User Research
Findings

Personalized Real-Time Feedback
Real-time, personalized feedback on grammar, vocabulary and pronunciation drives higher learner engagement and confidence than one-size-fits-all corrections.

Integrated Study Companion
Learners value EduBot as a seamless study partner. It automates practice schedules, tracks goals, sends reminders and summarizes progress to keep learning on track.

Addressing the Speaking Gap
Speaking skills remain the most neglected area in self-study and require targeted conversation prompts, live pronunciation coaching and mock speaking tests.

Humanized Conversational Design
Empathic, human-like dialogue with personalized greetings, encouragement and light humor transforms EduBot from a tool into a trusted tutor and boosts repeat usage.
