Project 02

AI First Message Flow

Explored an AI-powered first-message experience to help learners confidently reach out to tutors before booking a trial. The goal was to reduce friction in an underexplored part of the funnel, increase learner confidence, and introduce AI as a supportive, trust-building tool early in the learning journey. This project focused on turning an informal but high-impact behavior into a guided, delightful experience that feels natural, helpful, and fully under user control.
