The Challenge

Overwhelmed Support, Frustrated Students

The platform's small support team couldn't keep up with the growing volume of repetitive questions.

  • High volume of repeat questions about enrollment, payments, and certificates overwhelmed a small team
  • Slow first response times for simple, high-frequency queries frustrated students
  • Scattered knowledge base with inconsistent answers led to confusion and follow-up tickets
Our Approach

An Intelligent Conversational Support System

We delivered a conversational system covering FAQs, policy questions, and account support with seamless human handover for complex issues.
