinese learners improve their language skills in a fun and engaging way. With the help of Lanny, the AI Chatbot Tutor, users can learn and practice Mandarin Chinese as if they were chatting with a personal tutor.

The app offers a comprehensive learning experience, starting from the basics such as 'Pin Yin' and gradually progressing to Chinese conversation practice. Users can also improve their pronunciation and intonation with audio recorded by real people, boosting their confidence in speaking the language accurately.

Eggbun provides personalized lesson plans, grammar lessons, quizzes, reviews, lesson reminders, and a progress tracker to cater to each user's learning style and pace. Although the app currently supports only the Beginner Level, there are plans to add Intermediate and Advanced levels in the future.

For those looking for additional features, Eggbun offers Eggbun Premium, which includes unlimited access to all lessons, new and more challenging lessons, and personalized word lists and quizzes. The premium subscription is available for $3.99 per month, $19.99 for six months, or $29.99 for twelve months.
