AT&T
Challenge
Spam calls were overwhelming customers. AT&T’s idea was bold: an AI-powered “Personal Receptionist” that screens calls in real time. But trust was fragile—how do you make people hand over their phone line to a robot?
Insight
Through iterative research, we discovered that control and visibility built trust. People didn’t just want AI to answer calls—they wanted to see it working, understand its decisions, and know it could be stopped anytime.

I designed a multi-modal experience across the flagship app, instant apps, and SMS:
The UX Tracker framework defined user needs—Trust, Control, Ease of Setup, and Caller Experience—mapped against 50+ prototype iterations and SUS testing (external score 92, internal 80).

Impact
Reflection
What began as an anti-spam tool became a study in digital empathy—AI that respects interruption, speaks politely, and earns trust one call at a time.
