Abstract: : This project presents Lingo, an AI-powered foreign language learning platform developed to assist non-native speakers, particularly Indian learners, in acquiring proficiency in English, German, and French. The application is designed as an interactive, mobile-based learning environment that combines structured lessons, quizzes, and real-time conversation with an AI tutor. The core technologies include Natural Language Processing (NLP) for understanding user inputs, speech recognition for voice interactions, and machine learning for adapting lessons based on user performance. The front-end is developed using Flutter to ensure cross-platform compatibility, while the backend is built with Node.js to manage user data, responses, and AI processing. A key feature of the platform is the 3D virtual tutor, which offers both spoken and text-based interaction, simulating a personalized learning experience. The application includes modules for grammar practice, vocabulary building, pronunciation correction, and progress tracking. This paper outlines the design methodology, implementation details, and expected educational impact of Lingo. The project aims to demonstrate how modern AI technologies can enhance language education and make personalized learning accessible to a wider audience through an affordable, mobile-first solution.
