Speak your questions. Get patient answers. Learn at your true pace.
Students lack personalized instruction and a judgment-free space to learn at their own pace, causing them to fall behind in one-size-fits-all classrooms.
VoxScholar is a mobile app delivering personalized instruction through natural voice conversations in English and local languages. Students speak questions and receive immediate, judgment-free explanations, practice, and feedback. The AI continuously adapts difficulty and pacing based on real-time comprehension, creating a completely private learning environment for students who have fallen behind.
