SafeCall – First Place at HenHacks

Overview

There are moments when calling for help isn’t an option, when speaking up could escalate a situation or draw unwanted attention. Whether in a suspicious rideshare, being followed, or navigating an abusive environment, SafeCall provides a discreet, lifelike AI phone call that gives users an excuse to leave and a secure way to seek help.

SafeCall combines real-time conversational AI with emergency data logging, creating a system that’s believable, reassuring, and designed to protect.
