Introduction

Neural Study is an offline-first learning hub designed to support students in areas with limited or unstable internet access. The platform delivers bilingual (English and Hindi) courses, quizzes, and downloadable learning materials that remain fully accessible even without connectivity. It locally caches lessons, securely syncs progress whenever a connection is available, and provides multilingual tools that empower both students and teachers—making it especially effective for rural learning environments.
